Possible Causes

Undersized extension cord, Loose mains plug, Household voltage sag, Failing internal power supply

Safety first: Unplug the cooker before checking the power source.

Use a proper outlet: Plug the multicooker directly into a wall outlet, avoiding extension leads or multi-way adapters.
Check plug fit: Ensure the plug fits snugly in the socket. Replace damaged sockets or plugs.
Test another outlet: Try a different circuit in the house to rule out wiring issues.
Internal PSU check (advanced): If F9 persists on good power, the internal power supply on the PCB may be failing and the board should be replaced.
