Strong, unpleasant odor coming from inside the dishwasher, especially when the door is opened.

Safety first: Turn off the power before reaching into the sump.

• Clean filters thoroughly: Remove and scrub the filters with hot, soapy water.
• Clean sump and door seals: Wipe the sump area, door gasket, and the area around the bottom of the door with a mild cleaner.
• Run hot cleaning cycle: Use a Bosch dishwasher cleaner or a dishwasher-safe descaler and run the hottest cycle with an empty dishwasher.
• Use regular hot cycles: Periodically run intensive/hot programs to reduce residue buildup.
• Check drain connection: Ensure the drain hose is not sagging and trapping dirty water.
