Bosch Induction Cooktop: coil failure

Professional Repair Guide

What is this symptom?

Experiencing Bosch Induction Cooktop coil failure? You may notice that a specific cooking zone stops heating or works intermittently, even with the right cookware. Other zones may function normally, while error codes or pan detection issues arise, signaling potential internal damage, faulty sensors, or control board failures.

Urgency: Medium

Important Tips for Bosch Models

  • Bosch official materials list generic error and safety codes but do not provide specific coil failure diagnostics; internal failures generally require service support. (

Possible Causes

Internal induction coil damage or electrical failure

How to Identify: Zone will not heat at all even with correct induction‑compatible cookware; may show error codes or shut off automatically; other zones may still function.

Part: Induction coil / induction power module

Faulty pan detection circuit or sensor

How to Identify: Cooktop attempts to heat but display shows pan symbol, flashes power level then shuts off despite correct cookware. (

Part: Pan detection circuitry / sensor

Control board or power electronics failure affecting specific zone

How to Identify: Multiple zones malfunction, erratic behavior or error codes not linked to cookware; inconsistent zone responses.

Part: Control board / zone power module
