The Dishwasher does not drain. If Cancel/Drain is pressed, the motor runs but it still does not drain.

Hi Singh,

The first thing I would check is the air gap on top of the sink (if any).

Remove the cap and the top piece and check for any clog.

The second thing I would check is the check valve (#15 on the pump & motor break down diagram).

Remove all water from the dishwasher, remove the bottom panel, disconnect the drain hose from the check valve and unscrew it. Check for any clog.

Here are the break down diagrams for the Whirlpool dishwasher Model DU940PWKQ1 (basic model DU940PWK)

Good luck.
Gene.

I appreciate your help, Gene. The Check Valve was clogged. I cleared it, and the draining is working now.

I'm glad you were able to fix it.

I cant figure this one out. Do you know why my new dishwasher wont drain either?

[Gene]

In order to provide the most accurate advise I need the complete model number of the dishwasher and the most specific description of the problem.

if you have a minute to give me some tips, it would be very helpful to me.

my friend just called me and said her dishwasher sprayed the water out through the drain thing on top of the sink. I'm guessing her main drain line is clogged, i'm heading that way tomorrow, i was just trying to be prepared before i arrive because i have never worked one dishwashers before. she has Whirlpool model DU 8400 XB1. If you can give me any tips it would be great.

Thanks ahead!

Check the hose from the air gap to the garbage disposal for a clog. If the garbage disposal has been replaced recently then most likely it was installed improperly. The new garbage disposal comes with the plastic plug in the dishwasher drain connection which has to be removed at time of installation.

Gene,
I have a whirlpool gu1500xtlt3 dishwasher that also is not draining. The drain hose goes directly to the disposal connection. I can't tell if it is clogged but I blew into it and could here something from the bottom of the dishwasher / like bubbles.
Can you help me?
Thanks

PlanoRick,

Open the pump as described in one of our previous posts: whirlpool dishwasher and check the check valve (#5 on the diagram). Check the drain pump.

Here are the break down diagrams and the parts list for the Whirlpool dishwasher Model GU1500XTLT3
