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

Safety first: Verify the wall outlet with another appliance. Unplug the cooker before opening any covers.

• Check outlet and cord: Try a different outlet. Inspect the Tristar power cord for cuts, kinks, or burn marks. If the cord is detachable, ensure it is fully inserted.
• Look for life signs: Some models have a small indicator LED. If nothing lights, suspect internal fuse or PCB.
• Bottom cover inspection (advanced): With the unit unplugged, remove the bottom cover. Locate the small glass or ceramic fuse on the PCB near the mains input. If visibly blown, replace only with the same rating and type.
• Check mains inlet: Ensure the socket where the cord plugs into the cooker is not loose or cracked.

If a new fuse blows immediately or there is no visible fuse, the main control PCB or power supply components are likely faulty. Professional diagnosis is recommended.
