Enquiry preparation
Hob: keep a short fault diary
For a hob enquiry: Record a few ordinary occurrences with the programme and stage. Do not deliberately recreate smoke, tripping, leakage near electricity or uncontrolled movement for a video.
Model and requested work checked before an appointment is agreed.

Apply this to your product
Describe one zone or the whole hob, the control response and any exact warning. For induction, include the pan-related observation from normal use.
Why the detail helps
The hob reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
Before an appointment is agreed
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
