A warning after an empty pan, obstructed ventilation or unusually heavy use gives different context from one appearing immediately on a cold hob.
What the observation means
It does not identify the failed part. The appliance may be protecting itself, and repeated resets can obscure the event.
A useful next step
Stop cooking and follow the manual's cooling instructions. Record the pan, active zones and message. Do not pour cold water over the surface, block a sensor or raise an installation limit to suppress the warning. Persistent or unexplained warnings need assessment before further reliance.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
