So, I go to shower, no hot water. Head down to basement, check water heater and breakers. I found that one of the breakers in the breaker box had blown, and the breaker at the element itself had popped out. I clicked it in, reset breaker, and now I have hot water again. I also noticed water on the floor that looked as if several gallons had come out of the overflow/overpressure on the top of the heater. I'm guessing the top thermostat didn't shut off and it overheated, causing water to come out the overflow, and the breaker to blow. Does this sound reasonable?
Now it's working, but for how long? Those of you that know more then I do about water heaters (which is probably most of you lol), would you replace the thermostat for the top element (is it part of the element, or seperate?), or watch it to see if it happens again?
