Whirlpool Dishwasher model DU900PWKQ0 only drains when water level is low in dishwasher

5 posts in this topic

Hi I have 10 year old Whirlpool Dishwasher model DU900PWKQ0. It loads water in fine but will only drain the water when there is just a small amount of water in the bottom Once the amount makes it up to the door, it wont drain. It drains fine when the amount of water is small but does not drain at all otherwise. I checked the check valve and replaced it, I also opened up the inside all the way down to the food chopper and cleaned it out. I checked the float and the Float switch. All are fine. I checked the hose and also ok as I noted when the amount of water is small in the dishwasher it drains fine. Any further thoughts on this is appreciated.

Check the check valve (where the drain hose connects to the pump). You may find some debris in there...

Thanks as noted I checked and even replaced the valve and did not help.  I also opened up the inside all the way down to the food chopper and cleaned it out. I checked the float and the Float switch. All are fine. I checked the hose and also ok as I noted when the amount of water is small in the dishwasher it drains fine.

yep checked that also and it is fine.  what is weird it will drain if the water level is about 1 inch or so.  Above that it will not drain.
