Washer-dryer vibrates excessively or "walks" across the floor during spin.

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

Step-by-step checks:

• Remove transit bolts: If newly installed, ensure all rear transit bolts and packing have been removed according to the Proline installation guide.
• Level the machine: Adjust the front and rear feet so the cabinet is stable and does not rock. Lock the feet in place.
• Inspect shocks: Remove the rear or front panel and check the shock absorbers for oil leaks or loose mounts. Replace in pairs if worn.
• Check springs: Inspect the top suspension springs for stretching or damage. Replace if necessary.

When to call a technician: If vibration persists after leveling and basic suspension checks, professional diagnosis is advised.
