Multicooker does not power on at all; no lights or display when plugged in.

Safety: Unplug the cooker before opening. Mains voltage is present inside; if you are not experienced, seek professional help.

• Check outlet and cord: Test the wall outlet with another appliance. Inspect the power cord for damage and ensure it is fully inserted into the cooker (for detachable cords).
• Inspect internal fuse: Remove the bottom cover and locate the glass or ceramic fuse on the main PCB near the AC input. Test with a multimeter; if blown, replace with the same type and rating only.
• Check AC connector: Ensure the AC inlet socket and its wires are firmly connected to the PCB and not burnt.
• Look for burnt components: If there are obvious burn marks or a burnt smell on the PCB, the board likely needs replacement rather than simple repair.

If a new fuse blows immediately or there is no visible damage but still no power, the main control PCB or power supply components are likely defective and should be replaced by a technician.
