I am referring to the red fault light coming on and heating stops. I can shut the heater off and when the water cools, it will start heating again. System always heats until it faults. I have not tested the temp but it feels very hot
I ordered the T-stat and ECO kit. This seems like the 1st step.
Thank you all for the input
