The Miele cooktop FE31 error indicates a power supply fault. This issue occurs when the electrical supply to the appliance is interrupted or irregular. Please check that the incoming power supply cable is properly connected to the unit and consult the installation manual for assistance.

Symptom: The cooktop control switches off, followed by a beep that sounds for 3 seconds every 30 seconds, and an “FE31” error code flashes on the display.

Possible causes:

• Live (phase) conductor L 2 not available.
• Neutral conductor N for right power electronic not available (bridge fault between terminals 4 and 5).
• An electronic fault has occurred.

Solution:

• Check the supply connection.
• Ensure the bridge is properly installed between terminals 4 and 5 and has a good connection.
• Check the power electronic (side where FE is displayed) and replace it if necessary. Check the filter/control electronic (2N1) and replace it if necessary.
