Tristan G Gig Harbor , WA April 06, 2021 Not cleaning effectively, particularly upper rack Super simple fix after identifying the missing/broken parts which included the top spinner and the rear nut for the center spinner that is supposed to have a rubber gasket to make a good seal when the top rack is slid into place. No tools required and now cleans like a new dishwasher again! Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
