How to Clean Your LG Washer Filter

Understanding Your LG Washer Filter System

LG washing machines include filter systems designed to trap lint, debris, and foreign objects before they reach the drain pump. Most LG front-load washers have two filters: a drain filter and a pump filter. The drain filter catches larger items like coins, buttons, and fabric pieces, while the pump filter prevents smaller particles from clogging the drainage system. Understanding where these filters are located and how they function helps you maintain your washer's performance over time.

The drain filter in LG washers is typically located behind a small access panel at the bottom of the machine's front. This is the filter you'll clean most frequently—usually every one to three months, depending on how often you use your washer. The pump filter sits deeper within the drainage assembly and may require more involved access. Some LG models combine these into a single filter unit, while others keep them separate. Checking your specific model's manual will clarify which configuration your machine uses.

Filters accumulate debris gradually. Over time, buildup reduces water drainage speed, can cause unpleasant odors in the drum, and may trigger error codes on your washer's display. Regular filter maintenance prevents these issues and extends your machine's lifespan. When water drains slowly after a wash cycle or you notice a musty smell coming from the machine, these are signs that filter cleaning is overdue.

LG designs these filters to be cleaned by the owner without requiring special tools or professional service. The process takes about 15 to 30 minutes and costs nothing beyond water and perhaps a cleaning cloth. By learning this maintenance task, you can keep your washer running smoothly and avoid potential repair expenses.

Practical takeaway: Locate your washer's filter access panel today and note the location. Check your owner's manual to determine if your model has one or two filters and their exact positions.

Tools and Materials You'll Need

Cleaning your LG washer filter requires only basic household items that you likely already own. You don't need to purchase specialized cleaning equipment or expensive products. A few simple materials will allow you to complete the task thoroughly and effectively.

Start by gathering a bucket or large bowl—this catches water that drains from the filter housing when you open the access panel. Use a standard plastic bucket, mixing bowl, or even a large plastic storage container. The bucket should hold at least two to three quarts of water. Have towels or rags nearby to absorb any spills. Old towels work perfectly for this purpose since water may soil them during the cleaning process.

You'll need a soft-bristled brush or old toothbrush to scrub away lint and debris from the filter mesh. The soft bristles clean effectively without damaging the filter material. A flashlight or smartphone light helps you see inside the filter housing clearly, especially if your washer's location lacks bright overhead lighting. Warm water is your primary cleaning agent—you can run your filter under the sink faucet or use water from your bucket. For stubborn buildup, white vinegar works well as a natural cleaning agent without harsh chemicals.

Optional but helpful items include rubber gloves to keep your hands clean, a small flashlight if your phone doesn't have a light function, and a cleaning cloth for drying the filter after washing. Some people find needle-nose pliers or tweezers useful for removing larger debris like coins or buttons before washing the filter, though this isn't required.

Practical takeaway: Assemble a small cleaning kit and store it near your washer. Include a bucket, old towel, soft brush, and flashlight so these materials are ready when you need them.

Step-by-Step Filter Removal and Inspection

Removing your LG washer filter begins with preparing the area around your machine. Unplug the washer from the electrical outlet or turn off the power using the circuit breaker. This safety step prevents accidental starting during the cleaning process. Wait a few minutes after the wash cycle ends to allow any remaining water in the system to drain naturally. Position your bucket on the floor beneath the filter access panel to catch water that will spill when you open it.

Locate the small door or access panel at the bottom front of your LG washer. Most models have a small notch or indentation that you push or twist to release the panel. Some panels are held by a single screw that you'll remove with a screwdriver. Open the panel carefully—water may still be present inside the housing. Place your bucket directly under the opening. You may see a small drain hose or emergency drain valve near the filter; some models allow you to drain remaining water by opening this valve first, which prevents a large spill when you access the filter itself.

Once the panel is open, look for the filter. In most LG front-load washers, the filter appears as a cylindrical cartridge with a handle or knob at the top. Grasp the handle firmly and turn it counterclockwise—typically one-quarter to one-half turn is sufficient. The filter should release easily from its housing. If it resists, apply steady pressure without forcing, as excessive force can damage the filter or housing threads. As you remove the filter, water will drain into your bucket, so keep the bucket positioned directly underneath.

Once removed, inspect the filter visually. You'll likely see lint, hair, and debris accumulated on the mesh surface. The amount of buildup indicates how often you need to clean the filter. Filters with heavy lint accumulation suggest cleaning every month, while those with light buildup may only need attention every three months.

Practical takeaway: Before cleaning, take a photo of how the filter sits in its housing. This visual reference helps you reinstall it correctly later.

Cleaning the Filter Thoroughly

With the filter removed, rinse it under warm running water at your sink. Hold the filter under the faucet with the mesh facing downward, allowing water to flow through and dislodge loose lint and particles. Rotate the filter as you rinse to ensure all surfaces are exposed to the water stream. This initial rinse removes most loose debris and typically takes about one to two minutes. For filters with moderate buildup, this may be sufficient, but heavier deposits require additional cleaning.

Use your soft-bristled brush to gently scrub the filter's mesh surface. Work in one direction, brushing from the top toward the bottom of the filter. Pay special attention to the ridges and grooves where lint accumulates. Brush the outer surface thoroughly, then flip the filter and brush the inner surface. The goal is to dislodge trapped lint without damaging the delicate mesh material. Avoid using hard-bristled brushes or scrubbing too aggressively, as this can tear the mesh and render the filter ineffective.

For stubborn buildup or hard water deposits, soak the filter in a bucket of warm water mixed with one cup of white vinegar for 15 to 20 minutes. The vinegar helps dissolve mineral deposits and kills odor-causing bacteria. After soaking, scrub gently with your brush and rinse thoroughly under clean running water. The vinegar smell will dissipate as the filter dries.

Inspect the filter against a light source to ensure all visible debris is removed. Look for lint trapped in the mesh holes and any discoloration indicating mineral buildup. Once the filter appears clean, place it on a clean towel to air dry while you clean the filter housing. If your schedule is tight, you can reinstall a slightly damp filter, but air drying is preferable to prevent moisture in the sealed housing.

Practical takeaway: Clean your filter over the sink or a bathtub to contain splashing water. If the filter doesn't look visibly cleaner after rinsing and brushing, soak it in vinegar water and try again.

Cleaning the Filter Housing

While your filter dries, clean the housing where it sits. This area accumulates lint and debris that can interfere with proper filter seating. Shine your flashlight into the filter housing to see what's inside. You'll likely notice lint and particles stuck to the walls of the chamber. Use a damp cloth or paper towel to wipe the interior surfaces, reaching as far as you can comfortably. A cloth wrapped around your finger helps you clean the sides and bottom of the housing.
