Dishwasher emits a bad smell, musty or rotten odor when opened.

Safety first: Unplug the dishwasher before deep cleaning internal parts.

• Thoroughly clean filters: Remove and scrub the filter assembly with hot soapy water. Clean the coarse filter and fine mesh.
• Clean sump and door seals: Wipe the sump area, door gasket, and corners of the tub with a cloth soaked in hot water and mild detergent.
• Run a hot cleaning cycle: Use a dishwasher cleaner or a cup of white vinegar on the top rack and run the hottest program with no dishes.
• Use regular hot cycles: Avoid using only low-temperature eco cycles. Run an intensive program periodically to reduce grease build-up.
• Check drain hose: If odor persists, the drain hose or sink trap may harbor debris. Clean or replace as needed.
