Welcome to our forum.
Agree with your last paragraph Tom! As I can run everything at 1 time,and nothing trips,it's telling me there's a prob in the cleaning cycle circuit.I replaced the heater board. There was no soldering involved,just put the wires back where they were.I'm wondering,if a relay etc in the cleaning circuit fried,on the main board,which is an IQ 2020 board?
That doesn't make sense to me. I can't imagine everything running fine separately but tripping the breaker in the clean cycle only. The clean cycle is a software program to run the hardware.
