How to Fix a Washing Machine That Doesn’t Remove Lint Properly
A washing machine that fails to remove lint can be frustrating, especially when clothes come out covered in unwanted fibers. This problem can be caused by clogged filters, incorrect detergent usage, or even plumbing issues. Fortunately, there are several troubleshooting steps you can take to fix the issue.
Understanding How Lint Removal Works in a Washing Machine
Lint is made up of small fibers that shed from clothes during washing. Most modern washing machines have a lint filter or a pump system that traps these fibers, preventing them from redepositing onto clothing. Some machines rely on the water drainage system to flush lint out, while others use an agitator-based system with a dedicated lint trap.
When lint remains on clothes after a wash cycle, it often indicates a problem with one of these systems. Identifying the root cause will help you fix the issue effectively.
Common Causes of Poor Lint Removal
1. Clogged Lint Filter
Many top-loading washing machines have a lint filter inside the agitator or near the drum. If this filter becomes clogged, it will not capture lint effectively.
2. Insufficient Water Flow
Low water levels or reduced water pressure can prevent proper rinsing, allowing lint to stay on clothes.
3. Detergent Issues
Using too much detergent can create excess suds, which trap lint and prevent it from being rinsed away. Conversely, using too little detergent can leave clothes insufficiently cleaned.
4. Dirty Drain Pump Filter
Front-loading washing machines often have a drain pump filter that catches debris, including lint. If this filter is blocked, water may not drain properly, leading to lint buildup on clothes.
5. Hard Water Deposits
Mineral deposits from hard water can reduce the efficiency of detergent and fabric softeners, causing lint to cling to clothes instead of being washed away.
6. Worn or Faulty Washer Components
A damaged lint filter, malfunctioning pump, or defective drum movement can contribute to poor lint removal.
How to Fix a Washing Machine That Doesn't Remove Lint Properly
Step 1: Clean the Lint Filter
- Check your washing machine’s manual to locate the lint filter.
- Remove the filter and rinse it under warm water.
- Use an old toothbrush to scrub away any buildup.
- If the filter is damaged, replace it with a new one.
For models without a visible lint filter, refer to the manufacturer’s instructions to see if there is a hidden lint trap.
Step 2: Inspect and Clean the Drain Pump Filter
- Front-load washers usually have a drain pump filter located behind a small access panel at the bottom.
- Turn off the washer and unplug it.
- Open the access panel and unscrew the filter.
- Rinse it thoroughly and remove any lint or debris.
- Reinstall the filter securely before turning the washer back on.
Step 3: Adjust Water Levels and Temperature
- Use the highest water level setting when washing heavily lint-producing clothes like towels or fleece garments.
- Warm or hot water can help dissolve detergent and remove lint more effectively.
Step 4: Use the Right Detergent and Amount
- If using high-efficiency (HE) washers, always use HE detergent.
- Avoid using excessive detergent, as it can trap lint in suds.
- Consider adding a cup of white vinegar to the rinse cycle to break down detergent residue and loosen lint.
Step 5: Maintain the Washer Drum
- Wipe down the drum with a damp cloth to remove any accumulated lint.
- Run an empty cycle with hot water and a washing machine cleaner or a mixture of vinegar and baking soda to eliminate residue.
Step 6: Check and Clean the Drain Hose
- A partially clogged drain hose can reduce the water flow, preventing lint from being flushed out.
- Disconnect the drain hose and flush it with warm water.
- Ensure the hose is not kinked or bent, as this can also restrict water drainage.
Step 7: Use a Lint Catcher in the Drain Hose
- If your washing machine drains into a sink or standpipe, installing a lint catcher on the drain hose can prevent lint from clogging the drainage system.
Step 8: Reduce Lint Production
- Wash lint-producing fabrics (e.g., towels, sweaters, and fleece) separately from smooth fabrics.
- Turn clothes inside out to minimize shedding.
- Clean your dryer’s lint trap after every use to prevent lint from transferring back onto washed clothes.
When to Call a Professional
If you have tried all the above steps and your washing machine is still not removing lint properly, you may need professional repair services. Signs that indicate a more serious issue include:
- Persistent lint buildup despite cleaning the filters.
- Slow or incomplete draining after a wash cycle.
- Unusual noises or vibrations during operation.
- Water leaks from the washer.
A technician can inspect components such as the pump, drum bearings, or control board to diagnose and fix the issue.
