Washer-dryer makes very loud banging or knocking noises during spin.

Safety first: Unplug the appliance. Do not continue running the machine if it is violently shaking, as further damage may occur.

Step-by-step checks:

• Check installation: Ensure the machine is level on a solid floor. Adjust the feet so the cabinet does not rock.
• Verify transit bolts: On recently installed Candy combos, confirm that all rear transit bolts and spacers have been removed.
• Inspect dampers: Remove the rear or front lower panel and examine the shock absorbers. If they are oily, bent, or offer little resistance when moved by hand, replace them in pairs.
• Check suspension springs: From the top, inspect the springs holding the tub. Replace any that are stretched or broken.
• Balance loads: Advise users to avoid overloading and to mix large and small items.

When to call a technician: If noise persists after suspension repair, the drum bearings or spider may be failing and require professional replacement.
