KEY TAKEAWAYS

  • Regularly cleaning your LG washer's drain pump filter prevents inefficiencies and extends the appliance's lifespan.
  • Ignoring signs of a clogged filter can lead to costly repairs and diminished machine performance.
  • Scheduling yearly professional maintenance ensures your washer operates optimally and avoids preventable issues.

Understanding the Importance of an LG Washer Drain Pump Filter

The core responsibility of the drain pump filter in your LG washer is to protect the pump and drainage system from damage caused by lint and debris. This protection allows the washer to drain fully after each wash cycle. Neglecting the filter can lead to poor wash performance or costly repairs to the drain pump or drainage system. Regularly cleaning the filter mitigates these risks, promoting optimal function and saving on potential future expenses.

What It Does

The drain pump filter prevents debris, lint, and small items such as buttons and coins from entering the drain pump and clogging the drainage system. Over time, this debris can accumulate in the filter, impacting your washer's performance and potentially causing damage.

  • Prevents clogging: Keeps larger debris from blocking the drain hose.
  • Protects the motor: Reduces the risk of motor damage from obstructive objects.
  • Enhances efficiency: Promotes better water flow during cycles.

Signs That Your LG Washer Drain Pump Filter Needs Cleaning

Recognizing when your filter needs cleaning can save you from potential problems. There are some distinct signs to watch for.

  • Slow drainage: The washer takes longer than usual to drain.
  • Unusual noises: Sounds coming from the washer that suggest obstructions.
  • Error codes: Display of specific washer error codes that indicate drainage issues.

Why Routine Drain Pump Filter Cleaning is Important

Routinely cleaning the filter on your LG washer not only prolongs the life of your appliance but also boosts its performance.

  • Improved performance: Regular filter cleaning ensures your washer operates at peak efficiency.
  • Cost savings: Avoids costly repairs from clogged filters damaging the pump or motor.
  • Odor prevention: Helps prevent odors that can occur from stagnant water.

A Step-by-Step Guide to LG Washer Filter Cleaning

Cleaning the drain pump filter is a straightforward task that is easy to do. Because model designs vary, you should consult your owner's manual for detailed instructions.

  1. Unplug the washer to ensure safety, and make sure the tub is completely drained.
  2. Locate the access panel on the front or bottom of the washer. This panel allows access to the drain pump filter.
  3. Open the access panel by pulling the tab down and out. On some models, you may need to use a coin or a screwdriver to remove the screws or twist the cap counterclockwise to open the access panel.
  4. Place a shallow container underneath to catch drain water, and use towels to catch any spills.
  5. Pull the drain hose gently out, and place it in the container, then remove the plug from the end of the hose. Once the water is drained, remove the filter cap or pull out the filter, depending on your washer model.
  6. Remove any debris or lint trapped in the filter. You can use a soft brush on both sides, or rinse it under running water for a thorough LG washer filter cleaning. Inspect the housing for coins or other debris.
  7. Inspect the filter for any signs of damage or wear. If necessary, replace it with a new one.
  8. After cleaning or replacing, reinsert the filter into the drain pump and secure it by tightening the cap or twisting it clockwise.
  9. Close the access panel and tighten the screws or cap.
    By regularly practicing how to clean an LG washer drain pump filter, you'll help maintain your washer's efficiency and extend its lifespan. It's recommended to clean the filter every few months or whenever you notice any drainage issues. Keep your LG washer running reliably for years by following these steps.
