Maytag jet clean quiet 200 found no water pressure upper Rack.Traced problem to there is nothing to stop upper rack from getting pushed against door when pump starts It pushes top rack out of rear docking station. I cant see whats missing from the front of upper rack that is supposed to keep it tight against rear wall. Also noticed a oval hole to the side of docking station that is open and just blows water sideways against rear wall. I cant find anything missing from the upper rack or from this oval hole in any parts diagrams ???
