We have a one year old electric hot water heater at our lake cabin. Last week the circuit on the tank tripped for some reason and needed to be reset. Now we get water that is really hot and I can’t regulate it with the thermostats (upper and lower). I set them both to around 100 deg. but the water coming out is much hotter than that (too hot to touch). Possible thermostat problems? If so is that a separate component or part of the element?
