I have a GE hybrid water heater that is displaying a message 'Wiring to unit incorrect (must be 240V not 120V) or a heat pump fault.' It has given an F3 code a couple of times and continues to beep. I have checked the voltage and it is 248VAC, which is fine. How can I make it stop beeping and put it into standard electric mode?
