Possible Causes
Battery unable to supply high current, High resistance connection at battery terminals, Main motor drawing excessive current, Firmware limiting power due to repeated faults
How to Fix / Troubleshooting
Safety: Remove the battery before inspection.
Check battery and contacts:
- Clean the battery terminals and mating contacts on the vacuum with a dry cloth.
- Try a second battery pack if available to see if high power mode returns.
Check for blockages:
- Ensure filters and airways are clean to reduce motor load.
If F3 persists with a known-good battery and clear airflow, the motor or control PCB may be limiting current. Professional diagnosis is recommended.
