Question MH: Hot Water Heater

In my 2000 39z Bounder, I believe I have an Atwood hot water heater. I have the electric/propane version. It used to heat automatically when plugged into shore power and on our last trip it did not while on shore power, however it works great on propane. The only switch I have is to make it heat via propane, otherwise it would heat via plugged into shore power. Anyone have this issue? Also, on the heater itself, there is no switch to go between like on a travel trailer.

I would still think that there is another switch somewhere for the electic side of it. Most setups would not want a load like that just to come on when plugging the coach into shore power. If you were to dog bone the shore power down to a 15 amp. plug you would be close to tripping it with the electric hot water heater on.

In addition to the "other" switch mystery location, consider checking the breaker in the main service panel.

When you winterise, the tank is empty so you certainly wouldn't want the electric element on then (although it doesn't matter so much if the propane is operated). It must have a switch somewhere.

If you you have drained it and had the shore power connected then it is very likely you have burned out the element.

You definitely have a switch for the water heater electric somewhere. Atwood doesn't provide a customer-accessible switch on the heater - it is normally located inside the RV somewhere. You probably had a Suburban brand heater before - they have a switch on the tank itself, where it can be reached by the owner.

Agree with the above that there is a switch somewhere inside the coach. The heating element is very quick to burn out if it is turned on when the tank is empty. Chances are good this has happened. The elements are easy to replace and easy to find in stores like Home Depot.

Yea I can't imagine it coming on automatic without a switch, I have a gas and electric switch. If the electric is on with no water it will burn out quick that maybe the problem.
