How to Fix / Troubleshooting

Safety first: Unplug the multicooker before inspecting the cord or internal wiring.

Check wall outlet: Plug another high-load appliance (like a kettle) into the same outlet to confirm it delivers stable power. Avoid using long or thin extension cords.
Inspect power cord: Examine the Lagostina power cord for cuts, kinks, or burn marks. Replace the cord if damaged.
Verify cord connection inside unit: Remove the bottom cover (unplugged) and check that the cord strain relief is secure and the live/neutral wires are firmly attached to the input terminals or filter board.
Try a different outlet: Move the cooker to another circuit in the home to rule out local wiring issues.
Reset and test: After 10–15 minutes, plug back in and run a low-power program. If E9 recurs, the internal power supply or surge components on the control board may be failing.

Board-level power issues should be handled by a qualified technician due to shock risk.

E9 error appears mid-cooking; cooker stops and may show signs of power fluctuation.
