Hob · Focused observation
One zone gives a different response
Retain the warning and whether it involves the whole hob or one zone. With induction, note normal-use cookware behaviour. Repeated testing after electrical trips is not an appropriate investigation.
We agree suitable work and arrangements for your actual appliance.

How this relates to your hob
Identify electric, induction or gas format and which zone changed. For induction, include any normal-use pan-recognition message without deliberately repeating unsafe tests.
Describe the observation before its possible cause
Describe what you saw during ordinary use, then retain the complete model. An observation can help frame an assessment but does not establish which part is faulty.
Leave unsafe behaviour undemonstrated
Do not repeat a cycle to recreate smoke, tripping, burning, unsafe movement or leakage near electrical parts. Keep connected equipment in place and do not remove covers.
