E09 appears and cooker stops; often associated with power fluctuations or after plugging into a different outlet.

Safety first: Unplug the cooker before inspecting the cord or outlet.

• Check outlet: Plug another appliance (like a lamp) into the same outlet to verify stable power. Avoid using extension cords or power strips with the multicooker.
• Inspect power cord: Examine the Tiger power cord for cuts, kinks, or burn marks. Ensure the plug fits snugly in the outlet and in the cooker socket (if detachable).
• Try a different outlet: Use a properly grounded wall outlet on a different circuit to rule out household wiring issues.
• Reset the unit: Leave the cooker unplugged for 10–15 minutes, then plug back in and attempt a short program.
• Internal fault: If E09 persists on multiple outlets, the internal power supply or surge protection components on the main PCB may be damaged and require board-level repair or replacement.
