Dishwasher failed to run normal cycle. Would fill and then empty, but would not run through the normal rinse/clean cycle. Determined that the Sump/Motor Assembly needed to be replaced. Dishwasher had to be pulled out to access part. Was difficult to snap into place and had to maneuver several times to get a tight seal before reattaching peripheral components. Ran a one-hour cycle to test for leaks and efficiency before reinstalling unit under counter.
