Hotpoint Aquarius FDM 550 Dishwasher Only Cleans the Bottom Rack
If a Hotpoint Aquarius FDM 550 cleans the bottom rack but leaves the upper rack dirty, start with the upper-rack wash path rather than assuming the filter or detergent is the whole problem. Confirm the full model suffix on the rating plate, then isolate power and check that the upper spray arm is clear, turns freely by hand, and is not blocked by a tall item or a rack/feed connection that shifted during the move.
