ParticipantDoes it continue to fill when the power is removed? If so the Aquastop valve is faulty. Otherwise as Dave says, it’s a board fault. Graham

ParticipantIncidentally, I like to force a bit of water through the hole where the little pressure switch connects (Length of rubber hose and a syringe!) just to make sure that the pathway is clear into the sump. I’ve had the air reservoir clag up, reducing or blocking ability of the pressure switch to sense the water level.

ParticipantI have similar but it fills and drain, when you quickly open the door, you can see the water spout from the airlock chamber and it stops. I can’t locate pressure switch, I am rather annoyed that I can’t seem to feel it or locate it. What is worse that the dishwasher is less than 6 months old and the owner didn’t register the machine (I supplied the dishwasher, installed it and told the customer to register).

Participantthe most common cause for overfilling is the pressure tank getting blocked with grease.
they can be a pain to clear out as the pressure biottle is welded into the sump but with a flexible bit of wire / hose you should be able to clear the pressure bottle.
It only takes a little bit of grease to block them, rubbish design. -
