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

Safety first: Unplug the cooker before opening. Work only if you are comfortable with mains-voltage appliances.

Step-by-step checks:

• 1. Check outlet: Test the wall socket with another appliance to confirm it has power.
• 2. Inspect power cord: Look for cuts, kinks, or burn marks. Gently wiggle the cord at the plug and cooker end while plugged in (without touching metal parts). If the unit flickers, the cord or internal connector is faulty.
• 3. Internal fuse: Remove the bottom cover and locate the fuse on the main PCB (often near the power input). If it is visibly blown or tests open with a meter, replace with the same type and rating only after checking for shorts.
• 4. Check mains connector: Ensure the cord's internal terminals are firmly attached and not loose or oxidized.
• 5. Board power supply: If the fuse is intact and there is still no power, the low-voltage power supply section of the PCB may have failed and the board will need replacement.

Note: If the fuse blows again immediately after replacement, there is likely a shorted component on the PCB or heater circuit that requires professional diagnosis.
