Samai S Goldsboro , NC May 07, 2022 Appliance: Kenmore Dishwasher 66514562N611 Kenmore Dishwasher 66514562N611: Dishwasher not cleaning good also leaking. How to replace Cover. Hands down the best place to buy parts. All I did was remove the spray arm that the water goes through. Then I remove the cap that is connected to the diffuser. It took about 5-10 minutes to replace part. Now my dishwasher working perfectly. No more leaks because of the spray arm. And now their is enough pressure for the water to spread evenly and clean throughout dishwasher. Happy now I do not have to wash all the dishes throughout the day.
