Kithchen aid (Whirlpool?) dishwasher not draining but cycles through complete wash. I took apart the bottom filters and exposed the litle grinder with the screen. I poked around and damaged the flapper. I had another kitchenaide dishwasher and took the flapper out of it and noticed that the flapper seemed a little bit thinner compared to the flapper I damaged. Put back together and worked okay untill Wife noticed water in bottom of dishwasher. So I cleaned out the bottom screens again and ran the dishwasher witheverything taken off on the bottom like all of the screens and stuff. then I did a drain cancel and it started to drain again Now not draining right again did same thing and starts to drain again Do I have wrong Flapperor perhaps in the pump motor wearing out and is not strong enough to pull flapper open to drain. Is there more than on flapper for these older kitchen aid Dishwashers
