John K Oak Forest , IL December 27, 2015 The upper rack of dishes were not coming out clean in the dishwasher While cleaning and inspecting the interior of the dishwasher I found a crack in the plastic water supply pipi ( manifold ) that led to the upper sprayer. There also was a lot of debris where food and waste is ground up by the dishwasher. I clean that out put everything back together and the dishwasher works fine.
