Thomas S Temple , NH May 08, 2015 Appliance: KitchenAid Dishwasher - Undercounter KUDH230B0 Kitchenaid Dishwasher Kudh230b0: Water leaking out the bottom door when appliance running. How to replace Door Gasket. Replaced seal around tub which matches up to the door. Note: Once you receive the replacement seal/gasket you will be able to see how the gasket is attached to the tub. I used a firm flat blade scraping putty knife to depress the clips....once you receive the gasket you'll understand what I'm referring to. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
