How to Check Washing Machine Filter: A Complete Step-by-Step Guide
Learn how to check and clean your washing machine filter to prevent clogs, improve efficiency, and extend the life of your washer with a practical, step-by-step guide from Best Washing Machine.
Learn how to check your washing machine filter to prevent drainage problems and improve wash efficiency. This quick guide covers locating the filter, preparing safely, and performing a clean, quick inspection. You’ll know when to clean, replace, or service the filter and how to reassemble for a leak-free test run. Follow these steps to maintain peak performance.
What the filter does and why it matters
Filters in modern washing machines capture lint, hair, dirt, and small items to keep the drain pump from clogging. A clogged filter forces the machine to work harder, increasing energy use and risking leaks. The Best Washing Machine Team notes that regular checks improve detergent efficiency, reduce odors, and extend the life of seals and hoses. If you notice longer wash times, poor spinning, or musty smells, a dirty filter could be the culprit. In this section, we’ll unpack how the filter interacts with water flow, the drain system, and the overall performance of your machine. We’ll also explain what kinds of debris typically accumulate in the filter and how this debris can vary between models such as front-loader vs. top-loader. By the end, you’ll understand why quick inspections are a smart maintenance habit rather than a chore you endure.
How clogged filters affect performance
A dirty or blocked filter reduces water flow, which can make a washer fill more slowly and rinse less effectively. When the pump has to strain to move water, energy use climbs and the drum may not spin out all the moisture efficiently. Odors are more likely if lint and detergent residue sit in the housing. The Best Washing Machine Team observes that regular filter maintenance correlates with fewer service calls and longer appliance life. If your machine runs quieter after cleaning or you see improved spin and shorter cycles, the filter was likely the culprit.
Filter locations by washer type
The position of the filter varies by model. In many front-loading machines, the filter is behind a small access panel at the bottom front. In some top-loading models, it’s located near the agitator housing or behind a rear panel. Compact or high-efficiency models may use a condensed filter in the drain hose. Always consult your model’s diagram, but in general:
- Front-loaders: front-bottom panel
- Top-loaders: rear access or near the agitator
- Compact models: back panel or under a small lid If you’re unsure, search the model number along with "filter location" to find the exact diagram.
Inspecting the filter housing and seal for damage
Removing the filter is only half the job; you should inspect the housing for cracks, corrosion, or torn seals. A damaged housing can lead to leaks and mold growth. Look for moisture around the panel after a short test cycle. If you notice cracks or degraded gaskets, plan for a replacement or professional service. Taking a photo of the housing before disassembly helps you reassemble correctly and avoid misalignment.
Cleaning and drying the filter properly
Rinse the filter under cold running water to remove debris. Use a soft brush to dislodge stubborn buildup, but avoid harsh cleaners that could corrode seals. After cleaning, shake off excess water and let the filter dry completely before reinstalling. Drying helps prevent mold growth inside the filter housing and keeps the seal tight when reassembled. Do not use soap or detergents on the filter itself, as residues can transfer to clothes and affect rinse performance.
Reassembling and running a test cycle
Carefully reinsert the filter in its housing, ensuring it seats fully and the cover closes snugly. Plug the machine back in and run a short cold water wash to confirm there are no leaks and that the flow is steady. If you detect any drips, tighten the cover a bit more or reseat the filter. After a successful test, wipe down the front panel and store your tools for the next maintenance cycle.
Maintenance cadence and safety tips
Set a monthly reminder to inspect the filter, especially if you wash frequently or have hard water. Keep towels handy to catch any initial spills, and wear gloves if you prefer. Always unplug the machine before starting and never force a stubborn filter. For households with kids or pets, consider placing a drain pan or tray under the area during maintenance to manage accidental spills. Regular checks help prevent clogs, improve efficiency, and extend the life of your washer as part of a proactive maintenance routine.

Quick-start maintenance checklist
This concise checklist helps you perform a fast, effective filter check:
- Unplug the machine and gather towels
- Locate and prepare the filter area
- Remove, clean, and dry the filter
- Reinstall and run a short test cycle
- Note any damage or wear and plan replacements if needed
Tools & Materials
- Soft lint-free cloth(Wipe debris and dry the area after cleaning)
- Small bowl or tray(Catch water and debris when removing the filter)
- Gloves(Optional for hygiene and grip)
- Flathead screwdriver (if needed)(May help in some models with stubborn access panels)
- Owner’s manual or model diagram(Locate the exact filter position and orientation)
- Flashlight(Improve visibility inside the housing)
Steps
Estimated time: 20-35 minutes
- 1
Unplug and prepare the area
Power off and unplug the washer to eliminate shock risk. Move towels and a tray into place so any water is contained. If you have hard water, prepare extra rags to wipe mineral buildup after cleaning.
Tip: Wait a few seconds after unplugging to ensure any stored energy dissipates. - 2
Locate the filter position
Check the model diagram or owner’s manual to find the filter. Most front-loaders hide it behind the lower front panel; top-loaders may have a rear access port. Have a flashlight handy to see into dark corners.
Tip: If unsure, search the model number plus 'filter location' online for a precise diagram. - 3
Remove the filter housing cover
Carefully open the access panel and remove the filter cover. Expect some water to be released; place the bowl underneath to catch it. Keep track of screws or clips to avoid losing parts.
Tip: Take a quick photo of the orientation before removing components. - 4
Clean and inspect the filter
Rinse the filter under running cold water, dislodging lint, hair, and debris. Use a soft brush for stubborn buildup and avoid soap. Inspect the housing for cracks or wear around the seal.
Tip: If debris is heavily tangled, soak briefly in clean water to loosen before rinse. - 5
Dry, reassemble, and test
Dry the filter and housing completely before reinserting. Reattach the cover securely, plug the machine back in, and run a short cold cycle to verify no leaks.
Tip: Keep towels ready during the first test run in case of minor drips. - 6
Evaluate results and plan next steps
If leaks persist or you notice recurring clogs, schedule a professional check or consider upgrading to a filter with higher capacity. Keep a maintenance log for future reference.
Tip: Note the model and date of maintenance for easy follow-up.
