Display shows E12; unit may beep and stop, often associated with very low or very high mains voltage conditions.

Safety first: Disconnect the ice maker before opening any electrical compartments. Work only if you are familiar with mains safety.

• Measure mains voltage: Use a multimeter to check the outlet voltage. Gorenje ice makers typically require stable 220–240 V AC. If voltage is unstable, contact an electrician.
• Inspect plug and cord: Look for heat damage or looseness at the plug. Replace the cord set if necessary.
• Check internal terminal block: Remove the rear cover and inspect the mains terminal block for loose screws or discoloration. Tighten connections securely.
• Examine power supply board: Look for bulging capacitors, burnt components, or cracked solder joints on the low-voltage power supply section of the main PCB.
• Replace power module/PCB: If the supply is confirmed stable but E12 persists and the board shows damage or incorrect output voltages, replace the main control PCB or separate power module as per Gorenje design.
