How to Fix / Troubleshooting

Safety: Disconnect power before accessing internal components.

Verify cookware: Use a flat‑bottomed, ferromagnetic pan (a magnet should stick firmly to the base). Ensure the pan size matches the zone size.
Center the pan: Place the pan centrally on the marked cooking zone. Some Miele zones require full coverage for detection.
Inspect coil connections: Remove the cooktop and access the underside. Check the induction coil wiring and connectors for looseness or burns.
Coil continuity: Measure resistance of the suspect coil; an open circuit indicates a failed coil that must be replaced.
Module check: If the coil is good, the pan detection circuit on the power module may be faulty, requiring module replacement.
