How to Clean a Dishwasher Filter Step-by-Step
Q: How do I clean a dishwasher filter step-by-step?
A: In most dishwashers, you can clean the filter by removing the lower rack, unlocking and lifting out the filter assembly, rinsing it with warm water, gently brushing off debris, and reinstalling it securely. A clean filter can improve washing performance, reduce odors, and help prevent standing water issues.
If your dishwasher is not cleaning well, smells bad, or leaves debris on dishes, filter maintenance is one of the first things to check. Related help: Dishwasher Not Cleaning, Why Is My Dishwasher Not Cleaning Dishes Well?, and Why Is My Dishwasher Smelling Bad?.
Why Dishwasher Filter Cleaning Matters
Your dishwasher filter catches food particles and debris so they do not recirculate back onto your dishes. When the filter gets clogged, you may notice poor cleaning results, bad smells, cloudy dishes, or water left in the bottom of the tub.
Routine filter cleaning can also support better detergent performance. If you are also troubleshooting residue or film, see our dishwasher detergent guide and white film on dishes guide.
Common Signs Your Dishwasher Filter Needs Cleaning
- Food particles left on dishes after a cycle
- Bad odor when opening the dishwasher
- Standing water in the bottom of the tub
- Longer wash times or poor rinse results
- Visible debris around the filter area
Safety First
- Turn off the dishwasher before cleaning.
- Let the interior cool if it just finished a hot cycle.
- Wear gloves if you are reaching around broken glass risk or sharp debris.
- Do not force parts if the filter assembly feels stuck.
What You Need
- Warm water
- Soft brush or old toothbrush
- Mild dish soap
- Soft cloth or sponge
How to Clean a Dishwasher Filter Step-by-Step
1) Remove the Bottom Rack
Slide out the lower dish rack to access the filter area at the bottom of the dishwasher tub.
2) Locate the Filter Assembly
Most dishwashers have a cylindrical filter and sometimes a flat mesh screen near the bottom spray arm. The exact shape varies by brand and model.
3) Unlock and Remove the Filter
Turn the filter counterclockwise (on many models) and lift it out. Some models use tabs or a locking cap. If it does not move easily, check your owner’s manual instead of forcing it.
4) Rinse Off Loose Debris
Rinse the filter under warm running water to remove food particles, grease, and residue.
5) Gently Brush the Filter
Use a soft brush and mild dish soap to clean the mesh and plastic frame. Avoid hard scrubbing tools that can damage the screen.
6) Clean the Filter Housing Area
Wipe the opening and surrounding sump area with a soft cloth to remove debris buildup. Be gentle and watch for sharp objects like broken glass.
7) Reinstall the Filter Securely
Place the filter back in position and lock it in place. Make sure it sits correctly and does not wobble. Running the dishwasher with a loose or missing filter can affect cleaning results.
8) Run a Test Cycle
Run a normal rinse or wash cycle and check whether cleaning performance improves. If you still have standing water, also review standing water in the bottom and why your dishwasher won’t drain.
How Often Should You Clean a Dishwasher Filter
A good starting point is every month for many homes. If you run the dishwasher daily, cook heavily, or rinse dishes lightly before loading, you may need to clean the filter more often.
Mistakes to Avoid
- Using wire brushes or abrasive scrub pads
- Forcing the filter assembly out
- Reinstalling the filter incorrectly
- Ignoring odors or standing water after cleaning
- Assuming detergent alone will solve a clogged filter issue

Frequently Asked Questions
Where is the dishwasher filter located?
On most dishwashers, the filter is located at the bottom of the tub under or near the lower spray arm, usually in the center or back corner area.
How often should I clean my dishwasher filter?
Many households do well with monthly cleaning, but homes that run frequent loads may need to clean the filter more often.
Can a dirty dishwasher filter cause bad smells?
Yes. Trapped food and residue in the filter can cause odors and may also reduce cleaning performance.
Can a clogged dishwasher filter cause standing water?
It can contribute to drainage and wash performance problems, especially when debris buildup is heavy. If standing water continues after cleaning, there may be a separate drain issue.
Do all dishwashers have a removable filter?
No. Many do, but the design varies by brand and model. Some filters are manual-clean style, while others differ in access or cleaning method.
What should I do if the filter will not come out?
Do not force it. Check the owner’s manual for the model-specific removal steps. Forcing the assembly can damage the filter or mounting area.
