One may also ask, why does my hot water switch keep turning off? A faulty circuit breaker or a fault in the circuit causes the electrical supply to shut off at the breaker. A malfunctioning thermostat acts as if the water temperature is at the desired setting, and does not call on the heating element to provide heat.

Beside above, why does my hot water heater keep tripping?
