How to Fix / Troubleshooting
Safety first: Disconnect power at the breaker before any internal inspection.
- Visual inspection: Remove the cooktop from the counter as needed and inspect the induction module for burnt components, cracked boards, or melted connectors.
- Check coils: Test each induction coil for continuity and for shorts to ground using a multimeter. Replace any coil that is open or shorted.
- Module replacement: In most cases, E3 indicates a failed power module. Replace the affected module following Bertazzoni service procedures, ensuring proper heat-sink compound and secure mounting.
- Verify cooling: After replacement, confirm that the cooling fan operates and that airflow is unobstructed.
Warning: Induction modules contain high-voltage components; only qualified personnel should service them.
