How to Fix / Troubleshooting
Safety: Unplug the unit.
Steps:
- Power reset: Leave the ice maker unplugged for at least 10 minutes, then reconnect to see if the error clears.
- Check supply quality: Ensure the outlet is properly grounded and not subject to frequent brownouts. Use a surge protector if necessary.
- Control replacement: If E18 returns, the main control PCB likely needs replacement. Order the correct Bauknecht control module and transfer any wiring one connector at a time to avoid mistakes.
Firmware updates, if available, should be performed by authorized service personnel.
