Strong musty or rotten odor coming from inside the dishwasher.

Safety First: Disconnect power if removing internal components.

Steps:

• Clean filters: Remove and scrub filters with hot soapy water.
• Clean sump: Wipe out the sump area and remove any trapped food or sludge.
• Run cleaning cycle: Run a hot cycle with a dishwasher cleaner or a cup of white vinegar placed on the top rack (no dishes).
• Improve drainage: Ensure the drain hose has a high loop and the sink/disposer drain is clear to prevent backflow.
• Leave door ajar: After cycles, leave the door slightly open to allow drying and reduce odor buildup.
