How to Fix / Troubleshooting
Safety first: Remove the battery immediately if you notice strong vibration or burning smell. Do not continue to run the vacuum.
- 1. Check for external causes: Remove the floorhead and wand, then run the motor unit alone briefly. If vibration persists, the issue is internal to the motor.
- 2. Inspect air inlet: Look into the motor air inlet for foreign objects. Do not insert tools into the motor.
- 3. Do not disassemble the motor: Motor units are sealed and not user-serviceable.
- 4. Professional replacement: Contact Miele service to replace the motor unit. Continued use can cause further damage or safety risks.
