Water Heater Problem

The water heater on our Catalina has stopped working. I noticed that the water heater trip switch on the nav station pops out everytime I push it back in. Any suggestions as to what I need to be looking for would be greatly appreciated. Maybe the trip switch needs to be replaced or could the problem be something else?

More likely your element is shorted and trips the breaker when you try to use it.

I would assume the water still gets hot when you run the engine (if you have that capability?)

Thanks for the reply. The water is supposed to get hot when running the engine. I haven't tried it out since I figured that was an independent system that would not use the element. Is there an obvious way to know if the element needs replacing?

Faster's diagnosis is most likely the problem IMO as well. You can test the heating element for a short by pulling off both wires and using a multimeter to see if there is continuity to the tank (closed circuit) I think the most likely cause of a shorted heating element is sediment that builds up on the heating element that gets thick enought to start touching the inside of the tank. You may be able to confirm that as well by screwing out the heating element and seeing how much crap as grown on it. Might be able to scrape it off and get another couple weekends out if it before the new one comes in. (at least that's what I would try)
