Water heater

[Hubert wells]

Getting my 08 Monaco diplomat ready to go the the Monaco gathering,   yesterday I checked the water heater and it keeps kicking  the bedroom 20 amp breaker.

I switched breakers but didn’t help.

I put new heating element in also. It works good on gas but not 110 v. It’s a Atwood water heater .

Any suggestions what to check next ?

If it trips immediately start checking connections on that line. Maybe a wire came loose at a receptacle or a wire nut in a junction box. Good luck

Thanks , it does trip immediately.

We have an 08 Endeavor so should have the same layout basically.

The water heater plugs into an outlet near the heater. Unplug from that and see if your breaker trips immediately again. If so, the water heater is not at fault and you will have to work backwards from that. 

If it does not trip, follow the power cord to a black box on or near the water heater and open it up for inspection.

A 12 volt relay controls the 110 volts to the water heater.
