How to Fix a Smelly Dishwasher
Why Dishwashers Smell
A smelly dishwasher usually means organic waste has accumulated somewhere inside the appliance.
Common sources include:
-
Food particles trapped in filters
-
Grease buildup
-
Mold growth
-
Detergent residue
Step 1: Clean the Dishwasher Filter
Most dishwashers have a removable filter at the bottom of the appliance.
Remove the filter and rinse it with warm water to remove trapped food particles.
Step 2: Run a Dishwasher Cleaning Cycle
Using a dishwasher cleaner tablet helps remove buildup from areas that cannot be reached manually.
A hot cleaning cycle helps dissolve grease, detergent residue, and bacteria.
Step 3: Clean Spray Arms
Spray arms can become clogged with food particles or mineral deposits.
Rinse them under hot water and clear any blocked holes.
Step 4: Clean the Drain
If the dishwasher drain contains grease or food sludge, odors may return quickly.
Running an enzyme cleaner through the appliance can help break down organic material inside the drain line.
Preventing Dishwasher Odors

-
Clean the appliance once per month
