Check that the minimum clearances for installing the cooktop have been adhered to. The minimum clearances are described in the operating and installation instructions. There must be a clearance of at least 1/2" (15 mm) between the bottom edge of the cooktop and the interim shelf or oven.
Once this clearance has been established, you must disconnect the cooktop from the power supply in order to clear the fault message.
If the fault persists, please contact Miele Service or book a repair appointment online.
