Communication fault between main board and control panel

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