How to Fix / Troubleshooting
Safety first: Unplug the ice maker before opening the control compartment.
- Power reset: Leave the unit unplugged for at least 5 minutes to allow capacitors to discharge, then reconnect power and check if E13 clears.
- Access control board: Remove the control panel cover to expose the main control PCB.
- Inspect connections: Gently press on all multi‑pin connectors to ensure they are fully seated. Look for signs of moisture, corrosion, or burnt components.
- Check for damage: If you see burnt tracks, swollen capacitors, or melted plastic, the board is likely defective.
- Replace PCB: If E13 persists after reseating connectors and a power reset, replace the Gram main control PCB. This is best done by a qualified technician to avoid ESD and wiring errors.
