My dishwasher fails to drain usually on the last drain cycle about once every 3 weeks, between those 3 weeks it operates fine. I have checked the tank, drainage pump, drainage hose and filters and all are clean and the hose has no kinks in it. One time that it failed to drain I happened to be close by and I could hear a sound of a motor but water was not draining into the sink.
ANSWER MJ, you'll need to remove the pump cover and lower spray arm and remove and check or replace the drain pump baffle 6-919119 . If or when the "flaps" of the baffle get deformed or bent they create a vortex and the tub will not drain.
