GMC680X* General Electric Dishwasher - Instructions

Remove old piston assembly with screwdriver and tapping hammer inside the machine and screw the new part in hand tight, all done works fine

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.

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.

first I removed the screen in the back of dishwasher and then I replaced the check valve

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 read the reviews on line and followed the advice the part was easy to find and easy to replace once I got the screen off it came right out with a twist. and right back in reverse order, I fired it up and it drained, yay! no more stinky mess and no call to the appliance repair guy,

After researching for a few minutes on this site I was pretty confident that the problem I was having was a faulty check valve. I removed the 4 screws holding the cover in place at the back of the dishwasher tub, twisted out the check valve and saw it was obviously shot. I ordered the correct part and 2 days later I had the dishwasher working like new. Installation was a simple as could be....twist in the new valve and reinstall the 4 screws.

No story just locate partselect.com on internet, select part and order. Part received in a timely manner in great condition. Thanks

Once I found out where the pison was it was easy. I removed the far back screen that runs across the entire back of the inside of the dishwasher. There was four screws to remove this screen. This exposed the Piston assemply which is threaded, so you just twist it off like a big nut. It was easy to tell that the rubber on the piston was not sealing and needed to be replaced.

Followed the directions from the website and removed the plastic screen from the back of the washer (4 bolts). The Piston and Nut assembly was easliy removed with a few turns, popped the new one in, and re-installed the screen. Everything works great.

follow instructions found here, with a little help from part diagram. Initially removed the sump cover but then removed the cover at the back of tub. This uncovered the Piston assembly and the replacement was a snap. Dishwasher now works well and actually cleans the dishes. Also did I mention my parts arrived the day after I ordered even though I used standard delivery. This site rocks.

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!

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!!

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.
