GSB2800E*119 General Electric Dishwasher - Instructions

Looked online for a general cause. ABout 60 to 80 percent, the cause was the piston and nut assembly located in the back of the dishwasher. Ordered the part and installed in nothing flat. Only four nut screws to remove the take the filter off and unscrew the piston and nut assembly. Next cycle, no water and the drying cycle seemed to be better. Guess because no water in the bottom of the dishwasher. Good input and fast turn around on the part.

Remove the screen that runs along the back of the dishwasher.In the middle of the area that was covered with the screen you will see a white plastic valve with 2 little ears sticking up. Use the nose of a pair of pliers to twist counter/clockwise on the valve and it will come right out. Inspect the valve.If the rubber cone shaped valve inside the valve can be pushed through the top of the valve ,the valve is bad.Replace it and go wash your dishes.

Had to pull off the front cover where my problem was. Discovered a burnt out switch of some sort, looked it up on your site and found the part. It seemed expensive so I searched a few more sites and discovered you had the cheapest price. I ordered the part on Monday morning and used the cheapest shipping. 5 to 7 days is what i was informed of so i figured it was worth the wait. I got home from work Tuesday and the part was at my door (wow!) I still had my dishwasher torn apart so I put the new part in and about ten minutes later I was washing a load of dishes! I would refer partselect.com to anyone. Thank you! I hope I never need to use your site again but if I do I've got it saved in my computer! (-:

I put on my rubber gloves, removed the lower wash rack, removed four screws from the drain guard. I unscrewed the defective part, installed the new assembly and hand tightened. Replaced the cover and installed the screws removed earlier. Re installed the lower tray, and ran the rinse and drain cycle. It has been working beautifully ever since.

Partselect was the only one that had the correct solution. The Piston and Nut assembly fix the problem. The washer on top of the piston was worn and it would not fully close. Replace the piston and nut assembly within 15 minutes after I found it.Shipping was supposed to be within 3 days. The part came the next business day during the thanksgiving holiday. WOW

i unscrewed the 4 screws in the back, took off the guard thing, and unscrewed the existing part with my hand. put new part in and ran dishwasher. the part did not fix the problem, now i'm on to maybe replacing solenoid? i have no idea. this part was simple to replace though. hope i can fix this issue, i need my dishwasher to run right!

remove the four screws in the back of dishwasher on the inside. Remove screen. Remove the piston nut assembly for the check valve. Re-install the screen and four nuts and your done.

After running a test cycle and realizing the pump was working but not pumping all the water out, I checked the troubleshooting guide and parts list.
I found there was a check valve at the back of the machine and when I removed it I saw it was split causing the water to return into the unit. I ordered and replaced the check valve and the unit is back in perfect operation.

Replaced the Piston and Nut Assembly, located inside the dishwasher under the screen at the back, by unscrewing the old one and replacing with the new - Works great now!!

removed piston in filter and replaced. the check valve had come apart and was not sealing

First I removed the four screws from the screen/cover located at the back of the dishwasher. You will notice a mesh screen in the center of this cover. The check valve is under this cover midway between the sides. The check valve is unscrewed counter clockwise. I had to use a pair of pliers to start turning the valve. There are two "ears" on the top of the valve. You will see a rubber cone shaped piece that should completely cover the opening when the plunger is depressed. In my case the rubber was almost completely gone allowing water in the drain hose to return to the dishwasher after the drain pump stopped. The new check valve threads back into the opening and should be finger tightened. Replace the cover/screen and you should be good to go.

Assistant helped me take apart unit, assumption on issue was correct, part was ordered and showed up 3days later. I installed and all seems fine. I do question what would have happened if the deduction was incorrect. The assistant was very patient and clear with his instructions. A good experience!

I reinstalled a new piston/nut assembly which was easy as per this forum. The two compared side to side clearly showed my old one as worn out and deteriorated. This however wasn't the only problem. Once new piston/nut assembly was installed the water still did not drain. I pulled the dishwasher out from the cabinet, disconnected the hose connected from the pump to the outer box the piston/nut assembly connected to and flushed that out. I discovered two pieces of broken glass in the box that may have been blocking the rubber flapper connecting the box to the drain hose. Glass was removed and once all was reconnected the unit drained perfectly. Check for potential debris in outer piston/nut assembly piece if simple change out of of piston/nut assembly doesn't solve the issue.

I went to PartSelect online and easily found an exact duplicate of my old basket at a reasonable price. I ordered it, expecting delivery in about 3 - 5 days. It was on my doorstep 2 days after the order was placed. I opened the dishwasher door, set it in the place of my choice, and what a timesaver! Try it! You'll like it!

Took of the plactic strainer shroud unscrewed the piston nut assembly by hand installed the new one it takes longer to remove the shroud than it does to replace the part
