Whirlpool Dishwasher Smells Bad: Causes and Solutions

A Whirlpool dishwasher is designed to keep your kitchen clean and free of germs. However, an unexpected issue you might encounter is a foul odor coming from your appliance.

Understanding the Problem

A bad smell in your Whirlpool dishwasher can be caused by several factors. These may include:

  • Food residue: Leftover food particles might get trapped in the dishwasher’s nooks and crannies, leading to bacterial growth and unpleasant odors.
  • Drain hose or trap issues: A clogged drain hose or a full air gap can prevent water from draining properly, causing stagnant water and foul smells.
  • Dirty filter or strainer: Over time, the dishwasher’s filter or strainer can become clogged with food particles, leading to poor circulation and odors.
  • Mold or mildew growth: Moisture inside the dishwasher can foster mold or mildew growth, causing persistent bad smells.

Step-by-Step Fix Instructions

Let’s go through the troubleshooting steps to resolve a smelly Whirlpool dishwasher:

1. Clean the Filter and Strainer

  1. Access the filter: Most Whirlpool dishwashers have the filter located on the bottom front, near the door’s lower corner. Refer to your user manual if needed.
  2. Remove and clean: Take out the filter and rinse it under warm running water to remove any food debris. Use a soft brush if necessary.
  3. Replace the filter: Securely put the filter back in place.

2. Inspect and Clean the Drain Hose and Trap

  1. Locate the drain hose: The drain hose is usually found at the bottom of your dishwasher, connecting it to the garbage disposal or the sink’s drain.
  2. Check for clogs: Ensure that there are no blockages in the drain hose. If you find any, gently clear them with a thin wire or a pipe cleaner.
  3. Access and clean the air gap (if applicable): Some Whirlpool models have an air gap near your sink to prevent sewer gas from entering your dishwasher. Remove, clean, and reinstall it if necessary.

3. Run a Cleaning Cycle with Vinegar

Vinegar is an effective natural deodorizer for dishwashers:

  1. Add vinegar: Place a cup of white vinegar in the bottom of your dishwasher.
  2. Run a cleaning cycle: Select the hot water setting and start a cleaning or rinse cycle. The vinegar will help eliminate odors and dissolve any mineral deposits.

4. Check for Mold or Mildew

If you suspect mold or mildew growth:

  1. Clean with baking soda: Sprinkle a cup of baking soda on the dishwasher’s bottom and let it sit for 15-30 minutes. Then, run a hot water cycle to rinse.
  2. Check seals and gaskets: Inspect rubber door seals and gaskets for mold or mildew growth. Clean them with a mixture of equal parts water and vinegar using a toothbrush if necessary.

When to Call a Professional

If the above steps do not resolve your dishwasher’s bad smell, or if you notice any of the following signs, it might be time to call a professional:

  • Persistent foul odor after cleaning efforts.
  • Visible mold or mildew that does not respond to home remedies.
  • Water leaks or unusual noises from the dishwasher.
  • The smell is accompanied by poor performance, such as inefficient cleaning.

Prevention Tips

To keep your Whirlpool dishwasher fresh and odor-free:

  1. Scrape and rinse: Always scrape off excess food particles from dishes before loading the dishwasher and rinse lightly to prevent food residue buildup.
  2. Regular cleaning: Perform routine cleanings with vinegar or baking soda to maintain freshness.
  3. Check filters: Inspect and clean the filter regularly, as recommended in your user manual.
  4. Proper ventilation: Ensure adequate ventilation around your dishwasher to prevent moisture accumulation.
