Whirlpool WPW10348269 Drain Pump OEM Part

I've opened sump housing to check for clogging but it was clean. When I removed check valve to inspect it I've found out that the round part of the valve was missing so I figured it might've blocked the water exit at drain hose or something like that. So I pulled the dishwasher out to get a full access to drain hose connector and the pump. Upon disconnecting the drain and checking its connector I indeed found the round piece totally blocking the hose and acting as a seal. I removed the piece with pliers and installed replacement check valve. Since I've ordered a newer and better pump I also decided to replace it. Now my dishwasher works like a brand new.

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.

I replaced the pump drain. My assumption was that it was to weak. Whenever the dishwasher stop draining, I had to take a shop vacuum to clear to pump and the drain line, then it worked for a week or so, then repeat. Replacing the pump did not require any tools, or moving the dishwasher. (You will need a screw driver to remove the bottom panel - a flashlight might help too.) It was extremely easy, as long as you can lay on the floor to do the work. First make sure ALL the water is removed with a shop vacuum. Have some towels ready in any case. Disconnect the power from the washer (cut the breaker). Remove the bottom panel (two screws). The pump is centered right in front next to the water supply. Notice at the orientation of the pump and compare to the new. You will see which way to twist the pump to remove it. Reach in and twist the pump. It will then come loose from the mounting (no tools). Mop up any water. Un-clip the two wire plug and put the old pump aside. Move the new pump into position. Clip in the wire plug. Push the pump into place and twist in the opposite direction to lock snug into place. Turn on the power, and run the dishwasher and check for leaks. If all okay, position and screw bottom panel back in place. You're done! Now the new pump does have three bolt/screw holes, but on my dishwasher, the old one did not have them, so they are not used or required on my model.

Removed and replaced drain pump, drain hose and check valve. Very easy job and especially with the videos on the web site. I've been telling all my friends how easy it was and sharing the web site address to help them in the future. Highest recommendation I can give for this company.

After thinking about the problem, and not wanting to pull dishwasher out of the cabinet again. I examined the drain hose at the sink, and discovered it clogged. After removing the clog, and blowing on the hose, water started to drain. I am a happy camper now. Parts will be stored for next time.
