Many hobs detect pan removal and pause or alter output, but the exact timing and resumption behaviour are model specific.
What the observation means
The pan and glass can remain hot after detection stops. Setting the pan down in another position may change which zone recognises it.
A useful next step
Follow the manual and confirm the displayed selection when returning cookware. Do not use pan removal as a substitute for switching the zone off after cooking. If power resumes unexpectedly or the display becomes unreliable, stop use and record the sequence.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
