E12 is displayed and the cooker stops mid-cycle, often when switching from heating to keep-warm.

Safety first: Unplug the cooker before any inspection.

• Check outlet: Plug the multicooker into a different wall outlet on a dedicated circuit. Avoid using extension cords or power strips.
• Monitor other appliances: If lights dim or other appliances reset when the cooker runs, there may be a household wiring issue that needs an electrician.
• Inspect power cord: Check the Electrolux power cord for cuts, kinks, or burn marks. Replace if damaged.
• Internal inspection (advanced): Remove the bottom cover and verify that the mains input connector and strain relief are secure. Look for burnt components in the power supply section of the PCB.
• If E12 persists on a known-good outlet, the internal power supply circuit on the main PCB is likely failing and the board should be replaced.
