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

Safety first: Unplug the cooker before any inspection. Do not attempt live testing unless you are a qualified electrician.

• Check outlet and fuse: Test the wall socket with another appliance. Check and replace the plug fuse (UK models) with the correct rating if blown.
• Inspect power cord: Look for visible damage, cuts, or burn marks. If damaged, the cord must be replaced; do not tape or repair it yourself.
• Try a different socket: Plug the cooker into another known-good outlet without an extension lead.
• Internal checks (advanced): If you are competent and the warranty has expired, remove the base cover and check the internal fuse on the mains filter board and the wiring to the main PCB. Replace only with identical rated fuses.
• When to replace: If the fuse and cord are fine but there is still no power, the mains filter board or main control PCB is likely faulty and should be replaced by a professional.
