Allen T Kalamazoo , MI November 24, 2018 Appliance: KitchenAid Dishwasher KUDR24SEBL2 Kitchenaid Dishwasher Kudr24sebl2: The upper spray arm broke off and one of the track stops broke. How to replace Track Stop. I replaced the parts. The video on the website was great. I'm glad I was able to find repair parts for such an old dishwasher. I'm squeezing as much life out of this unit as possible. Thanks. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
