Whirlpool WP8268340 Dishwasher Spray Arm Bearing OEM Part

My discharge would not empty after a wash cycle and I always had gross gray water left in the bottom approx 3" deep? After doing the obvious things of checking the simp for garbage, and checking that the discharge hose wasn't blocked, I removed my discharge pump ( not too hard to do) and tested. My pump which did run and turn the impeller. However, the pump evidently had weakened with time and weakened and could no longer pump the waste water up hill to the "T" connection under the sink. A new $65 pump remedied the situation and saved me from buying a new $600 dishwasher! The install of the new pump took approximately 1 hour. The only tools required were some screwdrivers to remove the door panel (for working room) and the valance at the bottom of the machhine and remove a hose clamp; everything else came apart with locking plastic tabs.

Replaced the upper spray arm seal

I want to thank those people who wrote their story about their dishwasher. My Kenmore dishwasher stopped cleaning the dishes and left a film on the dishes. Also the top shelf hardly had any water to it when the cycle stopped. My soap dispenser would not empty completely. The soap dispenser on the door would open ok, but at the end of the cycle there was still 1/3 of the soap left in the dispenser. I ordered the Chopper Assembly, replaced it and my dishwasher works like it did when it was new (its 13 yrs old). Also thank you for the very good video on how to replace the Chopper Assembly. I am a very happy customer!

The old sprayer hub had worn to where one side was worn through and the other edge was still almost as thick as the new one. I think the sprayarm bearing had worn through at some point and was no longer providing protection between the moving parts. I replaced both parts and the dishes seem to be much cleaner. Another forum mentioned that water pressure could be lost through 'gaps' like that and cleaning would be effected. I also had to clean soap scum out of some of the ports on the middle spray arm. This allowed the arm to spin better during cleaning. Another item I replaced was the spray tube that goes up the back of the tube and has the flapper valves for the center rack in it. Those had become calcified and would not close anymore allowing water pressure for the center spray arm to be lost. Replacing the flapper valves seemed to help with cleaning as well. Dishes come out nice and clean now. I also fixed a minor leak near the front right-side of the door. I had to tighten the large plastic nut that holds the float assembly in. It was about 3/4 to 1 turn loose and caused the leak. Tightening the nut cured the leak.

Fix went fine. Found a piece of a frying pan handle lodged under the accumulator assembly. Removed and noise fixed. Your video was extremely helpful in showing exactly how to disassemble without damaging various plastic parts!
