Dishwasher smells bad

A foul-smelling dishwasher can quickly turn your kitchen into an unpleasant environment. The good news is that dishwasher odors are a common issue and can usually be resolved with some simple maintenance and cleaning. In this guide, we’ll explore the common causes of a smelly dishwasher and provide effective solutions to help you get rid of those unpleasant odors.

Common Causes of a Smelly Dishwasher

  1. Food Residue: Food particles left on dishes can accumulate in the dishwasher’s interior, filters, and spray arms, leading to unpleasant odors.
  2. Standing Water: Water that remains trapped in the bottom of the dishwasher, especially in hidden areas, can become stagnant and produce a musty smell.
  3. Clogged Filters: Over time, filters in the dishwasher can become clogged with debris, making it difficult for the appliance to remove food particles and excess moisture.
  4. Mold and Mildew Growth: The warm and moist environment inside the dishwasher is conducive to mold and mildew growth, which can cause foul odors.
  5. Blocked Drain Hose: A blocked or partially blocked drain hose can lead to improper drainage, causing water to accumulate and develop unpleasant smells.

Solutions for a Fresh-Smelling Dishwasher

  1. Clean Food Residue:
    • Before loading dishes, scrape off excess food to prevent it from accumulating in the dishwasher.
    • Regularly remove any food particles from the dishwasher’s interior, including the filter, spray arms, and door gasket.
  2. Run Hot Water Before Starting:
    • Run the kitchen faucet until the water is hot before starting the dishwasher to ensure that hot water is used throughout the cycle, which can help eliminate odors.
  3. Clean and Maintain Filters:
    • Remove and clean the dishwasher’s filters per the manufacturer’s instructions. Clean filters ensure proper water circulation and drainage.
  4. Use Vinegar or Baking Soda:
    • Place a cup of white vinegar or baking soda on the top rack of the empty dishwasher and run a hot water cycle to help remove odors and residue.
  5. Check for Mold and Mildew:
    • Inspect the interior of the dishwasher, especially around the door gasket and hidden corners, for mold and mildew. Clean with a mixture of water and vinegar or a mild bleach solution.
  6. Empty the Drain:
    • Check the dishwasher’s drain area for any debris or standing water. Remove any blockages and ensure proper drainage.
  7. Regular Maintenance:
    • Routinely clean the interior of the dishwasher, including the walls, door, and racks.
    • Wipe down the door gasket and seals to prevent mold growth.
    • Clean the exterior of the dishwasher to prevent odors from lingering on the surface.
  8. Consider a Commercial Dishwasher Cleaner:
    • Some dishwasher manufacturers offer specialized cleaning products designed to eliminate odors and remove buildup.
  9. Leave the Door Ajar:
    • After a wash cycle, leave the dishwasher door slightly open to allow for air circulation and prevent moisture buildup.


A smelly dishwasher repair can be an unpleasant issue, but with regular maintenance and proper cleaning, you can ensure that your dishwasher not only cleans your dishes effectively but also maintains a fresh and odor-free environment.
