How to Fix / Troubleshooting
Safety: Remove the battery.
Inspect mechanical fit:
- Check that the battery clicks firmly into place and does not wobble.
- Inspect the latch mechanism for wear or damage.
Clean contacts:
- Wipe battery and vacuum contacts with a dry cloth.
Reinstall the battery and test while gently moving the handle. If the vacuum cuts out, the connector or internal wiring is likely faulty and requires service center repair.
