What the symptom may mean
Heating differs between zones may involve zone design, pan suitability or control behaviour. An engineer assesses the actual appliance; a symptom alone does not identify a component.
Useful details from ordinary use
Record which pans and zones show the difference. Separate the selected programme or control setting from the result you saw or heard. Keep the exact display message if one appeared.
Find the product, safely
Use the model from an existing manual or an accessible label. Do not lift a fitted hob or reach under electrical connections.
Identify electric, ceramic, induction or gas. A ceramic glass surface alone does not establish the heating technology.
Stop if it becomes unsafe
Do not remove covers, reach into moving parts or continue using an appliance with smoke, sparking, a burning smell, water near electrical parts or repeated tripping. Do not restart it to reproduce the problem.
