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

Safety first: Wear gloves if you are sensitive to cleaning chemicals or mold.

Step-by-step checks:

• Deep clean filters: Remove and scrub filters with hot soapy water. Clean the sump area thoroughly.
• Clean interior: Wipe the door edges, gasket, and corners with a cloth soaked in hot water and mild detergent or vinegar.
• Run cleaning cycle: Place a dishwasher cleaner or a cup of white vinegar on the top rack and run a hot cycle.
• Drying habit: Leave the door slightly ajar between cycles to allow moisture to escape.
• Check drain: Ensure there is no standing water left in the bottom after cycles; if there is, address drainage issues.

Warning: Do not mix bleach and vinegar; use one cleaning method at a time.
