Multicooker shows E8 and may not respond to button presses or may shut down unexpectedly.

Safety first: Disconnect the cooker from the mains before inspecting the cord or internal components.

• Check wall outlet: Test the outlet with another appliance to confirm stable power. Avoid using long extension cords or power strips with high load.
• Inspect power cord: Examine the Xiaomi power cord for cuts, kinks, or burn marks. Replace the cord if any damage is found.
• Reseat AC connector: If accessible, remove the bottom cover and check the AC input connector on the PCB. Ensure it is firmly seated and not discolored.
• Try a different outlet: Plug the cooker directly into a known-good wall outlet. If E8 persists, the internal power supply may be failing.
• Internal PSU check (advanced): A technician can measure the low-voltage outputs (e.g., 5 V, 12 V) from the SMPS on the control board. Fluctuating or low voltages indicate a failing PSU.
• Replace control board: On most Xiaomi multicookers, the SMPS is integrated into the main PCB. If faulty, the entire control board should be replaced with an original part.
• Do not bypass protection: Never attempt to bypass fuses or safety components to clear E8; this can create fire and shock hazards.
