Dishwasher has a bad odor; smells musty or like rotten food even when empty.

Safety first: Wear gloves when cleaning internal parts with chemicals.

• 1. Deep clean filters: Remove all filters and soak them in hot soapy water. Scrub away grease and trapped food.
• 2. Clean sump and spray arms: Wipe the sump area with a cloth and mild cleaner. Remove and clean spray arms thoroughly.
• 3. Door seal and edges: Wipe the door gasket and the area around the door edges where food particles can accumulate.
• 4. Run cleaning cycle: Run an empty hot program with a dishwasher cleaner or a cup of white vinegar placed upright on the top rack (no dishes).
• 5. Use hotter cycles: Periodically run an intensive program to reduce biofilm buildup.
• 6. Check drain hose routing: Ensure the hose has a high loop to prevent dirty sink water from backflowing into the dishwasher.
