Why Does My Dishwasher Smell?

Before exploring the solutions, understanding the root causes is important, so you can avoid this unpleasant odor in the future. Various factors contribute to the funky smell coming from your dishwasher.

Food Residue Buildup

One significant cause of a smelly dishwasher is the buildup of food particles. When plates are not adequately scraped or rinsed before being loaded into the dishwasher, these food remnants can accumulate in corners and tight spaces. Over time, this accumulation becomes the basis for unpleasant smells.

Standing Water

Another prevalent reason for a malodorous dishwasher is stagnant water. When water remains still in the dishwasher, it provides an ideal environment for bacteria and mold to thrive. The result is a foul smell that can permeate your dishes and kitchen. Regularly addressing these issues is essential to keeping your dishwasher smelling fresh and your kitchen free from unwanted odors.

Steps to Clean a Smelly Dishwasher

• Get Your Supplies Ready: Before you start cleaning, gather vinegar, baking soda, a soft brush, and a clean cloth.

• Clean the Filter Trap: Start by taking out and cleaning the dishwasher filter and trap. These parts often collect food bits, adding to the smell.

• Clean the Gasket Seals: The spray arms can clog with food particles over time. Look for any blockages in the spray arm holes, and try to remove those. If it is possible, you can detach the spray arm and run water through.

• Check the Spray Arms: The spray arms distribute water for cleaning. Over time, they can get clogged with food particles. Look for any blockages in the spray arm holes. Detach the spray arms if possible and run water through them to clear out any remaining particles.

• Use Vinegar or Baking Soda: Run a cycle with white vinegar by placing a cup of vinegar upright on the bottom rack. After the cycle is done, sprinkle one cup of baking soda at the bottom and run a hot water cycle.

• Run a Cleaning Cycle: If your dishwasher has a cleaning setting, use it to thoroughly clean and remove any leftover smell.

Keep Your Dishwasher from Smelling

• Scrape Dishes or Rinse Before Loading: Always take a moment to remove excess food from your dishes before placing them in the dishwasher. This simple step goes a long way towards preventing the buildup of food particles that can contribute to unpleasant odors. Scraping or rinsing ensures that the dishwasher operates efficiently and your dishes come out cleaner and fresher after each wash.

• Monthly Dishwasher Cleaning: In addition to regular usage, it's crucial to implement a monthly maintenance routine for your dishwasher. This proactive approach keeps your appliance in optimal condition, preventing the accumulation of residue and potential odors. Set a specific day each month to clean the various components of your dishwasher, such as the filter, trap, and spray arms.

• Keep Your Dishwasher Door Open: Allowing the dishwasher to air out between cycles promotes better ventilation, hindering the growth of mold and bacteria. This simple habit contributes to a fresher-smelling dishwasher and ensures that when you do run a cycle, it starts with a clean and odor-free interior.

Natural Ways to Remove Odor from Dishwasher

• Citrus Peels: Place lemon or orange peels in the utensil rack to help eliminate odors with their natural oils.

• Use Essential Oils: Put a few drops of essential oils on a cotton ball inside the dishwasher for a pleasant scent.

• Baking Soda and Vinegar: Mix baking soda and vinegar periodically to keep your dishwasher fresh.
