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

Safety first: Ensure your hands are dry and the outlet is in good condition.

• Check outlet: Plug another appliance (like a lamp) into the same outlet to confirm it has power. Reset any tripped breaker or GFCI.
• Inspect power cord: Examine the All-Clad power cord for cuts, kinks, or burn marks. If damaged, stop using the cooker.
• Try a different outlet: Plug the cooker directly into another known-good outlet without an extension cord.
• Check power switch (if present): Some models have a rear or side power switch; ensure it is in the ON position.

If the unit remains completely dead, an internal fuse or the main control board is likely faulty. These parts are not user-serviceable and should be replaced by a qualified technician.
