GMC680X* General Electric Dishwasher - Instructions

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.

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.

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.

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

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.

Removed the 4 1/4" screws holding the rear screen to the bottom of the inside of dishwasher. "Piston & Nut" assembly was badly corroded- to the point that no dirty water was leaving the dishwasher. Because the appliance is at least 10 yrs old and there was nothing happening during the rinse cycle, I initially assumed the worst- that the pump was bad. After reading the other descriptions of the problem here, I said, "what the hell?, if a $20 part fixes it, I'll be amazed- if not, I'm out $20 and looking at another $300 for a new dishwasher!" The $20 part (inc. shipping) did the trick. Thank you, and your website is on my "highly recommended" list! One note- the piston & nut assembly did offer some resistance as you might expect after being "gunked" in place for 10 years. However, the top has some lugs or ears built into it, so a few taps with a hammer on my largest straight-blade screwdriver loosened it right up...

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.

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.

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

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!

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.

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