Introduction
If your dishwasher has started leaving behind tiny food particles, cloudy residue, or unpleasant odors, the filter may be the hidden culprit. Learning how to clean a dishwasher filter can restore cleaning performance and extend the life of your appliance without spending money on repairs.
At Clean Home Craft, we’ve found that many homeowners don’t realize dishwasher filters require regular attention. A quick cleaning every few weeks can dramatically improve results. The good news is that this task takes less than fifteen minutes and requires only a few basic supplies.
Whether you’re tackling this chore for the first time or looking for better techniques, these practical steps will help you keep your dishwasher working efficiently.
Why You Should Learn How to Clean a Dishwasher Filter
Dishwasher filters trap food scraps, grease, and debris to prevent them from recirculating onto your dishes. Over time, buildup affects performance.
Common signs your filter needs cleaning include:
- Dishes coming out dirty.
- A bad smell inside the dishwasher.
- Water draining slowly.
- Visible food particles after a wash cycle.
- Reduced cleaning efficiency.
Regular maintenance prevents these issues before they become major problems.
Understanding Dishwasher Filters
Most modern dishwashers have removable filters located at the bottom of the tub.
Manual Filters
Manual filters require periodic cleaning by the user. They are quieter and more energy efficient.
Self-Cleaning Filters
These use grinders to break down food debris automatically. However, they may still benefit from occasional inspection and maintenance.
Check your owner’s manual to identify your dishwasher type.
Supplies Needed for How to Clean a Dishwasher Filter
You likely already have everything required:
- Warm water
- Dish soap
- Soft sponge
- Soft-bristled brush or old toothbrush
- Microfiber cloth

Step-by-Step Guide: How to Clean a Dishwasher Filter
Cleaning the filter is simpler than many people expect.
Step 1: Turn Off the Dishwasher
For safety, ensure the appliance is turned off and cool before beginning.
Step 2: Remove the Bottom Rack

Step 4: Unlock and Remove the Filter
Twist the cylindrical filter counterclockwise.
Lift it gently upward.
Carefully remove any secondary filter pieces.
Step 5: Rinse Under Warm Water
Run warm water over the filter to loosen food particles.
Avoid extremely hot water if the manual advises against it.
Step 6: Scrub Away Residue
Use a soft toothbrush with dish soap.
Focus on:
- Mesh sections.

- Hidden crevices.
Never force debris through the mesh.
Step 7: Clean the Filter Housing
Wipe the filter compartment with a damp cloth.
Remove visible debris from surrounding areas.
Step 8: Reinstall the Filter
Place all components back correctly.
Twist until securely locked.
An improperly installed filter can affect dishwasher performance.
