John R. Weber J Scottsdale , AZ September 24, 2025 Appliance: KitchenAid Dishwasher, Built-In/Undercounter KDTE104ESS0 Kitchenaid Dishwasher Kdte104ess0: Broken / worn out seal. How to replace Water Supply Tube. Ordered a replacement part off another site that came in with an incorrect molded connection to the Spray Arm. The part broke my tabs on the Spray Arm and instead I bought both parts from this site. Both items were correct and resolved the issue. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
