GE Profile dishwasher PDw8200 fills/drains continuously
by HORST REICHELT
My GE Profile dishwasher fills and drains continuously and thus never starts the wash cycle. I checked the flood valve which seems to be ok. How do you check the float switch on this machine?Need A Part Start Here

As far as I know the flood switch isn’t going to cause this problem on this machine. I don’t know for sure because right now I can only find a wiring diagrams for a PDW8900, witch is basically the same only the 8900 has a smart dispense so I think the wiring is the same.
If the drain pump is being activated during fill more than likely you have a stuck relay on the main board.
If the drain pump is not activated but the water is still draining it is somehow siphoning out. This is impossible if the drain is connected to the sink but if it is connected just to a drainpipe this could happen. If this is the case you need to install an air gap or connect it go the sink. This is very rare with dishwashers but possible.
I will try to find the exact wiring diagram for your model and if there is any difference I will leave a comment.
