hi its a whirlpool dishwasher adg642/1 1x
8542 769 15889.
when you switsh it on the pump goes for 2 seconds and the start light goes on, then the pump stops for a couple of seconds and the start light goes off. it repeats this forever.
there are no flashing lights i checked the pressure switch, heater, motor, and ntc, there is no water in the base of the dishwasher,
i think it is the pcb any ideas welcome and part number for pcb would also be appreciated thanks.

Constant flashing is F1 – NTC failure.

Have you checked the wiring from the NTC to the PCB? If the wiring is open you get this also check the drive Triacs.
