Hob · your observations
Tell us what the affected zone displays.
Identify electric, induction or gas format and which zone changed. For induction, include any normal-use pan-recognition message without deliberately repeating unsafe tests.
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.
A sound has changed
Explain whether the sound starts immediately or at a later stage, using words such as buzz, scrape, tap or rattle. Burning, smoke or uncontrolled movement mean stopping use, not making a demonstration.
If the symptom has returned
Mention whether previous work was carried out and what changed afterwards, using dates or documents you actually have. A similar symptom does not necessarily share the same cause.
Where several functions are involved
Separate the affected function from those that still respond. Keep each observation in its own sentence rather than combining them into a component diagnosis.
