Overheating protection has been triggered. The cooktop heating switches off automatically before it can overheat.
Turn the knob for the affected cooking zones to 0.
Allow the cooking zones to cool down sufficiently before switching them back on.
Check whether the fan is being blocked by objects in a drawer below the cooktop, or by dust or similar substances, and remove the blockage accordingly.
The overheating protection is triggered again even though the cause has been eliminated.
If the fault persists, please contact us or book a repair appointment online.
