Introduction
A washing machine making loud, unusual noises can be alarming and may indicate serious problems. While some noise is normal during operation, loud banging, grinding, or thumping sounds often signal that something is wrong and needs attention.
Understanding what different washer noises mean helps you determine whether it’s a simple fix you can handle yourself or requires professional washer repair services. This guide covers common noise problems, their causes, and solutions.
Normal vs. Abnormal Washer Noises
Normal Sounds
- Low humming - Motor and pump operation
- Water filling sounds - Normal during fill cycle
- Gentle swishing - Water and clothes during wash
- Drain sounds - Normal during drain cycle
- Soft clicking - Normal operation sounds
Abnormal Sounds (Require Attention)
- Loud banging or thumping - Unbalanced load or mechanical problems
- Grinding or rumbling - Bearing or mechanical failures
- High-pitched squealing - Belt or bearing problems
- Metallic clanking - Foreign objects or component damage
- Excessive vibration - Installation or component issues
Common Causes of Loud Washer Noises
1. Unbalanced or Overloaded Load (Most Common)
An unbalanced load is the most common cause of loud banging and thumping sounds.
Why It Happens:
- Heavy items clustered on one side
- Too many clothes in the load
- Items wrapped around the agitator
- Uneven distribution
Symptoms:
- Loud banging or thumping during spin
- Washer may shake or move
- Noise increases during spin cycle
- May stop spinning due to imbalance
Solution:
- Stop the cycle immediately
- Redistribute clothes evenly
- Reduce load size
- Separate heavy items
- Restart the cycle
2. Worn Drum Bearings
Drum bearings support the drum and allow it to rotate. When they wear out, they cause loud grinding, rumbling, or banging sounds.
Why They Fail:
- Normal wear over time
- Overloading
- Age and degradation
- Lack of maintenance
Symptoms:
- Loud grinding or rumbling
- Especially during spin cycle
- Gets worse over time
- May feel vibration
Solution: Bearing replacement is a major repair requiring professional service. The washer must be disassembled to access bearings.
3. Foreign Objects in Washer
Items left in pockets or loose objects can cause loud metallic clanking or banging sounds.
Common Objects:
- Coins
- Keys
- Buttons
- Screws or nails
- Zippers hitting drum
Symptoms:
- Metallic clanking or banging
- May be intermittent
- Sounds during agitation or spin
- Related to specific loads
Solution:
- Check all pockets before washing
- Remove foreign objects from washer
- Inspect drain filter
- Check for items caught in drum
4. Worn Drive Belt (Top-Loading Washers)
A worn or damaged drive belt can cause squealing, grinding, or thumping sounds.
Why It Fails:
- Normal wear over time
- Overloading
- Age and degradation
- Improper tension
Symptoms:
- Squealing sounds
- Grinding during operation
- Thumping or slapping
- Belt visible through bottom panel
Solution:
- Inspect belt for wear or damage
- Check belt tension
- Replace if damaged
- Professional service recommended
5. Worn Suspension Springs
Suspension springs stabilize the drum. When they wear out, the drum can bang against the washer body.
Why They Fail:
- Normal wear over time
- Overloading
- Age and degradation
- Excessive vibration
Symptoms:
- Loud banging during spin
- Drum hitting washer body
- Excessive vibration
- Gets worse over time
Solution: Suspension spring replacement requires professional service due to disassembly needed.
6. Clogged Drain Pump Filter
A clogged drain pump filter can cause grinding or buzzing noises during the drain cycle.
Why It Happens:
- Foreign objects blocking filter
- Lint and debris buildup
- Not cleaned regularly
- Items caught in pump
Symptoms:
- Grinding or buzzing during drain
- May be intermittent
- Drain problems
- Related to drain cycle
Solution:
- Clean drain filter regularly
- Remove foreign objects
- Check pump area
- Clear blockages
7. Unlevel Installation
An unlevel washer can cause excessive vibration and noise.
Why It Happens:
- Improper installation
- Floor not level
- Leveling feet not adjusted
- Movement over time
Symptoms:
- Excessive vibration
- Banging against floor or walls
- Noise during operation
- Washer may move
Solution:
- Level the washer using leveling feet
- Use a level tool to check
- Adjust feet until level
- Test operation
8. Motor Bearing Problems
Worn motor bearings can cause high-pitched whining or grinding sounds.
Why They Fail:
- Normal wear over time
- Overloading
- Age and degradation
- Lack of maintenance
Symptoms:
- High-pitched whining
- Grinding sounds
- Gets worse over time
- May affect operation
Solution: Motor bearing replacement requires professional service.
Step-by-Step Troubleshooting
Follow these steps to diagnose and fix noise problems:
Step 1: Check Load Balance
First, check if the load is balanced:
- Stop the cycle if running
- Open the lid/door
- Redistribute clothes:
- Spread clothes evenly
- Separate heavy items

If this fixes it: The problem was load balance. Always load properly in the future.
Step 2: Check for Foreign Objects
Look for items causing noise:
- Check all pockets before washing
- Inspect washer interior:
- Look for visible objects
- Check drain filter
- Look in drum
- Remove any objects:
- Coins, keys, buttons
- Any foreign items
- Check drain pump area
- Test operation without objects
Step 3: Clean Drain Filter
Clear blockages causing noise:
- Locate drain filter:
- Usually at bottom front
- May be behind access panel
- Check owner’s manual
- Remove and clean:
- Remove filter carefully
- Clean thoroughly
- Remove all debris
- Check for foreign objects
- Replace and test:

- Check side to side
- Adjust leveling feet:
- Turn feet to adjust height
- Level in all directions
- Ensure all feet touch floor
- Test operation:
- Run a cycle
- Check for vibration
- Adjust if needed
Step 5: Inspect Drive Belt (Top-Loading)
Check belt condition:
- Access belt:
- Remove bottom panel if needed
