Last week, Sarah noticed a bad smell coming from her dishwasher whenever she opened it, even after running it through a complete wash cycle. Most of us know what it's like to get that unpleasant surprise of a stinky dishwasher, and it usually means that bits of food and bacteria have collected in places we can't see.
According to Lauren Hill, cleaning expert at The Green Authority, "About 80% of dishwasher odors come from trapped food particles in the filter and spray arms, which most people forget to clean regularly."
Let's look at the best ways to get rid of those stubborn smells and stop them from coming back, so your dishes end up clean and fresh-smelling every time.
Stop Unpleasant Dishwasher Odors
While a smelly dishwasher can make your entire kitchen unpleasant, there are several effective ways to eliminate those unwanted odors.
We recommend starting with regular cleaning of the filter to prevent food buildup.
Next, run an empty cycle with vinegar to break down odor-causing residues, followed by a baking soda treatment.
Don't forget to leave the dishwasher door open between uses to prevent mold and mildew.

Things to Do When Cleaning a Smelly Dishwasher
A smelly dishwasher requires thorough cleaning to eliminate odors and guarantee proper sanitization.

- Empty dishwasher completely – Remove all dishes and racks to access all interior surfaces
- Clean filter system – Soak and scrub filter in warm soapy water to remove trapped food particles
- Vinegar cleaning cycle – Place 2 cups of white vinegar in bowl on bottom rack and run empty cycle
- Clean seals and edges – Wipe gaskets and door edges with soapy water, dry thoroughly
- Check drain hose – Inspect for blockages that could cause water backup and odors
- Run empty cycle – Complete final rinse cycle to guarantee all cleaning solutions are removed

Things to Avoid When Cleaning a Smelly Dishwasher
When dealing with a smelly dishwasher, proper cleaning techniques are essential to avoid causing further damage or worsening the odor problem.
Taking shortcuts or using incorrect cleaning methods can lead to mechanical issues, persistent smells, and potentially costly repairs that could have been prevented with proper maintenance and cleaning approaches.
- Harsh chemical cleaners or bleach – These can corrode internal components and damage the protective coating inside the dishwasher.
- Leaving the door closed after cleaning – Traps moisture and creates an environment where mold and bacteria can thrive.
- Overloading during cleaning cycles – Prevents proper water circulation and thorough cleaning of the interior surfaces.
- Skipping filter maintenance – Accumulated debris in filters will continue to cause odors even after cleaning other areas.
- Using excessive detergent – Can leave residue that attracts bacteria and creates unpleasant smells.
- Running cleaning cycles with dirty dishes – Food particles can redeposit throughout the dishwasher, defeating the purpose of cleaning.
- Ignoring spray arm maintenance – Blocked spray arms prevent proper distribution of cleaning solutions and water.

The process involves cleaning both the visible components and internal mechanisms to eliminate bacteria, mold, and food particles that cause unpleasant smells.
