George P Tualatin , OR February 01, 2020 Appliance: Kenmore Dishwasher 66515979990 Kenmore Dishwasher 66515979990: Leaking below the door. How to replace Lower Door Seal Kit. Replaced door Gasket and Lower Door seal. It was a challenge to get the door off. Also trying to replace those little cups on both sides of the dishwasher was a real challenge. Had a heck of a time removing just one and replacing. I opted to put the original back because they where fine. The dishwasher is still leaking near the lower right hand side. Not much leaking like before, so I'm not quite sure what is going on. Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
