Possible Causes
Loose battery latch causing brief disconnects, Cracked solder joints on main PCB, Loose internal wiring harness connector, Worn battery contacts
How to Fix / Troubleshooting
Safety first: Remove the battery before inspection.
- Check battery fit: Insert the battery and gently wiggle it. If the vacuum powers off with slight movement, the latch or contacts are loose.
- Inspect latch mechanism: Ensure the battery latch clicks firmly. If broken, replace the battery latch assembly or handle housing.
- Clean contacts: Wipe battery and handle contacts with a dry cloth.
- Test while moving: With the battery installed, run the vacuum and gently move it. If it cuts out, internal connections or PCB joints are suspect and require professional repair.
