You can easily reset your water heater by tapping the red button inside. And you’ll find the red button near the thermostat in an electric water heater and near the furnace in the gas water heater.

Along with the resetting method, you must know the causes of resetting the water heater problems. Let’s get started.

3 Major Causes to Reset Your Water Heater     

When your water heater isn’t functioning as it should be, the first thing you should do is find out the causes. So, here are three major reasons to reset your water heater.

1. Connection Failure 

The water heater might stop working if the wires are loose or not connected properly. Also, it can prevent the water heating procedure and cause various safety issues like electric short circuits or gas leakage.

2. Thermostat Stopped Working 

If the wiring connections are okay, check the thermostat. Sometimes it can malfunction and produce excessive hot water. Plus, it can stop tracking the temperature. And the heating elements won’t work correctly. 

3. Faulty Electrical Panel

When all these parts work, the water heater can be stopped for panel issues if you use an electric water heater. In that case, it can increase the water temperature and affect the internal heating system. 

How to Reset Water Heater

The procedure to reset the hot water heater is relatively easy. You can reset the water heater within an hour or two, depending on the water heater you use. 

Mostly the most common water heaters are electric and gas. We’ll share methods for these two.

How to Reset Electric Water Heater

Electrical water heaters are seamless to reset within 3 easy steps. They are:

Step 1: Prepare the Water Heater

You might have already replaced the thermostat and elements, but we’re sure it’s still numb.

Don’t worry, as, in this guide, we’ll be comforting you with other reasons why the water heater is not heating after replacing the elements and thermostat. It can be faulty wire connections, defective parts, tripped breakers, broken wires, and many more.

Let’s detect it, shall we?

Reasons Why Water Heater Not Heating After Replacing Elements and Thermostat

So, before starting, you should make sure you have turned on your heater for at least 30 minutes to 1 hour. Most of the time some water heaters take this much time to heat on.

But if you did this already and still the water is not heating up, let’s see what might be the other causes!

●      Poor Wire Connection

The first and foremost thing that you should check is the wiring of the water heater. We mean, maybe you tried replacing hot water heater element or changing the water heater thermostat but did you watch out for all the connections properly?

It’s because poor connection won’t let the water be heated and no matter how many things you do, it won’t work. It’ll drop the voltage and as a result, the water will be the same as before.

You need to check the wired connectivity for that. And if you find any loose connection, congrats! You have just found out the problem. Just fix it and your heater will work like a pro!

●      Tripped Breaker

Next up, let’s discuss the circuit breaker part. So, if you checked the wire connections and if they’re okay but still the water heater not heating up, you need to go check your breaker.

Sometimes, the circuit breaker goes tripped even without knowing and that causes all the messed-up situations. You have to open the breaker box and check out the double pole breaker (it’s for the water heater).

If the breaker is down, you must know the issue. Pull it up and go see if the solution worked. We’re sure it’ll!

If the breaker still falls down, there must be a short circuit issue. This time you need to call an electrician.

●      Scales in the Tank

Your water heater needs flushing from time to time just like other machines. If you don’t do it, the scales will accumulate. As a consequence, your heater won’t work as accepted.

If you already replaced the thermostat and still no heat is there, it’s time you should descale the machine. You need to flush the tank and release all those dirty filters so that the water takes less time to heat.

Note that, the water tank needs flushing once a year to keep it fresh and clear.

●      Rusty Heater

Look, any water devices face the problem of rusting (of course after years of use). If your heater isn’t heating after replacing the thermostat in the water heater, you should immediately change the tank.

It’s because the tank in there is definitely rusty and that fact is causing the improper heating problem. Also, after some time, your whole heater will stop working.

Try to purchase a new tank and see how superiorly the tool works!

●      Hot and Cold Water Connections

At times the cross-connection of cold and hot water cause issues with not heating up the water efficiently.

We all know that both (hot and cold) pipes are separate. But if any chance the lines get mixed, your cold water will interfere with the heating process. Thus, you’ll face the hot water heater not heating in the correct way.

Plus, this problem can lead to other big difficulties that can happen to the heater, such as low performance and less durability.

If you replaced the thermostat and element and still your heater isn’t working, check the pipes. You need to call a professional repair person who can fix this complication.

●      Old Age

Another great reason why your water heater isn’t heating is probably because of the age of the machine. Of course, you won’t face a new water heater not heating ever, but if it’s been used for some time now, the issue may arise.

We mean, every product has its lifespan and if you use it after its expiration date, it’ll obviously slow down the performance.

So if you ever notice this heating issue with the heater, do all the above things first. And if those don’t work, know that it’s high time you should change the whole thing.

●      The Weather

Last but definitely not least, the outside weather plays a vital role in heating your water heater. If you live in the south, you’ll surely face so many difficulties because of the cold and dry temperature.

The water will take a long time to heat. No matter how many times you change the elements or the thermostat, it’ll take a decade. Be patient and wait.

Analyze the Matter Early and Solve It!

To sum up, we can say you should definitely be observant if you smell the above cases with your water heater. If it’s not heating properly, you need to identify the exact problem and fix it as soon as you can.

Or else you can take the machine to the professionals (if you want). They’ll point out what’s wrong with it and will repair it for you.

Just don’t neglect the fact because if you do, other issues may arise inside the heater, such as smelly water, lighting problems in the heater, noise issues, dirty water, leaks, low water pressure, and no heated water.

Frequently Asked Questions

●      Why is my water heater not heating?

Your water heater might be facing some issues inside. For example, the tank might need descaling. So you need to flush it. Then again, your weather situation outside might be very cold and in this case, you need to wait. Therefore, it can be some poor wire connections, tripped breaker, or even the heater’s age.

●      Can a water heater element test good but be bad?

Well, it’s very rare that your heater element is bad but it’s showing it’s good. In this case, you can try to push the ‘High-Temperature Button Cutoff’ which is situated above the thermostat. Pushing it will solve your heating issue and if it doesn’t, go to the repair shop.

●      Which element comes on first in a water heater?

In a water heater, the top element always comes first. It turns on in the beginning to warm the upper part of the tank water. After the top half is set with a specific temp, the top element switches off. Next, the bottom element starts to heat the rest of the water.

Conclusion

The issue with the water heater not heating after replacing the element and thermostat is quite common in every household. All you need to do is calm down and find out about the other reasons your machine went blank.

Once you analyze the exact problem, it’ll be easier for you to solve it. And if you don’t want to do that, there are always professionals out there to help!

However, never be too late to identify the subject as a little bit of delay can cause harm to your tool and even your household.

All the best!

How to Test Water Heater Thermostat

Instantaneous or demand-type water heaters deliver hot water just when required and don’t store it in a tank. Standby energy losses from storage water heaters are avoided, allowing you to save money. For that reason, some small issues may arise from time to time, such as no hot water or a malfunctioning burner.

That’s why in this article, we’ve talked about the reasons behind a tankless water heater not working. Not only that, throughout the article, you’ll get to know how you can solve those problems or whether you need a plumber.

So let’s get started without cooling your heel.

Tankless Water Heater Problems You Will Face

Investing in a tankless water heater is a smart move for your house or business. Additionally, they can save you money by boiling water just when it’s needed. If anything isn’t operating correctly in your water heater, problems might occur.

Here’re some of the most typical tankless water heater issues and maintenance concerns:

Deposition of Minerals

The expectation is that you’ll see clear and pure water every time you turn on the shower. You know what it’s supposed to smell like and can detect when something isn’t quite right with it.

If you notice discoloration or an unusual odor whenever you turn on the hot water faucet, something is probably interfering with your tankless water heater.

Despite the fact that this seems to be a terrible situation, it’s not as bad as you may imagine. Tankless systems are constantly exposed to the minerals in your tap water since they do not have a filter.

As you use the heater, minerals might begin to accumulate within the lines and throughout the system. Once the minerals have accumulated to a sufficient level, the water may begin to smell when the faucet is turned on, and it may seem hazy, yellow, or even brown in appearance.

Simply flushing your tankless hot water heater with vinegar or a descaling solution will take care of the problem. To ensure that you understand how to flush your unit, have the plumber guide you through the procedure.

In order to prevent accumulation from occurring in the first place, it’s recommended that you flush the system once every six months. Even better, by doing so, you’ll be able to prolong the unit’s life and ensure that you’ll always have hot water available when you need it.

Overburdened System

If your tankless water heater is supplying an immense amount of hot water at the same time, there’s a high chance that it can get overheated. In that case, it may struggle to provide the hot water you need, or it may even shut down completely.

Whenever this occurs, you should lower the demand for hot water by minimizing the number of simultaneous uses and try resetting your water heater. You can do one more thing to avoid this situation: upgrading to a tankless water heater with a bigger capacity or installing a second unit.

Although purchasing a second unit may seem to be a significant financial commitment, doing so might save you money in the long term since you’ll be using less water.

Blockage in Air Supply

The majority of tankless systems are intended to make troubleshooting difficulties as simple as possible.

When anything is amiss with the system, the display will at the very least offer you a general notion of what’s wrong with the system. An obstructed exhaust notice is the first and most typical problem message that most homeowners will encounter.

Tankless systems need access to fresh air at all times while they are in operation. It’s also important that they have a way to vent to the outside while they’re actively heating the water. If the exhaust is obstructed, they won’t access the air to keep the heat maintained.

Ensure that the exhaust channel is open if you are receiving an error message about the exhaust. Check the area around the water heater for dust bunnies and other things that might be obstructing the vent. Check around your home to see that any openings are clean of debris and free of obstructions. If you can’t locate anything that is obstructing the vents, contact your plumber to arrange an examination.

Fluctuations in Hot Water

The fluctuation in temperature is also known as a cold water sandwich. Now you must be wondering what a cold water sandwich is? Well, let’s tell you what it is and why this happened.

Consider the following scenario: A member of your family has just completed bathing, and it’s now your time. When you switch on the shower, you’ll first feel the warm water, but you’ll then be blasted with cold water for several seconds until the temperature gradually returns to normal.

Some hot water was left in the pipes leading to the second shower even after the first shower. When the second shower started, the warm water you felt at the beginning was trapped water.

If your shower water is chilly, it’s because there’s a lot of cold water in the pipes that go from the water heater to your shower. With each additional mile of travel, you’ll notice a distinct difference in water quality.

You can’t avoid this problem, but now that you’re aware of the issue, you can wait till the cold water has gone before getting in.

Ignition System Failure

A variety of factors might cause the failure of your water heater to ignite. Often, the gas supply is the source of the problem, so check that your propane tank is fully charged before proceeding.

Additionally, if your gas or water valves aren’t completely opened, this might result in the ignition not working properly. Check and completely open the gas and water valves.

If following these methods doesn’t address the ignition problem, it’s possible that your ignition pack has failed or that there is a more serious issue. You should contact technical support to troubleshoot the problem and, if required, place an order for new components.

Making Noises

Is your water heater making noises? If so, is there a low rumbling or popping sound when you turn it on? What if it’s a high-pitched whine instead?

The sound you’re hearing may be the sound of boiling water. When there’s a significant amount of sediment building in the bottom of a tank, it may cause the bottom of the tank to overheat, resulting in the water boiling.

In order to remove the silt from the tank, the first thing to attempt is to empty it. The tank may need to be replaced if this doesn’t alleviate the problem.

Can You Fix the Problems by Yourself, or Need to See An Expert?

There’re different types of tankless water heater that may arise. The user can solve those problems like cleaning inside the heater, whereas some issues need to be checked by experts.

In that case, you’ve to make your mind to spend some money on plumbers. The typical plumber’s hourly rate ranges from $45 to $150. A tiny, cheap item is typically paired with a significant labor charge in water heater repair costs.

Even if the cost is high, the peace of mind is worth it if you’re opposed to tinkering or unsure of your diagnostic skills.

How Much Does It Cost to Fix the Problems?   

As reported by HomeAdvisor.com, the average cost to repair a water heater is $501, with the majority of homeowners paying between $203 and $800 for a single service call.

There’ll always be parts that are more expensive to repair in a household appliance. The following is a list of the most frequent boiler repair costs:

1. $175–$485 to replace an ignition switch. Boiler ignitor sparks/heats the fuel, causing the combustion process to begin (oil, gas, or propane). To create heat, the fuel must be ignited. It’s thus impossible to heat the house without a working ignitor.
2. Removal of mineral deposits might cost between $150 and $450. Limescale may develop up in your boiler tank due to mineral deposits from hard water. This might cause the system to overheat because of a lack of heat transmission.
3. The replacement of the expansion tank will cost between $230 and $650. An overflowing expansion tank might cause your boiler to overheat or leak, which means it must be replaced.
4. It can cost from $435 to $1,800 to replace the circulator pump. Your heating system won’t operate if your circulator is broken.
5. Pipe leaks may cost anything from $55 to $350 to correct. Your boiler unit’s pipes might burst, reducing the system’s effectiveness or causing it to cease operating.

Other charges (apart from just the water heater itself) may also play a role in overall repair costs.

It’s possible that the water heater’s mount, supply pipes, airflow system, and drain pan may also need to be improved or changed depending on when the water heater was first installed and any new building requirements that demand compliance.

How To Fix the Problems of Your Tankless Water Heater

A tankless water heater needs to be flushed every six months to two years because of the tiny openings in the water heater. Plus, a flush may be necessary if the water flow becomes sluggish. You have the option of hiring a plumber or doing it yourself.

If you want to clean all your own, a 5-gallon bucket, two hoses, and 2 gallons of white vinegar are all you’ll need for this project. However, you can follow the steps given below during the cleaning.

1. Uncover the unit. Close the water supply valves. For gas units, remove or switch off the electrical supply. Close the 240-volt circuit breaker for electric units or depress the disconnect button in the subpanel to stop the electricity. Relieve the water pressure by pulling out the silver tab on the pressure release valve.
2. Add vinegar to the sump pump or submersible pump suction pickup. Connect the water heater’s intake to the sump pump and the pressure-relief valve to the bucket via hoses. Allow the pump to flow the vinegar through the water heater for 15–20 minutes.
3. Remove the inline filter housing from the water intake. Replace the screen filter after cleaning it.
4. Remove the pump from the bucket and quickly operate it to discharge any vinegar. Refill the bucket with clean water. For a few minutes, flow clean water through the system by putting in a pump and turning it on. Turn off the hoses, then on the water and electricity.

This will not only help you to bring back the heater to a factory reset position but also find the exact solution for the problem that you are facing with the product. So, let’s start with Rheem tankless water heater troubleshooting.

Rheem Tankless Water Heater Troubleshooting: Error Codes

1. Troubleshooting: Error No Code

What it’s telling you

This happens mainly when the flow rate is low and there is a complete maintenance error. In such a situation, the control board simply displays the current temperature and the heater does not work at all.

The Solution

1. The first thing that you need to do is to adjust the flow or the temperature.
2. Once you are done, check all the pipelines for both the inlet and outlet connections. Make sure that they do not cross the lines.
3. Make sure that there are no technical mistakes while plumbing and you are free to use.
4. Try to wash the filter present. There may be some sediment stuck in the inlet filter that is causing the problems. Try to rinse it with clear water.
5. Complete a full diagnosis of the flow sensor. You may find multiple problems with it or it may be jammed.

2. Troubleshooting: Error P1

What it’s telling you

This error seems to be very common when there is a situation for maintenance. It is a warning when the water flow is too low. However, in such a situation, the unit may operate but with a lower flow rate.

The Solution

1. The first thing that you need to do is to check the water pressure from the aerator. If you feel the pressure is low, try to clean it.
2. There may be sediment formation on the filter. So bring out the inlet filter and then wash it thoroughly.
3. If you are done, adjust the temperature or the flow rate of the heater. If the flow rate does not increase, try any other temperature that may work.
4. If none of the above steps work properly, the only thing left is to inspect the flow sensor. Try to contact a professional if you are not able to do this all by yourself.

3. Troubleshooting: Error 1L

What it’s telling you

Having this error means that it is time for servicing or cleaning your heater. There is a formidable amount of limescale build up in the heater.

The Solution

1. The first thing that you need to do is to flush the heat exchanger. If you cannot do it by yourself, try to read the manual and get an exact idea on how to do this.
2. The next thing that you need to do is to adjust the altitude settings. The settings must be pre-set at a lower altitude and thus it allows easy build-up of limescale.

4. Troubleshooting: Error 05

What it’s telling you

There may be two major reasons why this error code is showing up. The main reason for this could be a blockage in the bent or the pipes are not properly joined.

The Solution

1. If there is a problem with the vent installation, you need to check for the fittings. If you find any spare parts as loose, simply join them to make them sit tightly.
2. If there is a blockage on the vent, you need to clear the vent with a blower. Try to remove all the dust particles.
3. Now, you need to fit it back again following the installation norms. Make sure that the vent sits properly onto the heater.
4. The last thing to do is to check the fan motors. You may find that the fan motors are full of specks of dust and it has become heavy. Clean it and then install it again.

Why Does It Need a Reset?

There are multiple reasons why any tankless heater might require a reset. One of the most common causes of this may be overloading. If there is overloading, even the largest of the tankless units will fail to deliver you the expected requirements for your home.

As a result of this, it will always show an error and will stop working. But to get it back to the original position, trying out a reset on the unit may work for you. The best solution is to follow the procedure to complete a full reset and bring back the configurations to a factory set point or a default setting.

If it is not working with just a reset, you may require contacting a professional. There may not just be a problem with the overflow, but any other spare part of the heater may not be working correctly. As a result of this, adding a second heater may be just the ideal solution for your needs.

Why Do Water Heaters Have a Reset Button?

The reset button in any electric heater works like a recovery. Suppose the heater is stuck at a particular stage and it’s not working after this. Here, the reset function can bring back life to the heater. So having a reset function can be highly beneficial for every home. But at the same time, the reset button helps the heater to run safely and without any problems.

So when the heater is under extreme pressure and comes with overheating, the reset button comes to proper use. Apart from this, there are a few reasons when the reset button might come to work.

1. A Faulty Thermostat

The reset button may come to work when there is a faulty thermostat in place. If this thermostat is not working properly, the heater may not function as well. Because of this, the reset button will activate itself.

2. Loose Connections

The loose connections may happen at any time and it may lead to a fire hazard. Having the reset button here may just be helpful for you to get rid of such dangerous situations. The reset button has multiple sensors that can always trip off when it senses an issue with the wiring of the product.

3. A Poor Heating Element

Another good reason why the reset switch may just be important for your heater is the heating element. In any heater, it is one of the most important parts to consider. Whenever it is not working properly, the heater sends signals to the reset switch and asks it to send an electrical current through the unit to bring back the heating element to work.

How to Re-Light Your Rheem?

When your water heater is not working, there may be some hardware or technical faults. However, it is not at all difficult to consider when you have to turn it on. If you have turned off the system for flushing or cleaning, you can follow the safe steps to turn it back on.

1. The first thing that you need to do is to shut down the valves. Make sure that there are no open gas valves or any type of leaks present around the knobs. Simply turn the knob in a clockwise direction to make sure that you have set it in the off position.

2. The next step that you need to do is to set the thermostat to the lower temperature. If the thermostat is a dial and adjustable feature, you need to rotate it counter-clockwise. This will let it set in the lowest possible temperature and then you have to wait for at least 5 minutes that will allow the gas to pass through.

3. Once you are done with this, you need to remove the outer door. Lift the outer door so that you can reach the gas knob once again. To start the heater, you need to get the gas knob back to the pilot position again.

4. After this, you need to turn on the ignition. This is practically present to the left side of the gas knob. If you look closely, there should be a red button present around the ignition. You can easily hold it down while you press the ignition button present. You should find the ignition sticker around the right side of this knob. So you need to press it down until it turns on. You can check the viewing window.

If you are done with all the steps mentioned above, the heater is almost ready to start. At this point, the water will start to flow in and you need to turn on the gas valve. This will help you to set the temperature to a specific range and then re-light your Rheem.

Conclusion

Rheem tankless water heaters come with a programmable display screen that includes several error codes. Since most of them have a self-diagnosis platform, they display the error code so that it takes less time for you to solve it.

If you are unfamiliar with the error code on display, you can either look at the manual provided or the guide that we have mentioned above. Following the steps will surely help you in Rheem water heater troubleshooting.

If you are still unable to find the relevant information you are looking for, just drop down your comments and let us know here. Do mention which error code your Rheem water heater is displaying.

A defile water heater can cost you a fortune. Repeatedly asking for a professional to patch up the heater back to work is not a matter of a few bucks, but replacing the entire heater can cost you a lot. But if you diagnose it properly, you may end up saving a lot.

But what’s the most important part of any electric water heater? Yes, you guessed it right- it’s the thermostat. To be fair, each of the electric water heaters does come with two thermostats present.

One of them is found at the top while the other is at the bottom of the tank. This is why each of them controls different heating elements in a heater.

If you turn on the hot water faucet, the cold water freezes out and if you feel that the hot water is not pouring at all, it’s because there are multiple issues with the thermostat. When the first thermostat is partially damaged, you’ll find that the cold water is not coming out of the heater.

If the water becomes cold, it means that the lower thermostat is also damaged. But how will you know which part is damaged without even testing it?

This is where thermostat reading is effective. With the help of a relevant test, you’ll be able to find out which of the thermostats have a faulty mechanism. So, let’s start this guide on how to test water heater thermostat.

How Does A Water Heater Thermostat Work? [Electric Water Heater]

When it comes to the mechanism, the thermostat is the most important component of the heater. Technically, it is much more important than the heating element and the switch. The primary role of the thermostat is to regulate the temperature and the heater safe from any type of excess threat.

So this device is used to produce high temperature water for multiple purposes in case of both tanks based and tankless water heaters. This is mainly because the levels of heat needed for a shower is completely different from the level of heat needed for washing. Apart from this, the simple controlling gadget also can control the current from the thermostat to the heating element.

Any heater that comes with both electric and gasoline ignition with 25 gallons of storage space must have two different heating elements. For each of these heating elements, you will be able to find a thermostat for each.

But when it comes to the working mechanism, the thermostat present on the top may act as the primary regulator. This is mainly because it will have a high limit switch. The main function of the lower thermostat is to detect any rise or fall in the temperature.

As a result of this, both these devices have different properties for working. Infact, they may not even work together. For safety reasons, this high limit thermostat comes with a switch that can always stop the thermostat from working.

To keep the water temperature safe for use, the manufacturers set a higher limit to 170-degrees Fahrenheit. If the water temperature is higher than this, it stops working.

If you want to fix the thermostat with a specific range of temperatures, you need to make sure that they are on the same temperatures. To get this done, you can pick out the readings for one of the thermostats (the lower one will be the better option) and match it with the other thermostat. Once they are set, activate one of them.

However, if there is only one thermostat present with the heater, it means that you don’t have something to match with. Pick out a decent water temperature and you can adjust the dial of the thermostat to fix it at a specific temperature.

How To Test Water Heater Thermostat?

Before you plunge in to check the thermostat, you need to keep in mind about checking the heating element as well. You will have to check all the details including the temperature, the response of the electrical circuit to the thermostat, and much more with the help of digital tools. The open as well as grounded heating elements can bring out different tests.

Thus, being sure about the measurements is a must. Thus, having a digital multimeter may come to be very handy for you. You need to be well prepared with the right set of a tool other than just the testing equipment. This is because the process of testing will involve a complete assembling of the heater.

So having a screwdriver and a few faucets is a must. You can just follow the steps mentioned below to get a quick test done to the thermostat.

1. You need to start by checking the terminals and then look for any type of power supply. For the measurements, the most important thing is the keep your power turned on until it ends. If it is working correctly, it should be giving you a reading of 240 Volts on all the terminals. If you do not find any reading or a lower reading, you need to check the power source and the high limit for your current.
2. The next step is to stop the lower thermostat. This will mean that you need to rotate the dial to the lowest limit possible. Once this is done, you need to higher up the thermostat in terms of temperature. This will give you a clear idea of where the problem lies.
3. To get the readings you need to set the prongs to the terminal 1 of the thermostat. Make sure that the multimeter is properly connected with the heating element with the other prong. When the power supply is on, you will immediately start getting the readings, and without any delay.
4. If you find the readings to be around 240 Volts, the thermostat is getting adequate power supply. Change the locations of the prongs to the terminal 2 and then check the readings again. The readings should match on both the terminals. If not, consider it as faulty part.
5. Now it’s time to check the lower thermostat. You can start by adjusting the dial from the primary thermostat to the lowest possible temperature settings. Set the dial of the lower thermostat as per the maximum limit possible.
6. Once you are done, set the prongs on the terminal one and other to the red wire present on the lower heating element. If the power is turned on, you will also get an immediate reading. It should be around 240 Volts to declare that the thermostat is working fine.
7. Change the location and then set to the terminal 2 of the thermostat. If you find any similar readings, the device should be working fine. If you are unable to find any deflection, you need to end up replacing both the thermostats together.

Water Heater Thermostat Replacement

Changing the thermostat is never as difficult as it may seem to be. If you have done the entire process of testing the thermostat, replacing it is just the next step. Before you start with anything, you must know which thermostat you have to change and the health of the other one.

But if you are willing to take the help of a guide to save yourself from spending lots, you can just follow down below. If you are unsure about the entire process of bringing out the thermostat and then replacing it with a new one, leave it for a professional to do.

1. Turn off the power supply

If you are putting your bare hands deep into the heater, you must be sure of no power supply. Make sure that you disconnect the power input supply and then take the help of a screwdriver. You need to chop off the power supply from the circuit breaker as well. Taking out the panel is a must before you dig into the heater.

2. Pull it out

The next thing would be to bring out the thermostat. But before you do this, take a picture of the wirings and the configuration as this will help you to re-install the new thermostat. Unscrew all the tightening and then you will be able to bring out the thermostat with a minimum pull-over force applied.

3. Replace the thermostat

I’ll assume that you already have the new thermostats and now you need to push it back in. Follow the same procedure to install the new thermostat to the original place. If you get confused about the wirings, just have a look at the picture that you have taken earlier.

4. Reconnecting the circuit

Now that you have installed the thermostat, it’s time to check back the status. Join it up with a new circuit and you will be able to know the status. Switch on the heater for at least two hours and change the dial settings to a decent temperature. Open the high temperature faucet to check if it is working properly or not.

Electric Water Heater Thermostat Troubleshooting

To be fair, troubleshooting may seem to be a bit out of reach for any person who does not know how to fix things up. But from a professional’s point of view, it’s just a 10-minute game. If you follow these instructions, you’ll be able to do it accurately and without much external help.

1. The first thing that you need to do is to head up to the circuit and then simply turn off the power supply line. When you touch the thermostat, make sure that your hands are dry to avoid any type of electrical shocks. Try to stay away from any pole breakers as it may not be a great idea to use them.
2. The next thing that you need to do is to pull out both the panels and then uncover the thermostat. Behind these panels, you will find out the insulation of the thermostat. Bring it out as well to avoid any damages while working.
3. Once you are done with this, you need to find out the plastic panel present on the thermostat and also the heating element. Here, you will find a button present. Simply press it to ensure that the button is working fine and is receiving connections.
4. After this, you need to hear a snapping sound as you push the button. If it is working fine, there should be the sound of the switch turning on. If you wish, you can turn on the power for a few minutes to check if the switch is working fine or not.
5. Even if you switch off the power, you need to make sure that there is no external supply present. To check this, you can take the help of a voltage tester and then place the probes on the wires at the top. If there is no deflection, it means that you are good to go.
6. Take the help of proper rubber gloves that will ensure no trespassing of electricity. Now you can slowly take out the plastic cover. You can easily take the help of a small clipper to bring out the cover.
7. Once you have taken out the cover, you need to turn on the power again. Now bring in a voltammeter that will give you proper readings. Try to take a test lead on all screws. You should find the same power readings on all of them. Repeat this process by turning off the heater.

If you want to replace the water heater drain valve, it does not mean that you need to be a professional or even call one. Following a simple guide and taking care of the safety precautions could save you tons of money. Replacing the drain valve for the first time will require time and concentration, but it’s not so tough to accomplish either.

Leaks may happen at any time depending on the local water quality. So following the steps and doing everything by yourself could save you at least $100 every year. So let’s commence the DIY guide to know how to replace water heater drain valve.

There are two main procedures that you can follow for doing this. One is by draining the tank and the other is without draining it.

Procedure 1: How to Replace Water Heater Drain Valve By Draining the Tank?

The drain valve always stores some amount of water inside the tank. So if you remove the old valve, it will release the water inside and start to flow out. Thus, draining the tank is important if you are using any gas water heater or an electric water heater.

1. Turn off power

The first thing that you need to do is to turn off the power that is in use. If you have a gas ignition system, make sure that you have turned that off as well. Now you can switch off the connectivity from the electrical service panel as well. This step will stop the burners from working and then you can easily shut off the gas supply of the heater.

2. Close the water supply

The next thing that you need to do is to stop the water supply. Close the faucet that allows cold water to flow inside the heater. There should be a supply pipe fitted at the bottom or top of the heater. Make sure you close it to stop the flow.

3. Connect a hose

To allow the tank to drain out the water, you need to connect it with a hose. Draining with the hot water faucet will not be a good option. So, connect it with a garden hose and then put the other end of the hose to a nearby floor or a drain.

4. Draining the tank

Once you are connected to the hose, you can start the procedure for draining the tank. To get this done, you need to open up the T&P valve present on the top of the tank. It will release the pressure inside and allow the water to flow out. Let the tank finish the draining and the heater should settle in for a while. If you have a big heater, it will take about 15 minutes.

5. Remove the old valve

Now the heater will be completely cold and free from any hot water. This will be the best opportunity for you to remove the old valve. You can turn it in the counter clockwise direction and then pull it out with the help or a range.

6. Replace the drain valve with a new one

The next thing that you need to do is to get a new drain valve and then push it once into the slot. Keep turning it clockwise until the valve sits in the proper position. Once it does, you can wrap the threads with the help of a plumber’s tape so that there are no leaks in the future.

7. Turn on the water

Start with opening the cold water inlet tap present inside the house. This will allow the heater to start refilling the tank. Allow some water to flow inside it and then you can turn on the hot water faucet.

8. Turn on the Power

When the cold water settles inside the heater, you can now power it on and then allow it to ignite. This will start heating the water inside the tank and then your heater will be ready for uses.

9. Check the valves

Before you close the cover, look for the valves that can be spotted. If you hear any whistling noise, stop the heater and look for the leaks. The heater is otherwise good to go.

For the draining process you will need a Water Heater Flush Kit. We have a detailed review regarding that. Check it out to choose the best one for you.

Procedure 2: Replace Water Heater Drain Valve Without Draining

It has to be a tankless water heater when you want to approach and change the drain valve. There is no water stored in the tank and the only water to come out will be from the flow pipe. So immediately replace with a new valve once you bring out the older one.

1. Turn off the power

You can start the procedure to turn off the power and the gas valves. This will allow the heater to stop functioning. Then you need to turn off the water supply on the heater. This will create a vacuum inside the heater.

2. Prepare the New valve

The next thing that you need to do is to use a Teflon tape and then wrap around the new replacement part or the drain valve. You can keep it ready so that there is not much water loss.

3. Place a bucket

Place a small bucket so that the hot water inside the tank falls directly within the bucket and not on the floor or your feet.

4. Bring out the old valve

Twist and turn the valve to open it and allow the water inside the heater to flow out for a few seconds. This will release the pressure inside the heater. If the pipe is made up of PVC, it will quickly spray the pressure.

5. Replacing the valve

Once some water is out, quickly replace it with the new valve. Apply some pressure from outside so that it sits correctly in the proper position. This will not allow you to lose much water and the heater is ready for use.

Conclusion

Replacing the drain valve is not as difficult as it looks. But be very sure to wear the protective gear and always place a tub underneath the heater. If by any chance the water inside the tank starts to leak, it should not touch your feet.

If you are unable to do it even after this guide, try to contact a professional and leave the heater as it is. Handle the heater carefully and try not to break any other part while using the wrench.

Do let us know which procedure you liked the most. Also, put down your other queries regarding the hot water heater drain valve replacement below in the comments section.

Is there any recent decrease in water flow from the tankless water heater?

This could be a sign of the interior components wearing out. Even if there is no tank present, the heater is sustainable for the formation of sediment buildup and limestone. Things can get very quirky if there is not a service taking place.

This is why flushing the tankless water heater is recommended. Most of the manufacturers do recommend flushing out the units at least once in a year. The statistics though say that sediment formation can start from two months of purchase.

This depends on the water quality and the resistance for the heater. If there are traces of hard water, the formation of mud and rusts are too common. There’s always special equipment for the removal of these rusts and that’s a flush kit.

The flush kit seems to be a great tool to have for your home. It’s even better if you have a tankless water heater available in your bathroom. Since flushing the heater is a mandatory part, these kits are designed to exactly do the same but to make it much faster and easier for you.

Now the basic requirement of flushing often completely depends on the locality that you have. If the local water is hard, you’ll have to do it every six months. If you do not have hard water, flushing your heater every year can be a good choice for anyone.

Calling out a professional every time you face issues with the heater can cost you a lot, especially when it is just about descaling rust and limestone formation. Having a flushing kit means that it’s a one-time expense and a few efforts from your end. If you are a DIY type of person, these kits can come to be very handy for your use. Compared with the regular heaters, they have a filter present with the tank.

But on the tankless heaters, there are none. As a result of this, mineral built-up is much faster over here. Apart from this, any tank based heater will experience the sediment formation at the bottom that does not stop the flow of water. But in the case of the tankless models, the sediment formation occurs at the flow pipe. It directly blocks the flow causing a lot of problems to the interior components.

This is the main reason why you may need a flushing kit. Not only to save yourself from paying a fortune for buying a new heater, but the flushing kit can help you to get an easy solution to your problems and at the earliest. It saves up a lot of time from calling out a professional, to waiting for them to arrive.
