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

Safety first: Unplug the cooker before any inspection. Do not attempt live testing unless you are trained and equipped.

• Check outlet and cord: Verify the wall outlet with another appliance. Inspect the Xiaomi power cord and plug for visible damage. Replace the cord if any defects are found.
• Try another outlet: Plug the cooker directly into a different, known-good outlet without an extension cord.
• Internal fuse check (advanced): Remove the bottom cover and locate the input fuse on the PCB. Test it with a multimeter for continuity. Replace only with the same type and rating if blown.
• Inspect PCB: Look for burnt components, cracked solder joints, or bulging capacitors in the power supply area.
• Board replacement: If the fuse blows again immediately or the SMPS section is visibly damaged, replace the main control PCB. Do not bypass the fuse.
• Professional service: High-voltage power supply repair is hazardous; if you are not experienced, have a qualified technician perform the diagnosis and repair.
