How Often Should You Clean Your Washer Filter?
Washer filters play a critical role in preventing clogs, improving drainage, and keeping your machine running efficiently. Yet most homeowners don’t realize their washer even has a filter, let alone how often it needs cleaning.
The truth is simple:
Most washer filters should be cleaned every 1–3 months, depending on usage, washer type, and the kinds of loads you wash.
This guide breaks down everything you need to know — including how often to clean your filter, how to tell when it’s clogged, and how to clean it safely.
Why Washer Filters Need Regular Cleaning
Washer filters trap:
- Lint
- Hair
- Coins
- Buttons
- Fabric threads
- Detergent residue
- Pet fur
- Small objects left in pockets
Over time, these materials build up and cause:
- Slow or poor drainage
- Washer not spinning properly
- Error codes
- Musty odors
- Standing water in the drum
- Increased wear on the drain pump
A clean filter keeps your washer running efficiently and prevents expensive repairs.
How Often Should You Clean Your Washer Filter?
The ideal cleaning frequency depends on your washer type and usage.
Front-Load Washers
Front-load washers have a dedicated drain pump filter (usually behind a bottom access panel).
Recommended cleaning interval:
Every 1–2 months
Clean it more often if:
- You wash pet bedding
- You wash heavily soiled clothes
- You do large family loads
- You notice slow drainage
Top-Load Washers
Top-load washers vary:
- Some have lint filters inside the agitator
- Some have mesh filters on the drum walls
- Some rely on self-cleaning pump filters
Recommended cleaning interval:
Every 2–3 months (if your model has a removable filter)
If your top-load washer uses a self-cleaning pump, run a tub clean cycle monthly.
High-Usage Households
If you do 5+ loads per week, clean your filter:
Every 4–6 weeks
Low-Usage Households
If you do 1–2 loads per week, clean your filter:
Every 2–3 months
Signs Your Washer Filter Needs Cleaning
You should clean the filter immediately if you notice:
- Water draining slowly
- Washer not spinning out clothes fully
- Error codes related to drainage
- A musty or sour smell
- Standing water in the drum
- Loud humming from the drain pump
- Visible lint or debris in the door gasket (front-load)
If your washer displays a drainage-related error code, check your brand’s error code hub:
How to Clean a Front-Load Washer Filter
Most front-load washers have a filter behind a small access door at the bottom front of the machine.
1. Turn off the washer
Unplug it for safety.
2. Place a towel and shallow pan under the filter
Water will drain out.
3. Open the access panel
Some require a flat screwdriver.
4. Pull out the drain hose (if present)
Drain the water into the pan.
5. Unscrew the filter counterclockwise
Remove lint, coins, hair, and debris.
6. Rinse the filter under warm water
Use a soft brush if needed.
7. Clean the filter housing
Remove any trapped debris inside the cavity.
8. Reinstall the filter and close the panel
How to Clean a Top-Load Washer Filter
Top-load filters vary by design.
Agitator Filter (Inside the Agitator)
- Remove the agitator cap
- Pull out the lint cup
- Rinse and reinstall
Drum Wall Filter
- Look for mesh screens along the drum
- Remove and rinse
Self-Cleaning Pump Filter
These cannot be removed.
Run a tub clean cycle monthly using:
- Hot water
- Washer cleaner
- Vinegar (if allowed by your manufacturer)
What Happens If You Don’t Clean the Filter?
Ignoring your washer filter leads to:
- Drain pump strain
- Clogged hoses
- Standing water
- Mold and mildew
- Error codes
- Longer wash cycles
- Poor cleaning performance
- Premature pump failure
A clogged filter is one of the top causes of washer drainage issues.
How to Find Your Washer Filter
Filter locations vary by brand:
Front-Load
- Bottom front panel
- Behind a small square door
Top-Load
- Inside agitator
- Under agitator cap
- Along drum walls
- Behind the rear panel
- No removable filter (self-cleaning models)
If you’re unsure, check your brand’s maintenance guide or error code hub.
