E9 error appears intermittently; cooker may shut off unexpectedly during cooking.

Safety first: Unplug the cooker before handling the power cord or base.

• Check mains outlet: Test the outlet with another high-power appliance (e.g. kettle) to ensure it supplies stable power. Avoid using long extension leads or multi-way adapters.
• Inspect power cord: Examine the Lakeland power cord for cuts, kinks, or burn marks. Ensure the plug pins are clean and not loose.
• Secure cord entry: Gently wiggle the cord where it enters the cooker (while unplugged). If it feels loose, the internal strain relief or connections may be damaged.
• Try a different circuit: Plug the cooker into a different wall socket on another circuit to rule out household wiring issues.
• When to replace: If E9 continues on a known-good supply, the internal power supply section of the main PCB or the mains filter board is likely faulty. These are high-voltage components and should only be replaced by a qualified technician.
