Whirlpool 8269144A Dishwasher Drain Hose 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.

I figured out that it was probably a plugged pump hose, since the pump would run, it somtimes it drained and sometimes it didn't. Your video helped with how to take the dishwasher out and replace the hose. I replaced the hose and everything is now working fine. It turned out to be a broken check valve in the old hose that caused the problem. It took 90 mins to do the repair.

Replaced with new one.

Check the hose clamps before ordering the sump! I called to talk to a pro and they suggested buying the sump as well as the diverter motor, which I did. While removing the motor from the old sump, I had to destroy the old hose clamps that were on the small hose connecting the sump and motor. The clamps that were on my Kenmore were compression clamps, not the type with a screw. I checked Lowes, Home Depot and a local hardware store and nobody carries a large enough clamp with that small of a width. So, I had to stop in the middle of fixing my dishwasher to order the right clamps (part # AP5971447). I haven't been able to finish yet because I'm still waiting for the clamps to arrive, but I was able to get the new sump installed without any problems. The how-to videos are excellent.

I watched the video here and it looked pretty simple, so I ordered the pump and received it the next day for only $10 shipping. The repair went smooth as glass, just like the video and had it done in about thirty minutes.
