Unpleasant odor coming from the dishwasher, especially when opening the door after it has been closed for a while.

Safety note: Use gloves when cleaning dirty components.

• Deep clean filters and sump: Remove filters and scrub with hot soapy water. Clean the sump area thoroughly.
• Clean door gasket: Wipe the door gasket and surrounding area with a mild bleach solution or dishwasher-safe cleaner.
• Run cleaning cycle: Run an empty hot cycle with a dishwasher cleaner or a cup of white vinegar on the top rack, followed by a baking soda rinse.
• Improve drainage: Ensure the drain hose has a proper high loop to prevent sink water from backflowing into the dishwasher.
