If your dishes are coming out of the dishwasher still dirty, cloudy, or covered in tiny food particles, the problem might not be your dishwasher—it could be a dirty dishwasher filter.
Many modern dishwashers have a removable filter that traps food debris during the wash cycle. Over time, this filter can become clogged with grease, food particles, and soap residue, which prevents your dishwasher from cleaning properly.
Learning how to clean your dishwasher filter is one of the easiest ways to improve dishwasher performance and keep your dishes sparkling clean.
What Does a Dishwasher Filter Do?
The dishwasher filter collects:
- Food particles
- Grease residue
- Soap buildup
Without a filter, these particles would recirculate through the dishwasher and stick back onto your dishes.
However, when the filter becomes clogged, it can cause:
- Dirty dishes after washing
- Bad dishwasher odors
- Water draining slowly
- Food particles left on plates and glasses
Cleaning your filter regularly helps your dishwasher work more efficiently.
How Often Should You Clean Your Dishwasher Filter?
Most experts recommend cleaning the dishwasher filter once a month.
You may need to clean it more often if:
- You run the dishwasher daily
- You don’t scrape food off dishes first
- You notice odors coming from the dishwasher
Regular cleaning prevents buildup and keeps your dishwasher running smoothly.
Where Is the Dishwasher Filter Located?
In most dishwashers, the filter is located at the bottom of the dishwasher tub, underneath the lower spray arm.
To find it:
- Open the dishwasher door
- Remove the bottom rack
- Look for a round or cylindrical filter near the base
Most filters twist out easily for cleaning.
How to Clean a Dishwasher Filter
Cleaning a dishwasher filter only takes a few minutes and requires minimal supplies.
Step 1: Remove the Bottom Rack
Slide out the bottom rack of the dishwasher to access the filter area.
Step 2: Twist and Remove the Filter
Most dishwasher filters twist counterclockwise to unlock.
Carefully lift the filter out of the dishwasher.
Step 3: Rinse the Filter Under Warm Water
Rinse the filter under warm running water to remove food particles and debris.
If grease buildup is present, use a soft brush or old toothbrush to gently scrub the filter.
Step 4: Use Dish Soap for Grease Buildup
If the filter is greasy or sticky, wash it with warm water and a small amount of dish soap.
Avoid using abrasive scrubbers that could damage the filter mesh.
Step 5: Reinstall the Filter
Once the filter is clean:
- Place it back into the dishwasher
- Twist it clockwise to lock it into place
Make sure the filter is fully secured before running the dishwasher again.
Signs Your Dishwasher Filter Needs Cleaning
A clogged dishwasher filter often causes noticeable problems.
Watch for these signs:
- Food particles on dishes after washing
- Dishwasher smells bad
- Water draining slowly
- Cloudy glasses or plates
If you notice any of these issues, cleaning the filter may solve the problem immediately.
Bonus Tip: Clean the Dishwasher While You’re at It
While cleaning the filter, it’s also a good time to clean the inside of your dishwasher.
To do a quick dishwasher cleaning cycle:
- Place a bowl of white vinegar on the top rack
- Run a hot wash cycle
This helps remove grease, odors, and mineral buildup.
Why Cleaning Your Dishwasher Filter Matters
A clean dishwasher filter helps your appliance run more efficiently and prevents food particles from being redeposited on dishes.
By simply cleaning the filter once a month, you can:
- Improve dishwasher cleaning performance
- Prevent unpleasant odors
- Extend the life of your dishwasher
- Keep dishes sparkling clean
If you’re still having trouble with dirty dishes, you may also want to review how to load a dishwasher the right way, since proper loading allows water to circulate and clean dishes effectively.
With just a few minutes of maintenance, your dishwasher can keep working like new.
