Washer Filter Basket Clogged

Many high-efficiency top-load washers include a small removable debris filter (sometimes called a filter basket) inside or near the top of the drum, separate from the drain pump filter, designed to catch lint, hair, and small items that would otherwise circulate with the load or clog the drain path further downstream.

A clogged filter basket rarely stops the washer outright; instead it shows up as gradually worse symptoms -- lint sticking to dark clothes, a musty smell, slower draining than usual, or a rattling sound as trapped debris moves during the spin cycle.

Not every washer model has a visible filter basket in the drum; if you cannot find one after checking your owner's manual, your model likely routes all debris filtering through the drain pump filter instead, and you should check the drain pump clogged guide.

Safety first. Washer repair involves electricity, water under pressure, and moving mechanical parts.

Take a photo of any wiring or hose routing before disconnecting it, and set screws and small parts aside in the order removed -- this alone prevents most reassembly mistakes.

Most Likely Causes

  1. Lint and hair accumulation — The most common cause on any model that has this filter; fine lint and pet hair mat together over repeated loads. How to check: locate the filter (check your owner's manual for its exact position, often at the top of the agitator or along the tub rim) and remove it to inspect for a dense buildup.
  2. Small items trapped in the filter — Buttons, coins, and bra underwires get caught the same way they do in a drain pump filter, but in this filter they can also rattle audibly during spin since they sit closer to the drum wall. How to check: empty pockets and check for a rattling sound during spin before assuming a mechanical part has failed.
  3. Filter not reinstalled correctly after cleaning — A filter basket that is not seated and locked back in place after cleaning can rattle, vibrate, or let debris bypass it entirely. How to check: remove and reinsert the filter, confirming it clicks or locks fully into place per your model's design.
  4. Filter housing cracked or filter itself damaged — Less common: a cracked filter frame lets debris pass around rather than through it, so the filter looks clean even though debris is still reaching the drum and drain path. How to check: inspect the filter frame and mesh for cracks or tears, holding it up to light.

How Filter Clogging Connects to Other Symptoms

A clogged filter basket is frequently the real cause behind complaints that look like other symptoms on this site -- a musty smell, a rattling noise during spin, or draining that has gradually slowed rather than stopped outright. Checking this filter takes a few minutes and no tools on most models, so it is worth ruling out before working through the more involved causes on the odor, noise, or drain pump pages.

Tools You Will Need

Most of the checks on this page use the same basic kit: a Phillips and flat-head screwdriver set for opening panels, a multimeter set to continuity/ohms for testing switches and motor windings, a flashlight for looking inside the cabinet, needle-nose pliers for hose clamps and small connectors, and a shallow pan with a towel for any step that involves disconnecting a hose or opening the pump filter access door. None of the checks above require specialty tools. Photograph any wiring harness or hose routing before disconnecting it so reassembly matches exactly, and keep screws grouped by the panel they came from rather than in one pile -- washers use several different screw lengths, and mixing them up is a common cause of a rattle appearing right after a repair.

When to Call a Professional

Most of the parts and checks covered on this page are within reach of a confident DIY repair with basic hand tools and an afternoon. Call a licensed appliance technician instead if a check requires working inside a sealed system, if you find damaged household wiring beyond the washer's own power cord, or if the suspected part sits behind a transmission or tub assembly that requires substantially disassembling the cabinet and you are not comfortable reassembling it correctly. A second, paid diagnosis is also worth it any time you have already replaced one suspected part and the exact same symptom returns.

How to Confirm Before You Buy

Before ordering any replacement part, take a minute to confirm the fit -- it is the difference between a repair that works the first time and a part that has to be looked up twice.

  1. Find the model/serial plate. On a top-load washer it is usually under the lid, along the rim of the tub opening. On a front-load washer, check the back panel or around the inside of the door opening. See how to find your model number for exact locations by appliance type.
  2. Read the full model number exactly as printed, including letters and dashes -- manufacturers often reuse near-identical model numbers across different production years that take different parts.
  3. Verify the part fits that model using our model and part lookup tool before ordering, rather than relying on a part looking similar to the one you are replacing.

The full model number matters more than the brand and appliance type alone: manufacturers commonly reuse one body design across many model numbers over several years, changing the exact door latch, control board, or pump partway through that run. Two washers that look identical sitting side by side can still take different parts if their model numbers differ, even by a single trailing letter or digit.

Check Your Exact Model

Part numbers and how a symptom shows up can vary even within the same brand and appliance type, so confirm your exact model before ordering anything. Start from one of these washer model pages, or look yours up directly:
