Remove the back filter to access check valve assembly. Twist check valve assembly to remove, not significant deterioration of rubber cap. Install new assembly. Re-install filter. Super-easy and effective!

remove the screen at the back bottom of dishwaser. (4 screws). Unthread piston and and nut assembly for check valve....thread in new one.
Problem solved....no more water $10 part....no repair person !!!

Remove shield in rear. Unscrew valve using hand. Screw new valve in place.

Removed 3/4" rear wheels from old damaged rack and installed them on new rack. Works fine now. For the price paid for this replacement rack, wide wheels should be included as part of the replacement package.

First let me say, it's so easy even a caveman can do it. I removed the water out of the bottom. Then I removed the cover in the very back of the machine with a wrench. As soon as I did that, I could see the piston. Next, I twisted the white piston out with my fingers (this was the hardest part). I could see the piston had partially disintigrated. I ordered a new one, had it delivered in a few days, and put it all back in reverse. It took minutes. Thanks to the guy that posted his story, I was able to fix mine for $18.

First I opened the dishwasher and removed the lower basket. Next I removed the 4 screws that hold the food filter plate in place at the back of the tub. Then I unscrewed the Piston/Check Valve assembly counterclockwise, located at the back center of the tub, by hand. I replaced the old part with the new one and reinstalled the filter plate. I ran a rinse cycle to verify that that all of the water was purged. Finally, I reinstalled the lower basket and resumed using my dishwasher.

Ordered door seal and followed directions included with the seal. I did put the seal in the clothes dryer for 5 minutes prior to installation as recommended in the Parts Select video that is posted on You tube.

I Just Open Door And Put Fill Cap In And Turn That It

removed screen at back of dishwasher from the inside. Twisted piston & nut assembly out by hand and replaced with new one. Very, very simple. Dishwasher works perfectly now.

As per instructions from this site I simply unscrewed the entire assembly and installed the new spray arm assembly. The old unit was a bit stubborn due to age so I used the long handle of my favorite screwdriver, inserted through the bottom area, for leverage. The entire process took less than 5 minutes. Very simple and as a side benefit, the dishwasher operates much quieter than before the old spray arm broke. Guess the old arm was also worn out before it broke on this 18 year dishwasher.

Unscrewed bottom of spray arm support assembly counterclockwise by hand for removal. Inserted new part and screwed it in clockwise by hand for installation. Worked perfectly. Video was helpful.

Removed filter/screen by unscrewing 2 screws with a nut driver and then unscrewed the old Piston and Nut assembly and simply screwed in the new part. Problem solved and my dishes are much cleaner and the water is draining out completely. Easy fix for this frustrating problem.

TOOK THE RACK OUT OF THE BOX AND PLACED IT IN THE DISHWASHER, DONE.

First I removed the bottom dishwasher rack. Using a 1/4" nutdriver I removed (4) 1/4" screws from the drain cover that is inside the dishwasher all the way in the back. This will allow you to get to the piston and nut assembly which was easily removed with no tools by simply grasping and unscrewing. Used a wash cloth to wipe "gunk" from around the threads. I then screwed the new piston and nut assembly in place. Used no tools to tighten, just "snug up" by hand. The seal on my old piston and nut assembly was 50 percent gone, not sealing at all. I guess the years had taken their toll. This solved my problem. The dishwasher washes and drains as it should. Super easy fix. Took me about 10 minutes to do the repair.
