If your washing machine shakes, moves, or bangs loudly during the spin cycle, the problem is often related to balance, installation, or worn suspension components.
Some movement is normal during high-speed spinning, but violent shaking should not be ignored.
Here are seven common reasons a washing machine may shake excessively.
1. The Load May Be Unbalanced
An uneven load is one of the most common causes of shaking.
Heavy items such as:
- Towels
- Blankets
- Jeans
- Bedding
- A single large item
can collect on one side of the drum.
Pause the cycle, redistribute the laundry evenly, and try the spin cycle again.
2. The Washing Machine May Not Be Level
The washer should sit firmly on all four feet.
If one corner is higher or lower than the others, the machine may rock during spinning.
Check whether:
- The machine moves when pushed
- One foot is not touching the floor
- The washer leans to one side
Adjust the leveling feet according to the manufacturer’s instructions.
3. The Floor May Be Uneven or Flexible
Even a properly leveled washer may shake if the floor underneath is unstable.
Possible problems include:
- Uneven flooring
- Flexible wooden floors
- Loose tiles
- Soft surfaces
A solid, level surface provides the best support.
4. Shipping Bolts May Still Be Installed
Front-loading washing machines often use shipping bolts to hold the drum in place during transport.
If these bolts are not removed after installation, the machine may shake violently.
This is especially important if the washer is:
- Newly installed
- Recently moved
- Recently delivered
Check the installation manual to confirm whether shipping bolts should have been removed.
5. The Washer May Be Overloaded
Too much laundry can make it difficult for the drum to balance.
An overloaded machine may:
- Shake
- Bang
- Stop spinning
- Show an error code
- Move across the floor
Remove some items and try a smaller load.
6. Suspension Components May Be Worn
Washing machines use parts such as:
- Shock absorbers
- Suspension rods
- Springs
to control drum movement.
If these parts wear out, the drum may move excessively during spinning.
Possible signs include:
- Repeated banging
- Excessive drum movement
- Shaking even with balanced loads
- Machine becoming louder over time
These parts may require professional replacement.
7. The Drum or Counterweight May Be Loose
Some washers use heavy counterweights to stabilize the drum.
If a counterweight or drum component becomes loose, the machine may produce severe shaking or knocking.
This is more serious and generally requires professional inspection.
What Should You Check First?
Before arranging service:
- Redistribute the laundry
- Remove excess items
- Make sure all four feet touch the floor
- Check that the washer is level
- Confirm shipping bolts were removed
- Test the machine with a small balanced load
When Should You Stop Using the Washer?
Stop using the machine and arrange inspection if:
- The washer moves across the floor
- Loud banging continues with small loads
- The drum appears loose
- You hear metal-on-metal noises
- The machine leaks while shaking
- The washer was recently moved and now shakes severely
When Should You Call a Technician?
Consider professional service if:
- Leveling does not solve the problem
- Suspension parts appear worn
- The drum moves excessively
- Counterweights may be loose
- The machine shakes even when empty
- Loud banging continues
FAQ
Why does my washing machine shake only during spin?
High-speed spinning makes load imbalance and leveling problems more noticeable.
Can an overloaded washer shake violently?
Yes. Too much laundry can prevent the drum from balancing properly.
Can shipping bolts cause severe vibration?
Yes. If shipping bolts are left installed, a front-loading washer may shake violently during use.
Why does my washer move across the floor?
The machine may be unbalanced, improperly leveled, overloaded, or have worn suspension parts.
Is some vibration normal?
Yes. Mild vibration during high-speed spinning can be normal, but violent shaking or repeated banging should be investigated.

*** If water is leaking while the machine shakes, see why your washing machine is leaking water.
*** If water remains in the drum after the cycle, read why your washing machine is not draining.
