How to Fix / Troubleshooting
Safety first: Unplug the ice maker before entering or exiting service modes.
- Reset to factory defaults: Consult the Brandt service manual for the key sequence to reset configuration parameters. Perform the reset with power restored.
- Exit test mode: If the unit was placed in diagnostic mode, follow the manual to exit and return to normal operation.
- Verify board compatibility: If a control board was recently replaced, confirm that the part number matches the exact model and that any required jumpers or DIP switches are set correctly.
- Board reprogramming or replacement: If E20 persists, the configuration memory may be corrupted. The main PCB may need to be reprogrammed or replaced by an authorized Brandt service center.
