Washer shaking or walking during spin? Check the load, level, and floor

A single heavy item, overloaded drum, unstable floor, uneven feet, nearby contact, or shipping hardware can cause severe vibration—but repeated banging may signal an internal suspension fault.

Short answer: Pause the washer if it is shaking hard, banging, or moving across the floor. Wait for the drum to stop before opening the door or lid, then redistribute a tangled or one-sided load and remove items if the drum is tightly packed. With the washer off and the floor dry, confirm that nothing touches the cabinet and gently check whether the machine rocks at its corners. Follow the exact model’s instructions for leveling and for confirming removal of shipping hardware after a recent installation or move. Run one supervised test only after correcting a visible cause. If the washer still walks, strikes the cabinet, leaks, smells hot, or makes grinding or metal-on-metal noise, leave it off and arrange service.

Why it matters

Whirlpool identifies unbalanced or overloaded loads, installed shipping bolts, uneven leveling feet, and an unstable floor as common causes of a washer that vibrates or walks. Samsung likewise advises checking load size and distribution, the selected cycle, stable floor clearance, firm contact at every foot, and front-load shipping bolts. LG notes that single or bulky items, shipping materials, and poor leveling can create excessive vibration and recommends professional service when vibration remains after those checks. A washer that moves can strain its hoses, cord, cabinet, and internal suspension, so repeated severe vibration should not be ignored or masked with pads alone.

Safe checks, step by step

1
Pause or stop the cycle from a dry, safely reachable control. Keep clear of the moving washer and do not brace it with your body. Wait until the drum is completely still before opening the door or lid. If the appliance is leaking, sparking, smoking, smelling hot, or pulling on a hose or cord, leave it off and follow the stop-and-call guidance below.
2
Check the load after the drum stops. Untangle sheets, redistribute items evenly, and remove some laundry if it is tightly packed. A single blanket, bath mat, pillow, pair of jeans, or other water-heavy item can gather on one side; follow the manual’s bulky-item and load-size instructions rather than adding arbitrary weight. Never reach into a moving drum.
3
Confirm that the chosen cycle matches the load and consider a lower spin speed only when the model instructions recommend it for bulky or imbalance-prone items. Record any imbalance code and when the shaking begins. Do not repeatedly restart a cycle that cannot balance itself or force the door or lid open.
4
With the washer off and the floor dry, look for a hose, cord, shelf, wall, dryer, drain pan, or stored item touching the cabinet and rattling with it. Without pulling or tilting the washer, press gently on opposite top corners. All supported feet should contact a solid floor and the cabinet should not rock. Follow the owner’s installation instructions for any accessible leveling adjustment; keep feet short and locknuts secured as specified.
5
If the washer is new or was recently moved, check the installation paperwork and the exact model manual for shipping bolts, spacers, blocks, or other packing material. Front-load shipping bolts are not operating parts and must be removed as directed, but locations and quantities vary. Do not climb behind, tip, lift, or pull out the washer; have the installer or a technician handle hardware that is not safely visible and accessible.
6
After correcting one clear cause, run one short, supervised test with a modest, balanced load using the manufacturer’s recommended cycle. Stay nearby and stop it if severe shaking returns. Do not use anti-vibration pads to conceal rocking, an unstable floor, loose feet, installed shipping hardware, or a suspected suspension, bearing, tub, or counterweight fault.

Stop and call a professional if

The washer walks, jumps, strikes a wall or cabinet, cannot stay in place, or continues severe shaking after one properly balanced test
You hear grinding, scraping, metal-on-metal contact, repeated heavy banging, or a new loud sound that continues with a normal balanced load
There is water on the floor, a stretched, kinked, bulging, or leaking hose, a damaged cord or plug, sparking, smoke, a burning odor, or a hot outlet
The drum appears off-center, sagging, loose, or able to strike the cabinet; the door, lid, glass, tub, pedestal, drain pan, or cabinet is damaged
The floor flexes, slopes, is wet or damaged, the washer is stacked or on an unstable pedestal, or safe correction requires structural work or moving the appliance
Diagnosis or correction would require opening a panel, reaching underneath or behind the washer, tilting or lifting it, handling internal suspension or counterweights, testing energized parts, or bypassing a lid, door, balance, vibration, or other safety device
