Washer-dryer combo makes loud banging or knocking noises during spin; drum may hit the cabinet.

Safety: Unplug the appliance. Avoid running the machine if it is violently shaking, as this can cause further damage.

• 1. Check load: Open the door and redistribute laundry. Remove heavy items and run a spin again to see if noise improves.
• 2. Inspect shocks: Remove the rear or front panel and locate the shock absorbers attached to the tub and base. If they are oily, loose, or move with little resistance, they should be replaced in pairs.
• 3. Inspect springs and counterweights: Check that the top suspension springs are intact and that concrete or cast-iron counterweights are secure.

Replacing shocks and springs requires cabinet disassembly but is manageable for a skilled DIYer. If the tub has struck and cracked the cabinet or weights, seek professional service.
