Bertazzoni Cooktops E Error: Electronic hardware fault
What Does E Mean on a Bertazzoni Induction Cooktop? The E code on a Bertazzoni induction cooktop signals an internal electronic system fault. The control board has detected a condition — a failed IGBT module, a gate driver fault, or a communication breakdown between the touch interface and the power board — that it cannot […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. An E alarm means the control electronics have detected a hardware fault. Disconnect from power and contact a Bertazzoni authorised service centre — do not use the affected zone.
Can I reset the code?
Yes. A full power-cycle from the breaker clears transient software faults. A persistent E after a 5-minute power-off cycle requires professional diagnosis.
When to stop immediately?
Stop if you notice: E returns immediately after a full 5-minute power cycle, Error appeared after a power surge or nearby lightning strike.
Symptoms You May Notice
One or more induction zones stop heating mid-cook and will not restart after the cooktop is turned off and back on
The control board has detected a hardware fault on the affected zone and disabled it as a protective measure. Other zones may continue to work if their electronics are unaffected.
Letter E remains on the zone display immediately after a power-cycle with no cooking attempted
A persistent E that returns without any cooking load rules out a transient software fault — the underlying hardware requires inspection and likely component replacement.
Possible Causes
Main control board or IGBT module hardware fault
A failed IGBT power module, a blown gate driver, or a processor exception has caused the control board to disable the zone as a safety measure.
Requires ProfessionalDisplay board to main board communication failure
A loose or corroded connector in the ribbon cable harness between the touch display board and the main power board causes a communication fault that the firmware interprets as an electronic system error.
Requires ProfessionalSafe Checks You Can Do

Power-cycle the cooktop from the circuit breaker
Turn off the cooktop at the circuit breaker for at least 5 minutes, then restore power. Observe whether E returns immediately or only after attempting to cook.
A soft reset clears transient microprocessor faults. If E returns immediately without any cooking attempt, the board has a hardware fault that requires professional diagnosis.
When to Call a Professional
Contact a qualified technician if:
- IGBT module gate voltage is absent on oscilloscope test
- Control board shows burned or discoloured components under inspection
- Ribbon cable connectors show corrosion or physical damage
