Everett S Visalia , CA March 03, 2023 Appliance: Whirlpool Undercounter Dishwasher DU811SWPU2 Water not completely emptying out of the tub. Noted damaged gasket seal and support during water removal. Cleaned all pumps, filter, and screens. Changed air gap device. Replaced parts that were ordered. Used 1 cup of vinegar and baking soda to clean rest of dishwasher drainage system.
