Quick answer
A washer making noise while washing is often due to an unbalanced load or a worn-out part. Check for unevenly distributed laundry, ensure the washer is level, and inspect for loose components. If the noise persists, replace the problematic part.
Confirm the symptom
- Noise occurs during the wash cycle, not the spin cycle
- The sound is loud and consistent or rhythmic
- The washer vibrates excessively during washing
Tools and prep
- Screwdriver (Phillips and flathead)
- Adjustable wrench
- Towel or mat for stabilizing the washer
- Flashlight for inspection
- Owner’s manual for model-specific guidance
- Plug in a surge protector if using electrical tools
Step-by-step troubleshooting
- Check Load BalanceDo: Pause the washer and redistribute the laundry evenly.Observe: Noise stops or decreases significantly.Means: The noise was caused by an unbalanced load.Next: Continue the wash cycle and monitor for recurrence.
- Inspect Washer LevelDo: Use a level to check if the washer is sitting evenly on the floor.Observe: Washer is tilted or wobbling.Means: An unlevel washer can cause noise and vibration.Next: Adjust the feet until the washer is level.
- Secure Loose ComponentsDo: Tighten all visible bolts and screws on the washer’s base and drum.Observe: Loose parts were found and tightened.Means: Loose hardware can cause rattling or knocking sounds.Next: Restart the washer and listen for the noise.
- Remove Foreign ObjectsDo: Check the drum and filter for small items like coins or buttons.Observe: Foreign objects are found and removed.Means: Objects trapped in the drum can create noise.Next: Run a test cycle to see if the noise is gone.
- Inspect Drum BearingsDo: Listen closely for a grinding or squealing noise from the drum area.Observe: A continuous grinding or squealing sound is heard.Means: Worn drum bearings may need replacement.Next: Consult the owner’s manual for bearing replacement instructions.
- Check Suspension SystemDo: Look for damaged or worn suspension springs or shock absorbers.Observe: Springs are stretched, broken, or shock absorbers are leaking.Means: A faulty suspension system can cause excessive vibration and noise.Next: Replace the damaged suspension parts.
- Test with an Empty LoadDo: Run the washer with no clothes to isolate the noise source.Observe: Noise still occurs without a load.Means: The issue is likely internal, such as a faulty motor or pump.Next: Check the motor and pump for issues.
- Inspect Motor and PumpDo: Listen for unusual noises from the motor or pump during operation.Observe: A loud humming, clicking, or grinding noise is heard.Means: The motor or pump may be failing.Next: Replace the faulty motor or pump component.
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
| Unbalanced Load Clothes are unevenly distributed, causing the drum to vibrate and make noise. | Common | Easy | None |
| Worn Drum Bearings Over time, drum bearings can wear out, causing grinding or squealing noises. | Sometimes | Medium | Drum bearings |
| Loose or Missing Bolts Loose hardware can cause rattling or knocking sounds during operation. | Common | Easy | Bolts and screws |
| Foreign Objects in Drum Small items like coins or buttons can get caught and create noise. | Sometimes | Easy | None |
| Unlevel Washer A washer that is not level can vibrate excessively and make noise. | Common | Easy | Adjustable feet |
| Faulty Suspension System Damaged suspension springs or shock absorbers can cause vibration and noise. | Sometimes | Medium | Suspension springs or shock absorbers |
| Failing Motor or Pump A malfunctioning motor or pump can produce loud humming, clicking, or grinding noises. | Rare | Hard | Motor or pump |
Parts matching
If your washer is making noise while washing and requires a part replacement, match your symptom to the most likely part:
- Unbalanced load or unlevel washer: No part needed; adjust load or level
- Loud grinding or squealing: Drum bearings
- Rattling or knocking: Bolts or loose components
- Vibrating and wobbling: Adjustable feet or suspension system
- Loud humming or clicking: Motor or pump
Always refer to your owner’s manual for model-specific part numbers and installation instructions.
When to call a professional
- The noise persists after checking all common causes
- You identify a worn motor or pump but lack the tools or experience to replace it
- The washer is under warranty and you don’t want to risk voiding it
- You hear a burning smell or notice sparks during operation
- The washer leaks water while making noise, indicating a more complex issue
