After dish washer completes cycle there is residual water left in the bottom of the dishwasher.What is wrong?
Answer Al, You'll need to disconnect the drain hose from the plumbing under the sink, check for any clogs or kinks in the hose. Start the dishwasher. allow it to fill and wash a few seconds, then drain the dishwasher, into a large bucket, this should flush any debris in the hose. Remove the sump cover and filter in the tub, and check and remove any debris in the sump. Then remove the piston and nut assembly WD24X10018 and check that it is opening and closing properly, and not stuck open due to debris.
