What to do if my Smeg SIM571B shows F42 or F43 error?

If your Smeg Cooktop displays error code F42 or F43, it indicates that the sensor has detected a discrepancy between the appliance voltage and the mains supply voltage. To resolve this, disconnect the hob from the mains and check the electrical connection.
