How to Fix / Troubleshooting
Safety first: Unplug the unit and allow it to cool for at least 30 minutes.
- Clean all filters: Remove and clean pre-motor and exhaust filters as per the manual. Ensure they are completely dry before refitting.
- Clear vents: Vacuum dust from all air intake and exhaust grills.
- Reduce drag: Check that the brush height (if adjustable) is not set too low, causing excessive resistance on thick carpets.
- Inspect motor area: Open the housing and ensure the motor cooling path is not blocked by lint. If the thermal protector trips frequently despite good airflow, the motor or protector may need replacement.
