When to Clean Washing Machine Filter: A Practical Guide for Homes
Discover exactly when to clean your washing machine filter, the signs it needs attention, and a practical maintenance plan to boost efficiency and longevity.
By the end of this guide, you’ll know exactly when to clean your washing machine filter, how often to check it, and the steps to do it safely. You’ll recognize common warning signs such as slow draining or unusual odors, understand why filters clog, and adopt a simple, repeatable maintenance routine to keep laundry day running smoothly.
What the washing machine filter does and why it clogs
Your washing machine filter is a small screen that captures lint, hair, detergent scum, and other debris before water moves on to the drain. By catching particles, the filter protects the pump and helps maintain efficient drainage. Over time, fibers from towels, pet hair, and mineral buildup can accumulate on the filter, narrowing the opening and forcing the pump to work harder. According to Best Washing Machine, keeping this filter clean is one of the simplest ways to maintain drainage efficiency and prevent unexpected downtime. The Best Washing Machine team found that a well-maintained filter often correlates with fewer clogs and cleaner drains, especially in homes with hard water or high laundry turnover. Understanding how your filter works helps you spot problems early and plan regular maintenance rather than rushing to a repair service. Note that some washer models use a removable pump filter, while others rely on a fixed screen behind the access panel. Always check your manual to locate yours.
Signs your filter needs cleaning
Look for slower-than-usual draining, water pooling in the drum, or clothes coming out still damp. Odors during or after a wash can indicate mold or mildew on the filter or housing. You may also see visible debris on the filter itself when you open the access panel. If you hear the pump working louder or longer than normal, or you notice more lint on clothing, these are indicators that debris has built up. If you notice the washer won’t drain or leaves water in the drum, a clogged filter is a likely culprit. In such cases, plan a cleaning session before performing additional cycles. Regular observation is key; even without obvious signs, a routine clean helps prevent surprises.
How often to inspect and clean based on usage
There isn’t a universal schedule that fits every home. If you run several loads daily, have multiple pets, or wash large quantities of towels or denim, you’ll want to inspect more frequently. Homes with hard water or high mineral content may see faster buildup, while households with soft water might enjoy longer intervals between cleanings. The cadence also depends on your washer type; front-load and high-efficiency machines can accumulate debris more quietly than older models. Regardless of your setup, listening for slower drainage and checking the filter during routine cleanouts keeps you ahead of problems. A practical approach is to combine visual checks with a feel-test for any resistance when water flows to the drain.
Different filter types and where to find them
Washing machines use at least two common filtration mechanisms: a lint screen and a drain-pump filter. The lint screen is usually located inside the agitator area or along the drum rim in top-load models, and behind a small access door in some front-loads. The drain-pump filter protects the pump housing and is often inside a small hatch on the lower front panel. Some washers label the filter as 'filter', 'lint screen', or 'pump screen'. Refer to your user manual for exact location and any model-specific steps. If you can’t locate a filter, your machine may use a fixed filter or rely on a filterless design where lint is managed elsewhere. In either case, periodic cleaning or flushing is recommended to maintain flow.
What affects cleaning frequency (hard water, pets, laundry load)
Hard water speeds mineral buildup and residue formation, accelerating filter clogging. Pet hair and long-haired fabrics shed more fibers that trap in the filter. Large families generate more laundry, which increases debris and grime in the filter. The type of detergents and their residues can also influence how quickly a filter clogs; some formulas leave soap scum that binds with hair and lint. Additionally, if you frequently wash bulky items like blankets or towels, you’ll likely need to inspect and clean more often. By understanding these factors, you can tailor your maintenance cadence to your household, not just a calendar.
How to prepare for cleaning (safety and setting up)
Before you begin, unplug the washer to avoid any electrical risk. If your model is front-loading or has a pedestal, move it slightly away from walls to access the lower front panel. Have a basin or tray ready to collect dirty water and a towel for spills. Gather gloves, a soft brush, and a small cloth for wiping. If you use a cleaning solution, choose a mild detergent or a simple rinse; avoid strong chemicals that can damage seals. Check the drain hose for kinks and clear any kinks before you start; a blocked hose can complicate drainage after you remove the filter. Finally, review the owner’s manual for any model-specific cautions.
A safe, non-damaging cleaning method
- Remove power and access the filter. 2) Retrieve the filter and inspect for visible debris. 3) Rinse the filter under running water, using a brush to loosen stubborn buildup. 4) Wipe the housing with a damp cloth. 5) Reinstall the filter securely and close the access panel. 6) Run an empty wash cycle with hot water to flush the system. 7) If odors persist, repeat with a mild cleaning solution and rinse thoroughly. This approach minimizes risk to seals and avoids harsh chemicals.
Post-cleaning checks and best practices
After reassembling, run a short cycle to confirm proper drainage and absence of leaks. Check the door seals and panel for dampness. Keep a microfiber cloth handy to wipe any residual moisture around the filter housing. Note any changes in washing performance and odor. Document your maintenance date if you’re tracking care in a notebook or app; consistency matters. If you notice recurring problems, consider professional service to inspect seals and hoses beyond the filter. Regular reminders or calendar prompts can help you maintain the habit.
Common mistakes to avoid and maintenance cadence
Avoid pulling on hoses or forcing a stubborn filter; damage to seals and panels can occur. Don’t skip unplugging the unit or ignore standing water near electrical components. Avoid using aggressive chemicals that can corrode gaskets. Do not neglect to dry the interior after cleaning to prevent mold. Finally, don’t rely solely on a calendar; use the signs and the usage pattern to guide frequency. Adopting a simple cadence—check during or after heavy-load days—reduces risk of clogs and odors.
Quick troubleshooting if issues arise after cleaning
If water continues to back up or the washer won’t drain after filter cleaning, first re-check the filter installation for a proper seal. Inspect the drain hose for blockages or kinks and clear them if needed. If the problem persists, run a diagnostic cycle or consult the model’s troubleshooting guide. Some models require a reset or a service code to clear a drain error after maintenance. In cases of persistent leaks, hoses or seals may be compromised and warrant professional service.

Steps
Estimated time: 30-45 minutes
- 1
Unplug the washer and prepare space
For safety, unplug the washer and turn off the water supply if applicable. Move the unit slightly to access the filter area and lay a towel and basin within reach. This reduces the risk of electric shock and keeps spills contained.
Tip: Keep the manual nearby in case your model has a unique access method. - 2
Locate the filter access
Identify whether your model uses a lint screen or a drain-pump filter. Front-loaders often have a lower-front panel, while top-loaders may have an interior lint screen near the agitator. Some panels conceal the filter behind a small door.
Tip: Refer to your manual to avoid forcing panels or breaking clips. - 3
Remove the filter cover
Gently loosen and remove the filter cover or access cap. Some models require a quarter-turn; others use a catch. Hold the cover so it doesn’t drop into the sump.
Tip: Have a tray ready for loose debris that pops out during removal. - 4
Extract and inspect the filter
Carefully pull out the filter screen and examine for hair, lint, and mineral buildup. If the filter is stiff or lodged, don’t yank; wiggle gently to release.
Tip: Note orientation for proper reinstallation. - 5
Rinse and scrub the filter
Rinse the filter under running water, using a soft brush to loosen stubborn residues. Avoid using high-pressure jets that could damage the screen. Rinse until the water runs clear.
Tip: If odors persist, soak the filter briefly in warm water with a small amount of mild detergent. - 6
Clean the housing and seal
Wipe the filter housing and the gasket area with a damp cloth to remove any remaining debris. Dry all surfaces thoroughly to prevent mold growth.
Tip: Check for cracks or wear around the seal and address promptly. - 7
Reinstall the filter and cover
Place the cleaned filter back into its recess, ensure it sits flush, and reinstall the cover securely. If there’s any resistance, double-check alignment.
Tip: Never force a misaligned filter; misalignment can cause leaks. - 8
Test the washer
Plug the unit back in, select a short empty cycle with hot water, and observe drainage and leaks. If everything runs smoothly, you’re done. If you see leaks, reassess the seal and filter placement.
Tip: Record the maintenance date for future reference.
