The overheating protection mechanism has been activated. The hob heating switches off automatically before the hob can overheat.
Turn the rotary control 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 hob, 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.
