What to do if my GoWISE USA GW22711 Electric Pressure Cooker displays “E04” as soon as I plug in the power cord?

The “E04” error typically indicates a loose power cord connection. Ensure the exterior power cord is securely plugged into both the cooker and the outlet. If the issue persists, there may be a loose connection of the interior red wire or disconnected pressure switch.
