then opt for resetting it. So, to help you out, this article will highlight how to reset the water heater so you can enjoy warm water as expected!

Resetting the Water Heater

If you have the experience working with electricity only then you can follow these steps. Or else we would advise you to contact a professional. Before resetting you can test your water heater.

Step 1: Disconnect the Water Heater

Have a visual inspection of the water heater conducted to check out if the reservoir is leaking or the TP valve of the water heater is releasing water. The TP valve basically stands for temperature and pressure relief valve. The TP valve should be placed on or close to the top of the water tank. On the basis of the location of the leaks, water can be found on the top, bottom or sides of the heating device. You can also find water on the floor or walls around it.

If water is present, then you have the turn off the breaker from the electric panel prior to approaching the water heater. Once you turn that off, you need to turn the water off via closing the valve above or near it. Note that you have to close it clockwise. If the area is dry, you also have to turn off the breaker so you can examine the cause of the issue.

Step 2: Take Out the Cover Plates

Take out the cover plates from the face of the water heater. You will basically find two of them. The energy cut-off or ECO which is the high limit switch is a safety device that helps cut off all the power connected to the upper and lower elements and their thermostats when overheating occurs. It should be located below the top cover and affixed against the reservoir above the upper thermostat directly.

In general, the energy cut-off trips when the water temperature in the reservoir gets in the range between 150 to 180 degrees Fahrenheit. But that depends on the sensitivity of the heater. You cannot reset such a safety device until the temperature of the water is cooler than that of the temperature in which the energy cut-off got tripped. This ECO switch basically differs from the exact temperature drop that is required.

Step 3: Take Out the Insulation Pad

You will find a foam insulation pad right there inside the water heater. It helps conceal the button you which you need to access to reset the unit. You will have to take the pad out with your hands and keep it aside. There you will find a reset button which is red in color on the ECO. If you find any moisture surrounding the reset button or on the pad, chances are that the element gasket is leaking. So at first, you will have to fix the leaking. Then press the button to reset the water heater. You will hear a clicking sound if the heater has cooled down adequately and that the energy cut-off is working appropriately.

If the button does not click immediately, then keep your finger pressed against the button until you get the click sound.

What if you don’t hear the click?

If you do not get to hear the click after you press the reset button, then you will have to examine all the wires of the heater for loose wire nuts. If you think the wiring is fine, then perhaps you need to replace the controller.

Different heaters work in different ways. While some of them click immediately, some take five seconds to click. If you still don’t hear the sound, then reassemble the heater anyway as it will still restore the hot water.

If the Switch doesn’t Reset

Step 1: Thermostat Replacement

Replace the thermostat if the switch of energy cut off device fails to reset or if it trips frequently. Do the replacement task only if you have experienced, or else you will have to call an expert or a plumber to analyze and repair the issue.

Step 2: Interior Parts Inspection

Investigate the interior part of the heater for the sign of burn or overheating. If you are someone professional DIYer, then you can change the burnt-out thermostats or heating elements. Besides, you can also change the anode rod if required. But all of these are dependent on your comfort zone and your experience. When the anode rod gets corroded, it affects the functionality of the water heater This kind of rods have been engineered to be a sacrificial part of the water heater so you can sacrifice it and get a new one when the existing one deteriorates.

Reassembling the Heater:

Step 1: Put back the Insulation Pad

You will need to put the insulation pad back to the heater. Take the pad which you had taken out earlier.

Step 2: Screw Back

Then you will need to put the door on the control panel back in place and then screw it to fix it.

Step 3: Turn the Power On

Then have the cable plugged in for restoring the power. You can also flip the necessary switch for that. Wait for a few hours, your water should be heated by then to run properly.

Wrap Up!

So, this is how you reset the water heater. You have to be very patient while performing all the steps. However, If you have no idea regarding the way to switch off and reset the heater, then it’s better you call an expert to do that for you. It would be very risky to mess around with a water heater if it’s turned on.
