Washing machine lint clogs drains experts warn
Prevent costly repairs by cleaning your washing machine lint filter regularly to avoid clogged drains and damage.
A surprising number of people don’t realize washing machines collect lint, hair, and debris—enough to clog drains, damage pumps, and leave clothes covered in fuzz. Unlike dryers, washers lack a dedicated lint trap. Instead, they depend on a drain pump filter that, if ignored, causes slow drainage, foul odors, and mechanical failure.
Where to find the filter
The filter’s location varies by machine type and brand. Front-load washers usually have a small hatch near the bottom front, often on the left or right side. Opening it exposes an emergency drain tube and a twist-off filter cap. Top-load models may place the filter inside the agitator or along the tub’s rim.
If the location isn’t clear, consult the user manual. A few models don’t include a removable filter, using a mesh screen inside the drain hose instead.
What happens if you skip cleaning
Ignoring the filter doesn’t cause fires, but it creates other issues. Lint and debris accumulate in the pump, hoses, and tub seal, leading to blockages. Clothes emerge dirtier, coated in lint and hair. Water drains slowly or not at all, triggering error codes. Over time, the pump strains, increasing the risk of failure.

Trapped wet lint also supports mold and bacteria, producing a sour smell that transfers to laundry. In extreme cases, the washer may leak or refuse to start.
Some homeowners install an external lint trap on the drain hose for added protection. These mesh filters catch debris the washer’s system misses but also need regular cleaning.
How often to clean the filter
Manufacturers suggest cleaning the filter every one to three months. Homes with pets, heavy laundry loads, or frequent use should do it monthly. The task takes less than 10 minutes but prevents hours of troubleshooting later.
If the machine drains slowly or smells musty, check the filter right away. Waiting until the washer stops mid-cycle—leaving a tub full of water—is too late.

Cleaning a front-load washer filter
Unplug the machine first. Place a towel and shallow tray beneath the filter panel to catch water. Open the hatch, pull out the emergency drain tube if present, and let the water drain. Unscrew the filter cap and remove the filter. Rinse it under warm water, clearing all debris. Soak it in a 50-50 mix of warm water and vinegar for 15 minutes to dissolve soap scum and kill bacteria. Reinstall the filter, close the panel, and plug the washer back in.
Cleaning a top-load washer filter
Begin by unplugging the machine. If the filter sits inside the agitator, remove the cap and pull out the mesh cylinder. For filters along the tub rim, snap out the plastic strip. Rinse the filter under warm water, removing all lint and hair. Soak it in a vinegar solution for 15 minutes before reinstalling. Plug the washer back in once finished.
A few top-load models don’t have a removable filter. For those, run a cleaning cycle with vinegar or a washing machine cleaner to flush out debris. If problems continue, check the drain hose for blockages.
Regular maintenance keeps the washer running smoothly and extends its life. The task is minor but yields significant benefits—often overlooked until the machine fails.
