The Tank › Water heater immediately trips GFI as soon as it is reset › Reply To: Water heater immediately trips GFI as soon as it is reset
Hello: I’d suspect there is a leak to ground in one of the heating elements… probably the lower one. You’ll find discussion of just how to check with a meter in some of the other posts on electric heaters.
It isn’t the norm to have a 240 volt heater on a GFI. Calling an electrician might not be a bad idea.
