Why Is My Washing Machine Shaking Violently?
A washing machine that shakes violently, especially during the spin cycle, is usually caused by an unlevel installation, an unbalanced load, worn suspension components, or shipping bolts that were never removed after delivery. In more serious cases, worn drum bearings or shock absorbers can be the culprit.
Common Reasons Your Washer Is Shaking
Unlevel Installation
If a washer isn’t sitting perfectly level on the floor, even small imbalances can be dramatically amplified during high-speed spinning, causing the entire machine to rock or shake.
Unbalanced Load
A load that’s unevenly distributed — often from a single bulky item like a comforter — creates uneven weight distribution inside the drum, which can cause significant shaking during spin.
Shipping Bolts Not Removed
Many washers, especially front-load models, ship with bolts that secure the drum during transport. If these bolts aren’t removed during installation, the drum can’t move freely as designed, causing severe vibration.
Worn Shock Absorbers or Springs
Front-load washers use shock absorbers, and top-load washers often use springs, to dampen drum movement during the spin cycle. As these components wear out, they lose their ability to absorb vibration effectively.
Worn Suspension Rods
Suspension rods help stabilize the tub inside the washer’s housing. When they wear out or break, the tub can move more than it should, leading to noticeable shaking.
Worn Drum Bearings
Bearings allow smooth rotation of the drum. As they degrade, they can cause increasingly rough, shaky movement, often accompanied by a grinding or rumbling noise.
Uneven Floor Surface
Even a perfectly functioning washer can shake excessively if it’s placed on an uneven or unstable floor surface, particularly in older homes or laundry rooms with sloped flooring.
What You Can Check Yourself
- Use a level to check that the washer sits evenly on the floor, adjusting the leveling feet as needed
- Redistribute the load if it seems concentrated on one side of the drum
- Confirm that all shipping bolts were removed if the machine was recently installed
- Check that the washer isn’t touching adjacent walls or cabinets, which can amplify vibration noise
When You Should Call an Appliance Repair Technician
If leveling the machine and adjusting the load don’t resolve the shaking, or if you notice grinding noises alongside the vibration, worn suspension components, shocks, or bearings are likely at fault and should be inspected by a professional.

Frequently Asked Questions
Is it normal for a washer to shake a little during spin?
A small amount of movement can be normal, but violent shaking or the machine moving across the floor is not.
Can an uneven floor really cause a washer to shake this much?
Yes — even a properly functioning washer can shake significantly if it isn’t sitting level and stable.
What happens if shipping bolts are never removed?
The drum can’t move as intended, which can cause severe vibration and, over time, damage to internal components.
Is a shaking washer likely to cause damage if I keep using it?
Yes — prolonged excessive vibration can accelerate wear on suspension components, bearings, and even the washer’s frame.
How do I know if my leveling feet need adjustment?
If the washer rocks when you press down on each corner, the leveling feet likely need adjustment to create a stable, even base.
