Possible Causes
Corrupted configuration memory, Interrupted firmware update, Faulty main control PCB, Voltage spike during operation
How to Fix / Troubleshooting
Safety first: Turn off the mower and remove it from the charging station.
- Power reset: Turn off the main switch, wait 60 seconds, then turn it back on. This can clear temporary memory errors.
- Factory reset: If accessible, use the menu to perform a factory reset. Note that this will erase schedules and custom settings.
- Check battery and power: Ensure the battery is healthy and fully charged. Unstable voltage can cause memory errors.
- Firmware reload: If AL-KO provides a firmware update tool or app, attempt to reload the firmware following official instructions.
- PCB replacement: If E19 persists after reset and firmware reload, the main control PCB is likely defective and should be replaced by an authorized service center.
