How to remove odors in your dishwasher

How to remove odors from your dishwasher:

Is there a new plastic smell?

This is a normal smell and should dissipate with time (about 2 weeks). Try running a white vinegar rinse or using affresh® to help remove the odor. 

Run a white vinegar rinse to reduce odor:

  • Wash and rinse dishes. Do not use a heated dry option. Use an air-dry or an energy-saving dry option.  Remove all silverware or metal items.
  • Put 2 cups (500 mL) of white vinegar in a glass or dishwasher-safe measuring cup on the bottom rack.
  • Run the dishwasher through a complete washing cycle using an air-dry or an energy-saving dry option. Do not use detergent. The vinegar will mix with the wash water.
  • Run the dishwasher through a normal cycle with detergent after cleaning the interior.

Are dishes washed only every two or three days?

Run a "Rinse and Hold" or "Rinse Only" cycle once or twice a day until you have a full load.

Is there a petroleum smell?

This is a normal smell. Some models have sound-deadening material that smells like petroleum. This is normal and should dissipate in 4-6 weeks.

Is there a varnish smell?

This is a typical motor smell. Some motor windings are treated with a varnish. This smell will wear off in approximately one month.

Is there a burnt plastic smell?

Possible cause: Plastic parts that have fallen onto the heating element during a cycle.

  • Solution: Remove plastic parts from heater after it has cooled. After a few cycles, the excess plastic will burn off.

Possible cause: Washing plastics that are not dishwasher safe.

  • Solution: Wash only dishwasher safe plastics in the dishwasher.

Is there a musty, spoiled smell?

Standing water in the dishwasher can cause this smell. See information for "My dishwasher is not draining".
