Possible Causes

Supply voltage outside specified range, Internal power supply overload, Shorted component on heater circuit, Faulty surge protection components on PCB

How to Fix / Troubleshooting

Safety first: Disconnect the multicooker from the mains. Do not continue to operate if there is a burning smell or visible smoke.

Step-by-step checks:

  • 1. Verify mains voltage: Ensure you are using the cooker with the correct regional voltage (e.g., 220–240 V for EU models). Avoid using unstable generators or long undersized extension cords.
  • 2. Inspect power cord: Check the Saturn power cord for cuts, kinks, or burn marks. Replace if damaged.
  • 3. Internal inspection (advanced): Remove the bottom cover and inspect the input section of the PCB (near where the cord enters). Look for burnt MOVs (surge suppressors), fuses, or tracks.
  • 4. Check for shorts: Visually inspect heater wiring and connectors for melted insulation or contact with the metal chassis.
  • 5. Test on a different outlet: After inspection, test the cooker on a known-good outlet without other heavy loads.

Recommendation: If E12 persists or any components appear burnt, the main PCB likely needs replacement. Do not attempt to bypass fuses or protective components.
