Where is the RV Water Heater Reset Button and How To Use It?

No one likes overheated water in their body or daily usage because it can burn your skin and cause a problem with the water heater. RV water heater is no exception. Sometimes, your RV water heater’s thermostat malfunctions, which is why a reset button exists for that purpose.

Different RV water heater reset buttons are located in other places, but almost 90% of them are behind the thermostat panel board, and it is a red colored button. You need to press and hold it for a few seconds until you hear the water heater starting again.

Some people find it hard to locate that reset button, which is evident because even I faced the same problem. But don’t worry, stick with it to learn how to identify and use it.

Reasons That May Trip Reset the Button Of the RV Water Heater

Modern RV water heaters include a reset button because there can be malfunctions like the water is too hot or not hot. Old RV water heaters didn’t have a reset button, which caused many problems and had to be reset manually.

There can be several reasons your RV water heater reset button keeps tripping. You need to know why this is happening so you can fix it.

Let’s examine the most common reasons for RV water heater reset button tripping.

Inside Water Temperature Got Too High

RV water heater shuts off the power when the water temperature rises to the desired level. But, sometimes, because of some malfunctions, it can fail to stop, which results in extremely hot water, and to prevent from causing any accidents, the reset button trips and stops the heater.

Broken Thermostat

Thermostat is the device that allows you to set which temperature you want your RV water heater to heat the water. A faulty thermostat can fail or excessively raise the temperature, and then the reset button trips to warn you.

Faulty ECO ( Energy Cut-Off)

It happens rarely. Still, the ECO or energy cut-off mechanism of the RV water heater can be faulty, which fails to turn off the heating after reaching the given temperature. This is another reason for reset button tripping.

Wiring Issue

Wiring issues like power connection wires or control panel wire can be worn, which result in sparks. As a result, the RV water heater fails to start, and the water stays cold. Reset button will trip unless you fix it.

Defective Heating Elements (Burner Defect)

RV water heaters mostly work on gas, and that gas needs to be lightened. So when a burner fails to ignite the gas, the reset button trips. It can happen because of rust on the burner.

Ran Out Of Gas

This is unusual, but sometimes the sensor fails to detect the gas empty, especially on the older RV water heaters. The water heaters continuously try to ignite to heat the water, but when it fails, the reset button trips as an empty gas alert.
