E8 error appears and the unit shuts off or refuses to start, often after a power fluctuation.

Safety first: Unplug the multicooker before inspecting the cord or internal wiring.

• Check outlet: Plug the multicooker into a different known-good outlet, preferably not on a heavily loaded power strip. Avoid extension cords.
• Inspect power cord: Look for cuts, kinks, or burn marks along the cord and at the plug. If damaged, discontinue use immediately.
• Reset after surge: If E8 appeared after a power outage or surge, unplug the unit for 15 minutes to allow the control board to reset, then retry.
• Internal inspection (advanced): If accessible, check that the cord strain relief is intact and that the cord’s internal connections to the control board are tight and not discolored.
• When to call a technician: If E8 persists on a good outlet with an intact cord, the control board’s power supply may be damaged and should be replaced by a professional.
