G man It sounds like you know alot about the powerclean machines. My temp guage on power clean was tapped out and shut down motor. The kohler mechanic bypassed shut off. The water heated up just fine. I replaced temp guage and the guage doesn't read anything and the water doesn't heat up. When i turn thermostat down i can hear it click. Is one of the wires on the back of temp guage be hot? Your insight would be greatly appreciated!
