clicking - water heater
When I turn on our Atwood water heater to electric, the converter clicks about every 3 seconds as if it is turning on/off. The w/h is definitely 110v and the breaker is not tripped and we are plugged...

If 2004 or newer model that clicking is the DC Relay that closes to allow AC to the element
It is failing
DC Relay and element are inside that protective cover on backside of WH Tank
Never heard any of my RV water heater electric elements click or any clicking from an electric residential WH
Heard them 'buzz' from scale/calcium build up but no CLICKING
He has a 2015 model. The relay may indeed be bad. BUT, a way to test is to install a AC amp meter on the circuit and see if you have loss of amp draw during the clicking. AND, IF the clicking is at the BACK of the WH, then the relay would be suspect. IF at the front, then no. BUT, I would also test the YELLOW wire at the Circuit Board for intermittant 12 volts. That is the activation wire for the Relay. IF the yellow has on and off 12 volts, the circuit board is BAD. Doug
