How to Fix / Troubleshooting
Safety first: Unplug the cleaner and let it cool for at least 30–45 minutes.
- Clean vents: Inspect and clean all air vents around the motor housing and electronics. Use a soft brush or vacuum to remove dust and lint.
- Reduce duty cycle: Avoid running the cleaner continuously for very long periods. Allow short breaks during large cleaning jobs.
- Check for strain: Ensure the brush and suction paths are clear so the motor is not overloaded.
- If F5 occurs frequently: The main motor or PCB temperature sensor may be faulty. A technician should test and, if necessary, replace the main suction motor or control PCB.
