Step-by-step troubleshooting
Clean the Filter
Do: Locate and remove the filter at the bottom of the dishwasher. Rinse it under running water and use a soft brush to remove debris.
Observe: Filter is clean and free of food particles.
Means: Filter was clogged and causing odor.
Next: Run a cleaning cycle with vinegar or dishwasher cleaner.
Check the Drain
Do: Inspect the drain at the bottom of the dishwasher for clogs. Use a plunger or a small brush to clear any blockages.
Observe: Drain is clear and water flows freely.
Means: Clogged drain was causing standing water and odor.
Next: Run a cleaning cycle with vinegar or dishwasher cleaner.
Clean the Interior
Do: Mix a solution of white vinegar and water. Wipe down the interior walls, door, and seals with a soft cloth or sponge.
Observe: Interior is clean and free of visible mold or grime.
Means: Mold or buildup was causing the odor.
Next: Run a cleaning cycle with vinegar or dishwasher cleaner.
Run a Cleaning Cycle
Do: Place a dishwasher cleaner or a cup of white vinegar in a dishwasher-safe container on the top rack. Run a hot water cycle without dishes.
Observe: Dishwasher runs a full cycle and emits a clean smell.
Means: Buildup and odors were successfully removed.
Next: Check if the smell is gone after the next load of dishes.
Inspect the Drain Hose
Do: Check the drain hose for kinks, clogs, or mold. Clean or replace if necessary.
Observe: Drain hose is clear and free of mold.
Means: Clogged or moldy drain hose was causing odor.
Next: Run a cleaning cycle with vinegar or dishwasher cleaner.
Check the Door Seal
Do: Inspect the door seal for mold or debris. Clean with a damp cloth and mild detergent.
Observe: Door seal is clean and dry.
Means: Mold on the door seal was causing the odor.
Next: Run a cleaning cycle with vinegar or dishwasher cleaner.
