Possible Causes
Undersized or overloaded circuit, Loose power cord connection, Faulty internal power supply module, Voltage drops in household wiring
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before inspecting the outlet or wiring.
Steps:
- Dedicated circuit: Ensure the SMEG ice maker is on a dedicated circuit with the correct amperage as specified in the manual. Avoid using extension cords or power strips.
- Check outlet: Inspect the wall outlet for signs of heat damage or looseness. Have an electrician replace it if necessary.
- Inspect power cord: Verify the cord is fully inserted and not damaged. Replace the cord set if any defects are found.
- Measure voltage: Using a multimeter, confirm that the supply voltage at the outlet is within the specified range. If not, consult an electrician.
- Internal PSU: If external power is stable but E18 persists, the internal power supply section of the main PCB may be failing and the board should be replaced.
