I have a whirlpool quiet partner 1 dishwasher. The water will not drain completely during the drain cycle. I have to restart from the drain cycle again to drain the water completely. I have checked for restrictions in the drain hose and everything seems alright. Could this problem be the timer? The water does drain but I have to do it twice. Please help this thing is driving me crazy. The model # is DU920PWKQO
The first thing I would check is the air gap (if any) on top of the sink.
Remove the cover and the top piece and check for clog.
If there is nothing wrong then the problem is a clogged check valve (#15 on the pump & motor break down diagram).
Remove all water from the dishwasher.
Remove the bottom panel.
Remove the drain hose from the check valve (be prepared for some water on the floor).
Unscrew the check valve and make sure it’s clean.

Thanks Gene,
I will let you know how it goes.
Gene,
You are the best:)
That’s exactly what it was. I found 2 little plastic pieces inside the check valve and removed them. Now the water drains perfectly. Thanks for all your help.

I’m glad you were able to fix it.

Hi,
Have same problem and symptoms of above poster. Found a little bit of gunk at the end of the check valve but I find it hard to believe thats the problem.
One poster mentioned that the check valve unscrews…are you sure? There is a tag right around the check valve stating that the valve is not to be removed from the dishwasher.
Any assistance would be greatly appreciated - model DU915PWKQ0
Sorry it is a DU915PWKQ0, and I need the 4 screws that hold the bottom two plates on.
It’s taped to the lower washer panel inside or stuck to the inside side panel
Can you be more specific on the problem? What is the complete model number of the dishwasher?
Gene.

Hi Gene,
I had this problem draining and cleaning the one way valve fixed me right up. I just wanted to say thanks!

PS For anyone else doing this, the rubber valve flops outwards. It took me a while to figure out you can run a long screw driver right through the valve to clear the blockage, just do it from the small diameter exiting through the large diameter.

I purchased the upright Frigidaire commerical frost free freezer used. The guy told me his mother bought it last year but she passed away and he has no use for it. I think I got taken! There is frost/ice buildup along the top inside of the freezer. I’m not sure if its just the gasket or something more serious. When I looked for the model and serial number (WB41119021) I noticed it said it was made in 2004 so it appears he lied about his mother buying it new last year.
When was this thing made and what suggestions as to whats wrong and how I can fix it?
Thanks, P.K.
Paul,
Defrost all buildups and check how good the door is sealing. Put a dollar bill between the door and frame and check how firm it stays.

Hi Gene, thanks for the reply. I did try putting a dollar bill in the door today when I got home from work. I closed the door and the dollar bill slid out pretty darn easy. Door gasket?
Thanks again, Paul!
Gene communicating this way is still new to me. The bill stayed in place but when I pulled on it it slid out pretty easy.
Hi Gene sorry to bother you again but I wanted to make sure I’m giving you enough info and doing this right. The frost buildup is not on the gasket but the top inside of the door and the top inside of the freezer. Also the sides of the freezer are quite warm, almost hot. Is that just good insulation, not letting the cold out or is it a problem contributing to the frost buildup?
Paul,
Try to warm up the door gasket, using a hair dryer, and reshape it to make it sealing better. After you’ve done close the door and tape it tight for a few hours.

Hello Gene,
Thanks for the advice on the check valve, I couldn’t let this thing whip me and low and behold I found 2 fish bones and 2 lemon seed stuck inside. Pumps like it should now. Thanks a bunch once again Gene!!!
I’m having trouble getting range top open. I have already popped the clips on the side and top will only open about 1-2" I need to replace the ignitor switch
I have the same problem with my DU920PWKQ0. I have cleaned the check valve and hose. I ran water through the check valve and it flowed fine. It’s still leaving about an inch of water left after cycle done. I have gotten all the water to drain out but had to run drain cycle 4 or 5 times. I don’t know where to go next. Can you help?

Where is the drain hose connected to?
If it’s connected to the garbage disposal, disconnect it and check for any clog. Make sure there is no any floating foreign objects inside the hose.
If it’s connected to the air gap on top of the sink, most likely the air gap is clogged up.
