This is used for the check valve.
This part works with the following brands: GE, Hotpoint & Kenmore.
This part fixes the following symptoms:
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.

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
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.
Took off the back screen, 4screws. Unscrewed old piston assembly. Put in new piston assembly, put screen back on. That was all there was to it. Now it drains just fine. I also added 2wheels to the front lower tray.
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.
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...
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.
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.
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!
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,
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.
ordered and received parts. unplugged electricity and drain and water supply turned dishwaser upside down for ease of access. removed clamps usin 1/4 and 5/16 nut drivers and phillips head screw driver to undo bracket clamps old parts and replaced and as per directions using two pair of adjustable pliers one to hold motor shaft and other pair to remove cutting blade. replaced impeller and blade ttaking care to keep track of screws nuts and bolts and older parts to make sure of assembly. turning dishwasher upside down makes for easy parts instalment. PAY CLOSE ATTENTION TO DISASEMBLY AND PUT TOGETHER IN REVERSE ORDER GOOD LUCK parts ordered to replace solonoid kit as it feels hot and still have burning bakelite odor.
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.
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.
