Some movement during a spin cycle is normal. A machine that suddenly bangs, walks across the floor, or shakes violently is different.
Stop and check the load
A single heavy item or badly unbalanced load can shake the whole machine. Pause the cycle and redistribute the contents according to the manufacturer's instructions.
Is the machine level?
A washer that isn't sitting firmly can move during high-speed spinning. Check whether all feet are contacting the floor.
Did you just install the washer?
New machines may have shipping hardware that must be removed during installation. Check the instructions for your model.
What if it happens with every load?
Persistent shaking may involve leveling, suspension components, bearings, internal supports, or another mechanical problem.
Don't ignore violent movement
Severe movement can damage hoses, flooring, the appliance itself, and nearby surfaces.
