My GE Dishwasher which is only 5 years old is not draining. I have checked the drain pipe itself and it’s clear because I can put a shop vac on the garbage disposal side of the pipe and it will suck the standing water out of the washer. Thought it must be a bad drain pump so I replaced it. Still no luck. Any suggestions? Wondering if it’s the main control panel. It’s runs fine thru the cycle just won’t drain.
