Bertazzoni Cooktops E5 Error: Zone temperature sensor fault
What Does E5 Mean on a Bertazzoni Cooktop? E5 on a Bertazzoni induction cooktop signals a temperature sensor fault on one of the induction zone modules. Each zone has its own NTC thermistor mounted directly on the coil assembly; this sensor feeds real-time temperature data to the main control board so the board can regulate […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. Operating with a faulty temperature sensor risks uncontrolled heating on that zone; the affected zone must remain switched off until repaired.
Can I reset the code?
Yes. A power-cycle can clear a transient glitch, but E5 caused by a genuinely failed sensor will return as soon as the zone is activated.
When to stop immediately?
Stop if you notice: E5 returns on the same zone after every power-cycle., The zone becomes very hot without the display showing a temperature level..
Symptoms You May Notice
One cooking zone will not activate
A specific induction zone on the cooktop refuses to start or cuts out immediately after activation, while adjacent zones continue to operate normally.
E5 displayed on the affected zone indicator
The zone's display segment shows E5, pinpointing the fault to that module's temperature sensing circuit.
Possible Causes
Failed NTC sensor on induction module
The zone-level thermistor mounted on the induction coil module has failed, giving the control board an out-of-range reading it cannot use to regulate power.
Requires ProfessionalBroken sensor wiring
The wire from the coil module sensor to the main control board has broken or disconnected, creating an open circuit the board reads as a sensor fault.
Requires ProfessionalSafe Checks You Can Do
-
1
Power-cycle at the breaker
Switch off the cooktop circuit breaker for 60 seconds, restore power, and test the affected zone with a compatible induction pan. A transient board glitch may clear.
Ensure the pan is flat-bottomed and induction-compatible; an incompatible pan can mimic a sensor fault.
-
2
Test with a different pan
Place a known-good induction pan on the zone and attempt to activate it. If the zone works with a different pan, the original pan's base may be warped, triggering a false sensor reading.
A flat steel or cast iron pan is the most reliable test tool for induction zone faults.
When to Call a Professional
Contact a qualified technician if:
- E5 persists across multiple power-cycles and pan combinations.
- NTC sensor resistance on the affected module is outside specification.
- Wiring from the sensor to the main board is visibly damaged.
