GSD4940ZZ0SS General Electric Dishwasher - Instructions

replaced pump and motor with new one. worked but pump would not empty the water. ordered additional parts check valve,seal and box that check valve screwed into. did not fix problem. Got to looking at replacement pump and discovered thet discharge solonoid was not completely opening the discharge port. I could hold it down manually and the machine would empty. I reported the problem to parts select and they without question shipped me a new pump and motor. took the dishwasher out of the wall again and swapped them out, and now it works fine. the repair was easy and simple. the difficulty was taking the dishwasher out and reinstalling it 3 times. I will use parts select again if the need arises.

Originally replaced solenoid without pulling unit out, but continued to leak. Purchased the entire motor and pump kit; pulled unit out, turned it on end and replaced the motor. The only problem was that no new ground screw was sent with the kit and the existing screw wasn't quite short enough to connect. Either the hole on the replacement kit needs to be deeper or a bond screw needs to be sent that will fit the new kit. We had to find our own screw that would fit properly.

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.

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 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.

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,

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.

The part that took the longest was taking the washer out from under the counter. The fix was the easy part = 15 to 20 minutes no problems. After putting the washer back and reconecting everything,the first cycle I had some leaking around one of the two big clamps. I had to pull it out again and move the clamps around and tighten them. Much better the 2nd time around, Good to go!! HAPPY WIFE HAPPY LIFE !!!! Good Luck !!

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

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.

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

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.
