Include the display
A fully dark panel and a lit panel refusing to heat lead to different checks. State whether the change followed a power interruption or nearby work.
Keep the electrical history
If a protective device operated, do not repeatedly reset it to demonstrate the fault. Give the model and existing installation details so suitable assessment can be arranged.
A useful distinction
If only one side of the hob stops, say so rather than reporting all zones. The physical grouping can be relevant to the model's design, even where the front markings make each zone appear independent.
