Hi Eric, Thanks for the explanation. I've checked continuity between the overtemp switch and that seems fine. I checked if it's getting voltage and it's only getting approx 5v. I also checked the pressurestat for voltage and the top connection and bottom connections are only getting a couple of volts, but the middle connection is getting 240v. There is 240v going to the brew boiler.
