Control-panel communication fault

Power the dishwasher off at the breaker for a minute, then restore and retest
Open the door outer panel and inspect the ribbon/harness at the hinge flex point
Reseat both ends of the panel-to-board connector and look for a broken conductor
Dry any moisture in the door wiring channel and check for corrosion
Swap the control panel board, then the main board, to isolate the dead half
Pro Diagnostic Tip
The door harness flexes on every open, so Ed on an older unit is most often a cracked conductor at the hinge — inspect the flex loop before ordering either board.
