If the dishes in your dishwasher come out clean, then the dishwasher itself must be clean, right? Unfortunately, when your dishwasher smells bad you’ll learn this is not the case.

It’s recommended that you clean home appliances like a dishwasher every 1-3 months to avoid mold buildup. But what is the best way to clean the inside of a dishwasher?

What to do When Your Dishwasher Smells Bad

Want to know where to start when your dishwasher smells bad? We’ve broken down how to clean a dishwasher into easy-to-follow steps that can be part of your regular dishwasher maintenance.

How to Clean Inside a Dishwasher

If your dishwasher smells like mold, it could be a sign that the inside needs cleaning. Mold and bacteria love to hide in the small parts and crevices inside the dishwasher. Here’s how to banish them for good:

  1. Remove the dishwasher’s bottom rack and wipe away visible debris.
  2. Inspect the spray arms for blockages and scrub them with a toothbrush dipped in white vinegar. Replace the bottom rack.
  3. Set a small dishwasher-safe bowl of white vinegar in the top rack and run a normal clean cycle with hot water.
  4. When the first clean cycle is complete, sprinkle a handful of baking soda in the bottom of the dishwasher. Run a quick wash cycle with hot water.
  5. Bonus Step: If moldy buildup is a lingering problem, run a third clean cycle after adding a cup of bleach to the bottom of the dishwasher. Do not try this step if your dishwasher has a stainless steel interior.

  2. Twist the filter to remove it. If there is a lower filter underneath, remove that as well.
  3. Using warm, soapy water, hand wash the filters. Scrub lingering particles gently with a toothbrush or sponge.
  4. Wipe away any debris around the filter’s location with a paper towel
  5. Reinstall the filter, twisting to lock it in place.

How to Clean a Clogged Dishwasher

Sometimes a clogged dishwasher drain is the cause when your dishwasher smells bad. Large food particles or a buildup of grime on your filter are ways your drain could become clogged. Follow these steps for how to clean a clogged dishwasher:

  1. Disconnect the dishwasher.
  2. Remove the dishwasher’s filter and unscrew the drain catch from the bottom of the dishwasher (consult your owner’s manual for details if necessary). You should be able to see down into the drain.
  3. With a straightened wire hanger, remove any visible clogs.
  4. Flush the drain with 1 Tbsp of baking soda and 2 Tbsp of white vinegar. Allow it to sit for 10-15 minutes.
