Enquiry preparation
Hob: explain the event before the changed behaviour
For a hob enquiry: If relevant, mention an interruption, altered setting or recent move. Keep the sequence factual. Something happening earlier does not prove it caused the present symptom or identify a failed part.
We agree suitable work and arrangements for your actual appliance.
For the appliance you actually own
Identify induction, ceramic, solid-plate or gas format, then say whether one zone or the whole hob changed. Transcribe the display. For induction, describe cookware recognition from ordinary use without deliberately repeating electrical trips.
The purpose of this detail
The hob reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
What still needs agreement
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
