Peter M Novi , MI October 16, 2015 Appliance: KitchenAid Undercounter Dishwasher KUDE70FXSS3 Kitchenaid Dishwasher Kude70fxss3: The arm spray had come off the spinner and fallen into washer basin and was melted by the heating elements. How to replace Arm-Spray. The arm spry snaps back into place. It's designed to only fit one way so you can't put it in upsided down. It twists into place and then locks in with tabs. It takes a little tricky, but look carefully at the parts. Everything snaps into place perfectly. Since the rack pulls out you don't even have to work inside the dishwasher. No tools needed. 10 minute fix. Save yourself a $150 repair visit. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
