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.
Gene.
I cant figure this one out. Do you know why my new dishwasher wont drain either?
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.
Gene.
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: http://forum.appliancepartspros.com/dishwasher-repair/2903-whirlpool-dishwasher.html 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

Is there a trick to removing the inlet protector? It seems stuck
Thats what it says in the tech sheets: “Rotate screw-end of protector upward to remove part and expose chopper assembly”.

Thanks that worked. The check valve (#5 on the diagram) was missing the round part. I guess you find my problem. Do I order the part on line of would Sears have this in stock? Should I replace anything else? I did remove the dishwasher and it’s sitting in my garage
Thanks again - U da man
You are welcome.
The part number for the check valve is AP3152971and it is good in stock. You probably should have it Tuesday. I do not know where do you live and how far is a local Sears store from you.
I can not tell you if anything else has to be replaced. Probably not.
Keep us posted.
Gene.
Gene,
That wan’t the problem. What’s next?
Check the drain pump. Remove the drain hose and make sure it’s clean. Do not blow air through this hose into the dishwasher.
Gene.
P.S. Have you replaced the garbage disposal recently?
That was it.
Thanks
Check if you removed the plug in the garbage disposal for the dishwasher drain connection.
Gene.
I had the garbage disposal replaced and now my dishwasher doesn’t drain. I called the installer but he said they were unrelated. It seems too conincidental for that to be the case. Is there something I can check/do?
There is a plug for the dishwasher drain line in the garbage disposal which must be removed during the installation. Disconnect the dishwasher drain hose from the garbage disposal and check if it was removed.
