Here is a step-by-step process on how to reset tankless water heater – 

1. Disconnect The Tankless Water Heater

Before inspecting the tankless water heater, it is essential to disconnect it from the power source for safety reasons. Search the unit for the cable that links the unit to a power source. Ensure no electricity is running to the heater before beginning your inspection.

If the existing tankless water heater is wired to the circuit breaker box, turn the switch to the ‘off’ position. So, there is no power going to the tankless water heater.

It is possible to move forward with the process once the tankless water heater has been disconnected from its power supply.

2. Remove The Cover Plate

Older tankless water heaters have a cover plate that can be taken off using a Philips or flathead screwdriver.

There’s a protective plate over the front side of the device to guard its internal components from the outside environment. When you find the cover plate, you will observe a minimum of two screws keeping it secured. 

Unscrew and take off the cover plate and place it to the side. You will need to put back the cover plate after you are done. If there is no cover plate, continue to the 3rd step.

3. Take Out Insulation

You will probably detect some insulation when you take off the protective cover. This insulation provides an additional shield between the covering plate and the water heating unit. Take away the insulating material from the tankless water heater.

Check the insulation for any evidence of dampness. The presence of moisture may be indicative of other issues. If you find any wetness, contact your plumber for further guidance.

If insulation is absent in your system, proceed to the subsequent step. You can contact your plumber if you are interested in having insulation in your system.

4. Locate The Reset Button

Generally, the reset button of a tankless water heater is found on the front of the right side. However, if it is outside of these places, you should check the back of the appliance.

If you cannot locate the reset button, contact customer service. The producer of the tankless water system should be able to assist you in tracking down the reset button.

Once you locate the reset button, you can press it.

5. Ensure That The Tankless Water Heater Is In Reset Mode

Once you have identified and pushed the reset button, ensure your tankless water heater has gone into reset mode. The reset mode must be active since it allows the tankless water system to start functioning again.

When the reset mode has been activated, the internal functions will begin again, and the system will reboot. A successful reset is critical to ensure the tankless water heater functions properly.

You will notice a light when you look at the tankless water heater. It is essential to pause for ten seconds to allow your tankless water heater to reset. You have completed the task if the light transitions from red to green. After the green, wait 10 seconds before moving to the next step.

If the indicator does not switch from red to green, it is advised that you contact a plumber for help. A bigger issue may need their attention.

6. Change The Thermostat

The thermostat’s temperature on a tankless water heater may differ according to the type. Many such heaters come with a knob that can be adjusted to control the thermostat’s temperature.

Find the dial on the thermostat and rotate it in the direction of a clock.  Rotate the dial to its top position. Once the dial is in its most clockwise position, this signifies the highest setting.

Make sure you don’t overlook the ten-second waiting period. This allows your tankless water heater to reset itself.

7. Check For Power Outages In The Home

The tankless water heater may signify a more substantial power issue. Look for other power cuts in your place. You may have only obvious electrical problems with the tankless water heater.

Examine the circuit breaker and determine if any switch is in the off position. Change the settings of any switch that is off to bring back power to all of the units.

If the techniques mentioned are unsuccessful, it is time to contact your plumber. Plumbers are well aware of the usual problems with tankless water heaters and are thus in a great place to assist with the difficulty.

This is how to reset tankless water heater.
