Customer Question

can I wire a whirlpool electric water heater to 120V? model: ee3j40rd045v
I know the unit is for 240V.....but I only have 120V. I also know at the lower voltage the heating time would be lowed by 50%.
I'm worried about the electronic controls

Hi there,

yes it is possible the only issue is it will stay on much longer and take 4 times as long to heat the entire tank to set temperature not half as long, plus wiring it up like that will void any warranty you may have on the unit, other than that it will be fine.

I understand that the heating elements are okay with 120V but I was concerned about the 'smart' electronic panel. If it operates on 240V will it function compatable with 120V? I suppose I can try

Well the voltage is not gonna damage the board but, the board may error out and not allow the unit to operate if the board detects there is not enough voltage present and seeing it is a 240 volt system it may just do that but it would not damage the board.
