When Do You Need To Reset The Dometic WH-6EA Water Heater?

A Water Heater Lockout requires you to reset the Dometic water heater. Lockout is a security feature added to the water heater in order to prevent accidents. Some common reasons behind water heater lockout are:

Thermostat Failure

A thermostat in your Dometic WH-6GEA is a part that measures and regulates the temperature. If the temperature of your water heater is too high, it won’t be able to function properly. A faulty thermostat won’t be able to regulate the temperature, and this creates a lockout situation.

No Ignition

Your Dometic WH-6GEA has two ignition modes. One is an electric mode, and the other is a gas mode. When one method fails, the heater will use another ignition mode. But if both are non-functional, the ignition lockout light will illuminate. 


Too much heat is bad for your RV’s Dometic WH-6GEA water heater. When the sensor detects overheating, it will try to regulate it automatically. But if the temperature buildup is too high, you will face a lockout! 

If you face this water heater lockout, you will need to reset the Dometic WH-6GEA water heater.
