Chances are you know your dryer has a vent and lint trap that needs cleaning regularly. But you might not realize there's a washing machine filter to catch and trap lint and other debris. This filter needs to be cleaned to ensure that your washer runs safely and at peak performance. Neglecting to clean a washing machine filter can leave clothes dirty and smelly and, over time, can cause damage to the machine itself.
Cleaning a washing machine filter requires locating it (this might be the trickiest part!), soaking and scrubbing it clean, replacing it, and running a short, empty wash cycle. This article provides all the information you need to clean the filter successfully, including how often it needs to be done.
13 Things You Should Never Put in the Washing Machine
Locating the Washing Machine Filter
To locate the filter on your washing machine, consult the owner's manual. Typically, the filter will be located in one of these places:
- In the center agitator
- In the drum's top lip
- Behind a trap door on the front exterior of the machine
- Near the water pump or at the end of the drainage hose
If you no longer have a physical copy of the owner's manual, it is likely available online and can be found by searching the make and model of your washer and the phrase "user manual." Visual learners might benefit from seeking out instructional videos, which can be found on YouTube. Many washing machine manufacturers offer instructional videos on their websites or social media channels.
It's also worth noting that many newer machines, including high-efficiency (HE) models, don't have a filter, instead relying on self-cleaning in the machine's pump mechanism. These types of filters generally do not require owner maintenance.

How Often to Clean a Washing Machine Filter
Manufacturer instructions regarding the frequency with which to clean a washing machine filter vary. It's best to consult the user manual for your particular machine, but general guidelines range from cleaning a washing machine filter once a month to cleaning the filter twice yearly.
Usage also plays a role in how often to clean a washing machine filter. Those in large households who use their washers more often than smaller households or who regularly launder heavily soiled items like outdoor work clothes or cloth diapers will want to clean the filter more frequently.
Signs that it's time to clean the filter include:
- Lint buildup or dirt deposits, including excess detergent, on clothes after washing
- Improper drainage that leaves clothes soaking wet at the end of the wash cycle
- A mildewy smell that indicates there is standing water in the washer's mechanisms
Some washers have disposable lint traps; when these types of filters become clogged, it is time to replace them.

How to Clean a Removable Washing Machine Filter
Most washing machine filters can be removed for cleaning. Here's how to do so.
Wipe Off the Filter
Remove the filter from its housing and gently wipe away lint and debris using a damp cleaning cloth.
Clean the Filter Housing
Use a cloth to wipe lint and debris from the filter housing. You might want to use a flashlight to examine the filter housing for buildup. Additionally, depending on the placement of the filter, you might want to put down a shallow basin or an old towel to catch any water that pours out when you open the filter housing.
How to Drain a Washing Machine
Soak the Filter
Fill a bucket, bowl, or basin large enough to submerge the filter with hot water and a small amount (about 1 tsp.) of dish soap or liquid laundry detergent. Allow the filter to soak in the solution for 10 minutes.
Scrub the Filter
Using a soft-bristle brush, such as an old toothbrush or a dish brush, scrub the filter to remove buildup.
Replace the Filter
Return it to the washer's filter housing, ensuring it is securely in place. Unlike dryer filters, washing machine filters don't need to be dry when replacing them, as they will get wet again.
Run a Short Wash Cycle
Run the washer's short cycle to check that the filter is securely in place. Remove the filter and reinsert it into its housing if you notice any leaks.

How to Clean a Fixed Washing Machine Filter
Some washing machine filters are secured in place, meaning you cannot remove them for cleaning. Here's how to clean a filter that is fixed in place.
Wipe the Filter and Housing
Open the filter housing and wipe away lint and debris using paper towels. Depending on the placement of the filter, you might want to put down a shallow basin or an old towel to catch any water that pours out when you open the filter housing.
Scrub the Filter
Using a soft-bristle brush, such as an old toothbrush or dish brush, scrub the filter to remove lint and debris that has built up on the washing machine filter.
Run a Short Wash Cycle
Run the washer's short cycle to flush out the freshly cleaned filter.
How to Clean a Pump Washing Machine Filter
Many newer HE washing machines don't have a filter or lint trap, instead using a self-cleaning pump to remove lint and other debris during the wash and cycle. While these pumps are technically self-cleaning, running a short, empty wash cycle to flush lint and buildup from the filter once every 1-3 months can help to keep the machine running properly.
