How to wash a washing machine filter?

Published in Appliance Maintenance 6 mins read

Washing your washing machine filter involves carefully removing it, clearing accumulated debris from both the filter and its housing, rinsing thoroughly, and then reinstalling it to ensure optimal machine performance and cleanliness.

Why Clean Your Washing Machine Filter?

Regularly cleaning your washing machine's filter is a crucial maintenance task that prevents a variety of common problems and extends the lifespan of your appliance. Neglecting this small part can lead to significant issues.

  • Prevents Odors: Lint, hair, and detergent residue trapped in the filter can create a breeding ground for mold and mildew, leading to unpleasant smells in your machine and on your clothes.
  • Improves Drainage: A clogged filter restricts water flow, causing poor drainage and potentially leaving your clothes excessively wet at the end of a cycle.
  • Enhances Cleaning Performance: When the filter is clean, the machine can circulate water and detergent more effectively, resulting in cleaner laundry.
  • Avoids Machine Malfunctions: Severe blockages can put a strain on your washing machine's pump and other components, potentially leading to costly repairs or even premature failure.
  • Reduces Vibrations and Noise: Debris can sometimes unbalance the machine or interfere with the pump, leading to increased noise and vibrations during operation.

When to Clean Your Washing Machine Filter

The frequency of cleaning largely depends on your usage habits. Generally, it's recommended to clean the filter:

  • Every 1 to 3 months: For average household use.
  • More frequently: If you wash heavily soiled items, pet blankets, or have pets that shed a lot.
  • Immediately: If you notice any of the following signs:
    • Unpleasant odors from the machine or clothes.
    • Water not draining properly.
    • Excessive lint or residue on washed clothes.
    • The machine stopping mid-cycle or displaying error codes related to drainage.

Step-by-Step Guide to Cleaning Your Washing Machine Filter

Cleaning your washing machine filter is a straightforward process that requires only a few simple tools and about 15-30 minutes of your time.

What You'll Need:

Tool Purpose
Shallow container To catch residual water that may drain out
Old towels/cloths To absorb spills and wipe down parts
Soft brush/toothbrush To gently scrub away stubborn debris from the filter and housing
Warm water For rinsing the filter
Protective gloves Optional, for hygiene

The Cleaning Process:

  1. Prepare the Area:

    • Unplug the Machine: For safety, always disconnect your washing machine from the power supply.
    • Locate the Filter: The filter (often called a "drain pump filter" or "coin trap") is typically found at the bottom front of the machine. It might be behind a small access panel or a removable kickplate. Refer to your washing machine's user manual if you can't find it.
    • Position Container and Towels: Place a shallow container or baking tray directly under the filter access point, along with old towels, to catch any residual water that will drain out.
  2. Drain Residual Water:

    • Most machines have a small drain hose next to the filter cap. Pull this hose out and remove its plug (if present) to allow any water trapped in the drum or pump to drain into your container. This step is crucial before removing the filter itself.
  3. Remove the Filter:

    • Once the water has largely drained, remove the filter from the housing by unscrewing it counter-clockwise. Be prepared for a small amount of additional water to spill out as you do this.
  4. Clean the Filter and Housing:

    • Clean out any debris that may have gathered both in the filter and the housing. This can include lint, hair, coins, buttons, and other small items.
    • Use your fingers to pull out large pieces of debris from the filter's mesh and from inside the filter housing.
    • For more stubborn residue, use a soft brush or an old toothbrush to gently scrub the filter under warm, running water. Pay attention to the grooves and crevices.
    • Wipe down the inside of the filter housing with a damp cloth to remove any slime or grime.
  5. Rinse Thoroughly:

    • Once you've rinsed the filter under warm water, ensure it's completely free of any remaining debris or soap scum. It should look visibly clean.
  6. Inspect and Reinstall:

    • Inspect the filter and its housing for any signs of damage, cracks, or wear. If anything looks broken, consider ordering a replacement part.
    • Place it back in the housing by screwing it clockwise until it's securely tightened. Do not overtighten, but ensure it's snug to prevent leaks.
    • Close the small drain hose (if applicable) and reattach any access panels or kickplates.
  7. Final Check:

    • Plug the washing machine back into the power outlet.
    • Run a short rinse or spin cycle without any clothes. This helps flush out any remaining debris and checks for leaks around the newly installed filter. If you notice any leaks, immediately unplug the machine and re-tighten the filter.

Tips for a Thorough Clean

  • Don't Use Harsh Chemicals: Stick to warm water and a soft brush. Harsh chemicals can damage the filter material or the machine's internal components.
  • Check for Damage: While cleaning, inspect the rubber gasket or seal around the filter for cracks or hardening. A damaged seal can cause leaks.
  • Consider a Maintenance Wash: After cleaning the filter, running a hot maintenance wash with a washing machine cleaner or white vinegar can further sanitize the drum and hoses, enhancing overall cleanliness. Learn more about washing machine maintenance for a spotless machine.

Maintaining Your Washing Machine Filter

Proactive habits can significantly reduce the frequency and intensity of filter cleaning:

  • Check Pockets: Always check clothing pockets before washing to prevent coins, tissues, and other small items from entering the filter.
  • Shake Off Excess Debris: For heavily soiled items or pet bedding, shake off loose dirt, hair, and lint outdoors before putting them in the washer.
  • Use the Right Detergent Amount: Overuse of detergent can lead to excessive suds and residue, which can contribute to filter clogging. Follow manufacturer recommendations.

By consistently following these steps and tips, you can maintain a clean, efficient washing machine, ensuring your laundry comes out fresh and your appliance operates smoothly for years to come.
