GE stops running anytime it has to fill with water

I have a year old GE GDT645SYN0FS. It started flashing H2O mid-cycle and would stop washing. Eventually it wouldn’t wash at all, it would start to fill and not even get enough water in to cover the bottom of the machine at all. I pulled the ultra fine and fine filters, checked the valve seal underneath. I pulled the spray arm and cleaned out the orange ball. I checked the water hoses for kinks. I replaced the water intake valve. I realized that if I put water into it to start, it will start running but the moment it has to drain and add more, it H2O’s out on me again. I’m out of ideas.

Hi @jyoumans14 ,

Presumably the dishwasher’s water supply temperature and pressure are OK - temp 120°-140° F, water pressure 20-120 PSI

Don’t know but was wondering if the problem is with the pressure sensor assembly, part # 333 in the Motor, Sump and Filter assembly diagram.

This is usually used to prevent the dishwasher from over filling but maybe it thinks that it is already full enough and stops it from filling further. You should get a different error code if it is faulty but maybe still worth looking at

According to the supplier in the link above the part number for the mini manual (service manual) for the dishwasher is 31-4000206_v10.pdf

This shows how to get into the diagnostic mode for testing but it also shows the connections for the pressure switch so maybe you can test it with an Ohmmeter (and the power disconnected) to see if it is working OK.

Hopefully this will be of some help.

Thanks!

I’m not getting any error codes. I am starting to suspect water pressure may be playing a part. On occasion, our house will randomly have low water pressure. It’s usually not low enough to be a problem, but if I run the faucet on when I turn the washer on, the dishwasher will go through the first cycle but stop when it needs to refill.

Maybe you can get a cheap water pressure gauge (example only) and check the pressures at various outlets around the house. You may have a restricted or blocked pipe.
