Bosch Induction Cooktop: not heating

Possible Causes

Cookware incompatibility or improper positioning

How to Identify: Use a magnet on the cookware bottom; if it is not magnetic, induction will not heat; pan must be centered on zone and of suitable size.

Part: Cookware/cooking zone detection system

Overheating protection engaged or automatic shutdown

How to Identify: Cooktop suddenly stops heating after prolonged high power use; unit may need to cool down before resuming.

Control settings or user input error

How to Identify: Cooktop set at very low power level or wrong zone selected; may see no heat while display is active.

Part: User interface/control panel

Internal power connection or electrical fault

How to Identify: Cooktop powers on but zones never activate even with proper cookware; may coincide with intermittent control response or error codes.

Part: Wiring/connection/sensors
