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

Safety first: Verify the wall outlet with another appliance before assuming the cooker is faulty. Unplug before any inspection.

• Check outlet and plug: Test a different outlet. Inspect the plug and cord for cuts, burns, or kinks.
• Try a different socket: Avoid extension leads; plug directly into a wall socket.
• Inspect underside: If accessible, check for a resettable thermal cut-out or fuse (most Tefal multicookers use non-resettable fuses inside).
• Internal fuse: If you are experienced, open the base and check the input fuse on the power PCB. Replace only with the same rating and type.
• If fuse blows again: There is likely a shorted component (heater, triac, or transformer). The main PCB or heater assembly may need replacement by a technician.
