Why Does My Washing Machine Shake Violently During the Spin Cycle?

Updated August 1, 20263 min readTime needed: 15–20 minutes

Short answer: Violent shaking during spin is almost always an unbalanced load or unlevel feet, both fixable in minutes. If leveling and load balance don't help, worn suspension springs or shock absorbers (front-loaders) or a worn snubber pad (top-loaders) are the next most likely cause.

Common Symptoms

Loud banging or shaking specifically during the spin cycle
The machine visibly rocks or 'walks' across the floor
Shaking is worse with large or single-item loads
Vibration transmits noticeably through the floor to other rooms

Likely Causes

1. Unbalanced load

Clothes bunched to one side of the drum throw off the spin balance, which is the single most common cause of violent shaking.

2. Unlevel machine

If the washer isn't sitting level on all four feet, it has less stability to absorb the natural forces of a high-speed spin.

3. Shipping bolts still installed (new machines)

New washers ship with bolts that lock the drum in place for transport — leaving them in after installation causes severe shaking and can damage the machine.

4. Worn suspension springs or shock absorbers

Front-loaders suspend the drum on springs or shocks that wear out over years of use, reducing their ability to absorb spin vibration.

5. Worn snubber pad or ring (top-loaders)

Many top-loaders use a friction pad to dampen basket movement; once it wears down, the basket can bang against the cabinet during spin.

Safe Checks You Can Do

Confirm all shipping bolts were removed if this is a newly installed machine — check the installation manual for their exact location.
Use a level placed on top of the machine to check it's sitting flat front-to-back and side-to-side.
Check that all four feet are firmly on the floor and not rocking, and that adjustable feet are locked with their locknuts.
Redistribute the load and run a spin-only cycle to see if shaking improves.

Step-by-Step Solution

1
Remove shipping bolts if present
For a new install, locate and remove all transport/shipping bolts per the manual — this alone resolves severe shaking in new-machine installs.
2
Level the machine
Adjust the leveling feet until a level reads flat in both directions, then tighten the locknuts against the cabinet to hold the adjustment.
3
Rebalance the load
Redistribute bunched laundry evenly, especially with single bulky items like comforters, and re-run the cycle.
4
Check the floor surface
A flexible or uneven floor (some wood subfloors) can amplify vibration even with a level, balanced machine — a rubber anti-vibration mat can help in this case.
5
Inspect suspension components if shaking persists
On front-loaders, this typically means checking the suspension springs/shocks; on top-loaders, it means checking the snubber pad or ring — both usually need a technician to access safely.

What Not to Do

Don't run a machine that's actively walking across the floor unattended — stop it and address the cause first.
Don't skip removing shipping bolts hoping 'it'll be fine' — running with them installed can cause real damage.
Don't overcompensate leveling by over-tightening one foot — adjust gradually and recheck with a level each time.

When to Call a Professional

The machine is level, the load is balanced, and shaking is still severe.
You hear a metallic banging or scraping sound distinct from normal spin noise.
The machine has visibly shifted or 'walked' several inches from its original position.
This is an older front-loader and you suspect worn suspension springs or shocks.

Safety warning

A washer that shakes hard enough to move across the floor can pull its water and drain connections loose, causing a leak. Stop the machine and unplug it if shaking is severe rather than letting the cycle finish.

Frequently Asked Questions

Is it normal for a washer to shake a little during spin?

A small amount of vibration is normal, especially at high spin speeds. Violent shaking, banging, or the machine moving across the floor is not, and should be addressed rather than ignored.

Can an uneven floor cause shaking even if the machine is level?

Yes — a flexible floor, especially over a wood subfloor, can amplify normal vibration into noticeable shaking. An anti-vibration mat under the machine's feet often helps in this situation.

How do I know if my shipping bolts are still in?

Check your installation manual for their exact location (usually on the back panel) — leaving them in is one of the most common causes of severe shaking in a newly delivered washer.
