Washer makes loud banging or knocking noises during spin, machine may move or "walk" across the floor.

Safety first: Keep clear of the washer while it is violently shaking. Unplug before inspecting internal components.

Step-by-step:

• Check load: Stop the cycle and redistribute heavy items. Avoid washing single heavy items alone.
• Verify installation: Ensure all shipping bolts have been removed (front-load). Level the washer using a bubble level and adjust feet.
• Inspect suspension: For top-loaders, check suspension rods and springs for wear or detachment. For front-loaders, inspect shock absorbers and tub springs for leaks or breakage.
• Replace worn parts: Replace all suspension rods or shocks as a set for best performance.

When to call a technician: If the tub is contacting the cabinet or if structural parts are damaged, professional service is advised.
