Neville S Lacanada , CA January 15, 2018 The racks in my dishwasher were rusting through in several places and some of the upright dish holders were broken off I ordered new upper and lower racks. Installation for the bottom was literally just replacing the old rack. The upper rack required swapping out the upper spray rotor assembly and inserting the rollers into the slider. Still easily done. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
