    Throwing the breaker

    I have not yet pulled the Hot Water Heater to investigate, But I am hoping to get some idea as to what is wrong. My HWH is throwing the breaker, and when I flip the breaker back on, I hear a buzzing noise and it immediately throws the breaker back off. On my last trip we had to run it on Propane, which works great. I have never pulled a HWH before so I really don't know what I am up against, Any advise or suggestions would be greatly appreciated. Thanks

    Your HWH element more than likely has a whole burned in it and has gone to ground. Replace element.

    Assuming you have a Suburban Water Heater, you don't need to pull out the entire water heater. The 120V AC heating element can be easily removed and replaced. You'll find instructions starting on page 9 of our owner-written Water Heater Troubleshooting Guide. Replacement elements are available at RV dealers, Amazon and other online stores, or even at most hardware stores.

    Re: Throwing the breaker

    One other thing. There is a junction box on the front, inside corner of the water heater where the 120V AC power from the circuit breaker panel connects to the water heater wiring. Occasionally there's a problem inside that junction box that can trip the circuit breaker.

    If you have a ohm meter it’s easy to check element condition before you remove it.

    Always make sure you have water in the water heater before you turn on the switch for electric.

    That is probably what happened...
