Possible Causes

How to Fix / Troubleshooting
Safety first: Remove the battery before any inspection.
- Check battery fit: Ensure the battery locks firmly into place and does not wobble. Clean contacts with a dry cloth.
- Gently tap test: With the battery installed and vacuum running, gently tap the handle and body (avoid the motor area). If the unit shuts off or C2 appears, there is likely an internal loose connection.
- Inspect external joints: Check where the handheld unit connects to the wand and accessories. Ensure latches are secure and contacts are clean.
- Professional repair: Internal harness or PCB connection issues require disassembly and should be handled by an authorized service center.
