Strong bad odor from inside the dishwasher, especially when opening the door after idle periods.

Safety first: Wear gloves when cleaning internal parts.

• Clean filters thoroughly: Remove all filters and wash with hot water and detergent. Remove any trapped food.
• Clean sump and door seals: Wipe the sump area, door gasket, and corners with a mild disinfectant or dishwasher cleaner.
• Check drain hose routing: Ensure the hose has a high loop to prevent backflow from the sink.
• Run hot maintenance cycle: Run an empty cycle at the highest temperature with a dishwasher cleaner or a cup of dishwasher-safe descaler.
