Bertazzoni Rangetops E3-IND Error: Induction module fault
What Does E3-IND Mean? E3-IND is an internal induction module fault on Bertazzoni induction rangetops. It signals that the power control electronics within the affected zone’s induction module — most commonly the IGBT switching component or the communication bus — have experienced a hardware failure. Unlike the transient overvoltage fault E1, E3 does not clear […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. Shut off the affected zones and discontinue use until the induction module is inspected. A persistent E3 indicates a hardware failure that cannot be safely bypassed — continuing to attempt operation may cause additional board damage.
Can I reset the code?
No. E3 from an internal component failure does not clear with a power-cycle reset. A 5-minute breaker off soak is worth a single attempt, but if E3 returns immediately the board requires professional repair or replacement.
When to stop immediately?
Stop if you notice: E3 returns immediately after every power-cycle reset, Burning smell from beneath the cooktop when E3 is active.
Symptoms You May Notice
Induction zone or entire cooktop section is completely unresponsive
The affected zone does not respond to touch or zone selection commands — it may appear dark or display E3 immediately on any activation attempt, with no heating occurring at any power level.
Power cycling does not clear the E3 code
Unlike transient faults, E3 from an internal module failure returns immediately after every power-cycle reset, confirming that a hardware component rather than a software state is the cause.
Entire cooktop section may go dark or become unresponsive
If the failed IGBT supplies multiple zones through a shared power stage, all zones on that side of the cooktop may shut down simultaneously when E3 appears.
Possible Causes
IGBT power inverter component failed on the induction board
The insulated-gate bipolar transistor is the main switching component that converts DC power into the high-frequency AC field the induction coil requires. A failed IGBT disables the entire zone it drives.
Requires ProfessionalInternal communication fault between the induction board and microprocessor
A communication bus failure between the power control stage and the main microprocessor causes the board to report E3 and lock the zone out as a safety measure.
Requires ProfessionalSafe Checks You Can Do
-
1
Perform a 5-minute circuit breaker power-cycle
Switch the dedicated circuit breaker completely off for 5 full minutes to discharge the induction board capacitors entirely, then restore power. If E3 does not return in the first 60 seconds after activating the zone, the fault was transient.
A 5-minute soak is worth attempting even for E3, as induction board firmware can occasionally latch into a fault state that a full capacitor discharge resolves.

Confirm which zones are affected
Test each zone individually after the power-cycle reset and note which zones display E3 and which operate normally. Provide this information to the service technician — it helps identify whether the fault is on the left or right power module.
Do not attempt repeated activation of an E3 zone — continuously trying to start a zone with a failed IGBT can cause additional board damage.
When to Call a Professional
Contact a qualified technician if:
- E3 returns within 60 seconds of activation after every reset attempt
- IGBT or other components on the induction board show visible damage
- Fault affects multiple zones simultaneously
