My neighbours dishwasher filled up so that when she opened the door there was a few inches of water ready to flood her kitchen floor.

I reckon it is a sensor fault. I dug about on the internet, and it suggests it is a flow meter that tells the machine how much water is in there.

How does the flow meter tell how much water is in there?

or I am barking up the wrong tree?


The ones I've fixed have a lever sensor which works on air in a pipe
pressure they have a pipe from the area where the water collects at the
bottom to a sensor which is usually round tucked away higher up in the
machine. If the pipe gets blocked the machine over fills and/or doesn't
empty correctly. Never seen a sensor fail it is usually a blocked pipe.
Same idea in washing machines.
