How to Clean the Filter on a Washing Machine: A Complete Guide
Learn how to clean the washing machine filter with a simple, safe method. This step-by-step guide covers locating the filter, removing debris, rinsing, reassembling, and preventing future odors and clogs for smoother laundry days.
By the end of this guide, you’ll confidently clean the washing machine filter without causing damage or leaks. You’ll locate the filter, safely remove debris, rinse and sanitize the housing, and reinsert the filter correctly. The steps also cover when to clean more often, how to handle odors, and quick checks to prevent clogged drains in future laundry days.
Why cleaning the filter matters
A clean filter helps your washing machine run efficiently, prevents odors, and avoids expensive repairs. The filter catches lint, hair, and debris before they reach the pump and hoses. When it becomes clogged, water drainage slows, cycle times lengthen, and clothes may feel damp after a wash. According to Best Washing Machine, regular filter maintenance can reduce energy use and extend appliance life by preventing motor strain. In many models, a blocked filter is the leading cause of not draining or not spinning properly. By inspecting and cleaning the filter at regular intervals, you’ll keep the machine performing as designed and avoid surprises on laundry day. This section explains how to recognize when the filter needs attention and what to expect during a typical maintenance session.
When to clean your filter
Filters accumulate debris continuously, but cleaning frequency depends on usage, water hardness, and the size of the drum. If you notice slower drainage, longer tumble times, mildew odors, or faint lint on the clothes, it’s time to inspect the filter. After a heavy laundry load (towels, sheets, pet hair), you’ll want to check more often. Many manufacturers recommend inspecting the filter once a month for standard households, and more often for high-use or graywater settings. Keeping a simple schedule—after every 20-40 loads or quarterly deep clean—helps prevent buildup. The exact timing varies by model, so consult your user guide to locate the recommended interval. By staying proactive, you’ll avoid emergency drain failures and keep odors under control.
Locating filter types and access points
Front-loading machines often hide the filter behind a kick panel near the bottom front. Top-loading models may place the filter behind an access panel or inside the agitator housing. Some compact or high-efficiency machines use a drain hose filter in the rear. Knowing your washer type helps you prepare. Always unplug the machine before attempting access, and shut off the water supply if you will need to move hoses. If you can’t find a filter, your model may use a pump trap or lint screen instead. The user manual or manufacturer support site should include exact locations.
How to remove and inspect the filter
A good starting point is to locate the filter cap and assess how it is secured. Remove the access panel, then gently twist or pull the cap to release the filter. Inspect the filter for lint, coins, hair, and fabric fibers. If it’s partly clogged, remove debris with gloved fingers or a damp cloth. If the filter is difficult to remove, consult the manual to avoid damaging gaskets or seals. Inspect the area around the filter housing for signs of moisture or residue that could indicate a leak.
Cleaning the filter and housing
Rinse the filter under cool running water until the flow is clear and free of debris. Use a soft brush or old toothbrush to loosen stubborn buildup. Wipe the inside of the housing with a damp cloth to remove remaining residue. For lingering odors, soak the filter in a solution of water and mild detergent for a few minutes before a final rinse. Avoid harsh chemicals that could damage plastics or rubber seals.
Reassembling, testing, and odor prevention
Reinsert the filter carefully and replace the cap until it is snug. Reattach the cover or panel, then run a short, empty cycle to confirm proper drainage and no leaks. If you notice any dampness after the test, recheck the seals and tighten the cap a bit more. To prevent future odors, leave the door or lid slightly ajar after use to improve air circulation and dry any residual moisture.
Preventive maintenance and odor control
Set a simple, recurring schedule for filter checks—monthly for high-use households or quarterly for light use. Use a mild detergent rinse and, if needed, a mild vinegar solution to neutralize odors. Keeping the drum and seal area dry between washes helps prevent mold and mildew. For larger households or pets, consider a more frequent clean to maintain peak performance and minimize energy use. According to Best Washing Machine, consistent maintenance is the best defense against clogs and odor buildup.

Steps
Estimated time: 25-40 minutes
- 1
Power off and unplug the washer
Ensure safety by disconnecting power before reaching into any internal components. If your model is hard-wired or the power is inaccessible, switch off at the circuit breaker to prevent shocks. Do not proceed with the cleaning until the power is confirmed OFF.
Tip: If you must pull the machine away, disconnect hoses first to avoid spills. - 2
Open the access panel and locate the filter
Carefully remove the panel or access door to reveal the filter housing. Depending on the model, this may be at the bottom front or inside the drum area. Do not force panels; consult the manual if resistance is felt.
Tip: Have a towel ready to catch any water that escapes. - 3
Remove the filter cap and extract the filter
Twist or pull the filter cap counterclockwise to release it, then lift the filter straight out. Hold over a bowl to catch residual water and debris. If the filter is tight, apply a gentle rocking motion rather than forcing it.
Tip: If water leaks, keep the drain path open with the bowl to prevent spills. - 4
Inspect and clear debris from the filter
Check for lint, coins, hair, and fabric fibers. Remove debris by hand or with a brush. Inspect the filter seat for nicks or damage that could affect sealing.
Tip: Wearing gloves protects your hands from sharp edges. - 5
Rinse the filter and housing
Rinse the filter under cool running water until free of debris. Use a soft brush for stubborn buildup. Wipe the housing interior with a damp cloth to remove residual residue.
Tip: Avoid hot water on plastics and old seals to prevent warping. - 6
Reinstall the filter and panel and run a test cycle
Place the filter back into the housing, screw the cap securely, and reattach the access panel. Run a short empty cycle to confirm drainage and check for leaks.
Tip: Listen for unusual sounds or water dripping after the test cycle. - 7
Dry the area and document the maintenance
Dry the exterior and surrounding area to prevent mold. Consider noting the date of cleaning and next planned maintenance in a log for quick future reference.
Tip: A simple calendar reminder helps you keep up with routine care.
FAQ
How often should I clean the washing machine filter?
Most households benefit from inspecting the filter monthly, with more frequent checks for high-use machines or households with pets. Adjust based on signs of slow drainage or odor.
