GE Triton XL Dishwasher Will Not Drain

Model numbers starting with GSD, such as GSD6660G00SS.

Most “no-pump-out”? issues are solved by cleaning out a plugged air gap, drain hose or disposer. However, on GE dishwashers with a rear filter, “no-pump-out”? may also be caused by a malfunctioning piston and nut assembly, located underneath the rear filter. To save time, effort and repeat service calls, always inspect the piston and nut assembly when diagnosing a “no-pump-out” complaint.

The piston and nut assembly has an integral check valve, shaped like an umbrella, which closes the collection chamber inlet during pump out. If the check valve is damaged, held open by debris or assembled upside down, water will circulate inside the tub instead of going down the drain. Cleaning a clogged valve or replacing a defective one will solve the problem. This check valve is very inexpensive, especially given that it’s a GE. Come git you one.

If the piston and nut check valve assembly is functioning normally, verify operation of other parts of the drain system. Those parts include the dual pump check valve on models with a three port collection chamber, the adapter check valve at the outlet of the collection chamber, the solenoid/gate valve mechanism on the main pump and both the main pump and dual pump, if equipped.

    This repair advice was a great help. Our dishwasher hasn’t been draining completely for some time and had recently gotten worse. I located the check valve and the rubber garket had completely deteriorated. I ordered a new part today, but I decided to see if I could get the old part to work while I’m waiting for the new check valve to arrive. I bought a 5/8″ beveled neoprene washer at my local hardware store for 69 cents and put it in place of the original. It seems to have completely fixed the problem. So if anyone else has the same problem with just the rubber gasket being damaged, you might be able to fix it really cheap.

    Thank you so much Mr. Samurai fix it man! You saved the day. I will recommend you to everyone (…and GE to no-one). I went to GE’s worthless website FAQ’s and got no advice on my GE Profile Trition quietpower III GSD5940F00SS dishwasher. But after reading the on-line complaints, it is obvious that this is a common problem related to GE’s design flaw. Modern dishwashers should not succumb to drain problems like this one. After getting quotes of hundreds of $$ for someone to even talk to me about this problem, I was about ready to fork out another grand for a new DW (GE not on the list). But your article was right-on. A 1 hour do-it-yourself fix for very little to no cost. Thank you for this service.

    Have a GE Quiet power 1 which started to not drain properly here and there… and ultimately (yesterday) stop draining completely. Followed the instructions of this post… the rubber “seal” of the check valve was dead, bought a new check valve ($12 CDN)…. put everything back together, and THE PROBLEM IS FIX!!! A little over an hour which includes the time to get the part!

    THANX Samurai

    A little side note…when I walked into the part shop, I just held up the part, and was about to say something, when the clerk simply glimpse at the part from about 5 feet away, and simply said, ” I get the part in the back”. Guess it was not the first time he saw this ! 🙂
