Enquiry preparation
Oven: keep a short fault diary
For a oven 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
Identify the oven cavity and cooking mode used. Tell us about the result on that setting rather than describing every oven problem as an element failure.
Why the detail helps
The oven 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.
