Hot water TOO HOT~~ouch!

Motor Home, Georgetown 2012 (bought new in Dec 2011)

Hot water is way TOO HOT when using electric--literally burns your skin. We usually use gas when dry camping and both on shore power and turn both off when sleeping. Recently on shore power we forgot to turn off the electric and the next morning the pressure valve popped off and water was running down the side of our motor home.


Got any ideas or helpful suggestions? I'm pretty handy at fixing things.


Thanks for any help.
Doug

Sounds like your AC thermostat is malfunctioning. It should shut off via the high limit bellows and turn on via the low limit bellows.

I think your high limit bellows has a hole in it and is not opening to remove power from the heating element.

Assuming your water heater is a Suburban:

Replace the one you have with: Suburban Water Heater 130 Degree Eco Thermostat 232306 | eBay

It is an easy repair (one nut and two wires); just make sure to open the AC breaker in the power panel.

Doesn't really matter. Sometimes things just break.

My guess is you will find out (please take a photo) when you remove the rubber reset button cover.

Just turn the cold water on with the hot, takes less hot water. Doesn't do anything about the popoff
