How to Fix / Troubleshooting
Safety first: Turn OFF the main switch and disconnect the mower from the charging station.
- Power cycle: Turn the main switch OFF for at least 60 seconds, then ON again. Place the mower on the station and allow it to boot fully.
- Check for software update procedure: Consult the user manual or McCulloch support to see if your model supports a user-performed firmware reset or update via service tool.
- Inspect PCB for visible damage: If you open the mower, look for burnt components, corrosion, or water marks on the main PCB. Do not attempt component-level repair without proper tools.
- Do not bypass safety circuits: If E14 persists, the main PCB must be replaced as a complete unit by an authorized service center to ensure correct programming and safety compliance.
