    Default Maytag QuestSeries 300 - not draining completely

    Just as the title states. It does not drain completely & over time hods quite a bit of water. I am sure the pump is good very solid stream, pressure seems is fine. hen I initiate the test sequence the pump runs for the full 2 min. After pulling the pump I think the flapper is not sealing water out when the pump stop. The flapper is not torn or have a hole. However it does not seat completely, it will seat if it is pushed down.

    Any thoughts?

    Thanks,
    Mike

    I should have posted that in the original post, MDBH970AWS. The pump has a polly/rubber flapper on the inlet & the outlet. The inlet flappers look fine the outlet is not "damaged" but it does not close all the way either, even when you rotate it vertically so gravity could pull it closed Just guessing it is 1/8" or more. Just guessing as the pump seems strong, pressure wise considering it is not a really tight tolerance due to the requirement it carry out any bits of food.

    Thanks Mike,

    I found another member with the same issue you have here:
    http://www.applianceblog.com/mainfor...ad.php?t=12352

    Seems they have upgraded the drain pump, and a new drain pump should fix yours as well.

    Its the exact same drain pump as yours, you can order it here:
    Drain Pump Assembly - Manufacturer part number 99002750 is RepairClinic item number 1012056

    I found that post too. Guess I am having a hard time believing it is the pump. I am stuburn, at least that is hat the wife tells me... At this point a $43 pump is looking good. I am tired of thinking about this darn thing. :-)

    Many thanks for you help. Great site!!!

    Will do. Parts are ordered. FWIW, that pump pictured looks exactly like mine, with the dark read "flapper".

    I received my parts today & installed them. All except for the the door latch handle, darned if it is not the correct one... Oh well my fault, $5 lesson. :-) Will need to order the complete latch assembly.

    After getting the new pump installed I do not think there was anything wrong with the old one, guess I have a spare now! :-) Why do I think the old one was OK??? GLad you asked! I guess I was paying closer attention when testing the new pump Keep in mind I have not run a complete cycle but I canceled the wash & initiated the 2 min drain cycle. I noticed just before the drain cycle stopped that there was water being pumped back into the tub, opened the door & sure enough it was gushing back in!!! I did the same test again & opened the door before the drain cycle was over, dry as a bone with NO water re-entering from the drain hose. So I closed the door & let the drain cycle finish. Opened the door & sure enough there was water in the bottom!

    After the drain cycle is there supposed to be water pumped into the dishwasher??? I would think not at this would be asking for mod to grow... I must assume that the control board is going bad?.?.?.

    Looks like they list 3 different circuit boards for my model, MDBH970AWS, not sure what to order,:
