Possible Causes

Worn suction motor bearings, Foreign object in fan housing, Damaged brush roller bearings, Cracked fan impeller

How to Fix / Troubleshooting

Safety: Unplug immediately if abnormal noises occur to prevent further damage.

  • Isolate source: Run the Zanussi cleaner briefly without the brush engaged (if possible). If noise persists, it is likely the suction motor; if it stops, the brush area is suspect.
  • Inspect brush area: Remove the bottom plate and brush bar. Check for stones, screws, or debris caught in the housing. Spin the brush by hand; replace if rough or noisy.
  • Check motor fan: Access the motor housing and inspect the fan impeller for cracks or foreign objects. Remove debris carefully.
  • Replace motor if needed: If the motor bearings are noisy or there is excessive play in the shaft, replace the suction motor assembly.
