    Default Dishwasher not draining water out completely

    Model Number: DU8150XB1
    Brand: Whirlpool

    We live in a rented home with the above mentioned Whirlpool dishwasher. The last few weeks, the dishwasher has water still in the compartment after a wash.

    I've tried using a plunger to plunge the drain hole at the bottom of the compartment, tried using baking-soda-vinegar-hot water trick to unblock anything down there.

    Last week, I pulled the drain hose from the air gap to see if water was flowing out, and it was flowing. It wasn't a forceful flow, though.

    I've been reading on the Internet that it could be the pump, impeller, or both.

    Any ideas as to cause and solution would be greatly appreciated.

    Thank you.

    when it tries to drain, do you hear the motor running/humming ?

    Did you check the drain hose from the air gap to where it goes to your garbage disposal or sink plumbing? I see a lot of clogs there as well.

    If thats fine, You'll need to check your funnel grate #19 here for clogs:

    Yes, I do. I even hear the water getting into the garbage disposal, but the sound of the water coming into the disposal isn't the same as before.

    Jake, Thank you for your advice. I'll check that grate when I get home this afternoon. How do I get that open? With a flathead screwdriver? And if there are no clogs under that grate....what's next?

    Yes, it should just unsnap with a flathead screwdriver.

    Then check that cone#18 and the ball#21, then the sump itself#17.

    Turn the breaker off to your dishwasher first.

    You may be able to do it all with the dishwasher in place.

    If not you'll need to pull it out.

    So, now....I've cleaned the sump, put it back all together, and now it still won't drain. I think I hear the drain sequence, but it trickles out.

    Do you know if this model uses the motor in reverse to drain the water out of the compartment? If that's the case, the motor does not reverse spin during the drain cycle.

    I'm going to take the dishwasher out again and remove the hose that's connected between the sump and the elbow that goes to the dishwasher drain hose. I'm hoping that it's blocked. If not.....I'm going to cry.

    It reverses on this model to drain.

    Yes, check for the blockage.

    If its not blocked don't cry, just be glad you can go new dishwasher shopping, they didn't make many of these models you have, and for good reason, you see why?

    Many members here have had the same issue with this model.

    This dishwasher is the one you'll want to buy next:
