Struggled with the pump running but only a trickle of water coming out of the drain hose. Didn't think that I had a drain back valve but after reading a few posts on here realized that the newer dishwashers have a flap in the drain hose at the pipe and rubber fitting end. Stuck a flexible pipe in and found a piece of plastic label caught in the flap area. Pulled it out and re ran the drain and it emptied completely. No idea how it would be possible to get past the screen and the filter, but fished it out and all is good now. Thanks for all the advise guys. Saved me a bunch of money on new parts and repairmen.
