E8 error appears and the cooker will not start; sometimes occurs after a power surge.

Safety first: Unplug the cooker before inspecting any internal wiring.

• Power cycle: Disconnect the cooker from mains for at least 10 minutes to allow capacitors to discharge. Plug back in and check if the error clears.
• Try a different socket: Plug the cooker into a known-good outlet without extension leads or adapters to rule out supply issues.
• Inspect control panel connection: If accessible, remove the top or front panel screws and gently check the ribbon cable between the control panel and main PCB. Reseat the connector firmly.
• Look for moisture: Condensation behind the display can cause logic errors. Allow the unit to dry in a warm, dry place for 24 hours and retry.
• When to replace: Persistent E8 usually indicates a failed main control PCB or corrupted firmware. Replacement of the board is required and should be done by a professional familiar with Lakeland multicooker electronics.
