Patricia M La Crescenta-Montrose , CA November 01, 2018 Appliance: KitchenAid Undercounter Dishwasher KUDS24SEWH2 Kitchenaid Dishwasher Kuds24sewh2: The 'innards' were rusted and corroded and the main sprayer didn't spin freely. How to replace Lower Dishrack. First, I watch the videos (GREAT feature)... then followed instructions. easy assembly, easy fix. My husband was impressed that I handled the repair (he doesn't consider me mechanical...) Dishwasher works like a charm with the new bearing- and upper dishrack assembly ( unknown to us the sprayer line on old rack had corroded through). Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
