Washer-dryer makes a loud banging or knocking noise during spin, especially with heavy loads.

Safety first: Unplug the appliance before adjusting feet or accessing internal components.

Step-by-step checks:

• 1. Level the machine: Adjust the front and rear feet so the cabinet is stable and does not rock. Use a spirit level if available.
• 2. Check load size: Avoid overloading or washing single heavy items. Mix large and small items to balance the drum.
• 3. Inspect dampers and springs: Remove the rear or front lower panel. Check that the dampers are firmly attached and not leaking oil. Inspect the top suspension springs for stretching or breakage. Replace worn components in pairs.
• 4. Tighten counterweights: Check the bolts securing the concrete weights to the tub. Tighten to manufacturer torque if loose.
