Why does my washing machine shake and walk?
Updated August 2026
A washer that shakes hard and walks across the floor is nearly always fighting an unbalanced load or a machine that is not level. During spin the drum turns at 800–1,200 rpm, and a lopsided load or a foot that does not sit flat turns that speed into a violent wobble. Redistribute the clothes and level the machine with a bubble level, both free, before suspecting anything internal. If it still shakes on a balanced, level machine, the causes below take over.
Safety first: a washer that walks is a water-damage and appliance-safety risk, because a machine sliding across the floor can stretch or rip its fill hoses and pull the drain hose out of the standpipe, flooding the room. Make sure the hoses have slack and the supply valves are reachable. On a raised pedestal or an upper floor, a violently shaking machine can also work loose, so stop the cycle and rebalance rather than letting it pound.
Causes, most likely first
| Cause | How likely | The fix | Typical cost |
|---|---|---|---|
| Unbalanced or bunched load | Most common | Stop the spin and spread heavy items evenly around the drum. Wash a single bulky item like a rug with a few towels. | Free |
| Unlevel machine or un-adjusted feet | Common | Level it front-to-back and side-to-side with a bubble level, adjust the leveling feet, and tighten their lock nuts. | Free |
| Shipping bolts still installed (new front-loaders) | Common | A new machine will shake hard until the 3 to 4 transit bolts on the back are removed. | Free |
| Worn suspension springs or shock absorbers | Occasional | Worn dampers let the drum swing freely. Replace the shocks or springs as a set. | $50–200 |
| Worn drum or tub bearings | Occasional | A loud rumble or grinding on spin, plus play in the drum, points at failed bearings. Replace the bearing set. | $200–400 |
Check these first
- Stop the spin and redistribute the load, spreading bulky items evenly so no single item is bunched to one side.
- Set a bubble level on top of the machine front-to-back and side-to-side, and adjust the leveling feet until it sits flat.
- Push down on each corner: any rocking means a foot is not making contact and needs adjusting.
- On a machine less than a few months old, confirm the shipping bolts on the back panel were removed.
- Listen during spin: a loud rumble or metal-on-metal grind, rather than a thump, points at worn shocks or bearings.
Prevent it next time
Most shaking is cured for free by not overloading, balancing bulky items, and keeping the machine dead level, so make a level check part of the routine and lock the feet once set. Our washing machine maintenance checklist includes the leveling and hose-slack checks that prevent a walking machine, and staying on top of the gasket cleaning gives you a regular reason to inspect the feet and hoses at the same time.
When to call a pro
Bring in a pro when a level machine with a balanced load still shakes violently, or when spin brings a loud rumble or grinding that signals worn shocks or bearings. Shock absorbers run $50–200, and a drum-bearing replacement is a labor-heavy $200–400 job. Because a bearing repair on an older machine can approach the price of a new one, our when-to-replace guide is worth a look before committing, especially past the 10-year mark.

How do I level a washing machine?
Set a bubble level on top of the machine and check it both front-to-back and side-to-side. Turn the threaded leveling feet up or down until the bubble centers in both directions and the machine no longer rocks when you press each corner. Then tighten the lock nut on each foot against the cabinet so the setting cannot drift. On an uneven floor, a self-leveling rear foot design or a thin shim under a front foot can finish the job. A truly level machine is the single best defense against shaking.
Why does my brand-new washer shake so much?
Almost always because the shipping bolts are still in. Front-load washers ship with 3 to 4 bolts through the back panel that lock the drum in place for transport, and they must be removed before the first wash. If they are left in, the suspension cannot absorb the spin and the machine shakes hard and bangs. Check the back panel for the bolts and pull them (keep them for any future move). Also confirm the machine is level and the feet are locked.
Is it bad to run a washer that shakes and walks?
Yes, over time. A machine that walks can stretch and rupture its water hoses, yank the drain hose free, and flood the floor, and the constant pounding wears the suspension and bearings faster. It can also damage the machine's cabinet and any pedestal it sits on. None of that is worth ignoring for a fix that is usually free. Stop the cycle, rebalance the load, and level the machine before you run another spin.
What does a loud rumbling on the spin cycle mean?
A deep rumble or grinding that grows louder as the spin speeds up usually means the drum or tub bearings are worn. Unlike a thumping imbalance that you can fix by redistributing the load, bearing noise is constant and comes with a bit of play if you rock the drum by hand. Left alone, failing bearings can eventually seize or let the drum wobble enough to damage the tub. Plan on a bearing replacement, a $200–400 job that leans toward replacing an older machine.
