Washer-dryer makes loud banging or knocking noises during spin

Safety first: Unplug the appliance before removing panels. Do not continue to run the machine with severe banging; damage can worsen.

Step-by-step checks:

• 1. Check load: Ensure you are not washing single heavy items. Redistribute laundry and try again.
• 2. Verify leveling: Adjust the feet so the machine is stable and does not rock.
• 3. Inspect suspension: Remove the front lower or rear panel. Press down on the drum; it should move smoothly and stop quickly. If it bounces or the shocks feel loose, replace the shock absorbers as a pair.
• 4. Check springs and weights: Inspect top springs and concrete weights for cracks or looseness. Tighten bolts or replace damaged parts.

When to call a technician: If the drum appears off-center or the tub has excessive play, bearing or spider arm failure may be present and requires professional service.
