Root Cause

ROOT CAUSE

On Bosch hobs: Short circuit inside induction heating coil windings, damaged IGBT driver gate resistor, or collector-emitter breakdown.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Isolate hob from mains. Measure coil winding resistance (~0.3–0.6 Ω, never 0.0 Ω). Test IGBT gate resistors (nominal 10–22 Ω). Replace power inverter board. Turn off all cooking zones, switch off mains circuit breaker for 30 seconds, restore power, hold Key lock for 4 seconds.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Cut electrical mains power. Never measure resistance on energized heating circuits.
!Ensure tub water or heating cavity is completely drained and cool to the touch before dismantling.
!Verify absolute zero voltage using an approved 2-pole voltage detector before touching element terminals.

3. Preliminary Mechanical & Visual Checks

Inspect heating element tube for calcification buildup, bulging, pinholes, or blistering.
Check wiring spade terminals for heat discoloration, burnt insulation, or loose crimps.
On thermal Klixon switches: check for manual red reset buttons and verify spring-loaded snap action.

Frequently Asked Questions: Bosch E8207

FAQ TREE

What does error code E8207 mean on a Bosch appliance?

Bosch error code E8207 indicates: Bosch Serie 6 / Serie 8 FlexInduction & PerfectFry Induction Cooktop: Induction inverter IGBT desaturation fault E8207; power transistor over-current trip triggered within microseconds..

What is the root cause of Bosch error code E8207?

The primary root cause for Bosch code E8207 is: On Bosch hobs: Short circuit inside induction heating coil windings, damaged IGBT driver gate resistor, or collector-emitter breakdown..

How do I fix or resolve Bosch error code E8207?

To resolve error code E8207: Isolate hob from mains. Measure coil winding resistance (~0.3–0.6 Ω, never 0.0 Ω). Test IGBT gate resistors (nominal 10–22 Ω). Replace power inverter board. Turn off all cooking zones, switch off mains circuit breaker for 30 seconds, restore power, hold Key lock for 4 seconds.

Is it safe to clear Bosch error code E8207 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bosch code E8207 persists, the physical component causing On Bosch hobs: Short circuit inside induction heating coil windings, damaged IGBT driver gate resistor, or collector-emitter breakdown. must be inspected or replaced.

How do I test electrical resistance for Bosch code E8207 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test Immersion / Air Heating Element & Klixon Thermostat across Between element terminals (unwired). Insulation to earth casing: >20MΩ (OL). Expected nominal reading is 25Ω–28Ω (230V / 2000W) / <0.5Ω (Safety Klixon closed). Tolerance: Formula R = V²/P (±5%). Any earth leakage reading below 2MΩ will trip the domestic 30mA RCD breaker..

What safety protocol must be followed before servicing Bosch code E8207?

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
