Enquiry preparation
Hob: make a short sequence of events
For a hob enquiry: Describe selection, operation and outcome in that order. Add anything that still responds normally, keeping your observation separate from a suggested failed component.
We agree suitable work and arrangements for your actual appliance.
For the appliance you actually own
Identify electric, induction or gas format and which zone changed. For induction, include any normal-use pan-recognition message without deliberately repeating unsafe tests.
How this supports the discussion
The hob reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
Confirm the proposed attendance
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
