Fisher & Paykel Cooktops E3 Error: Surface overheat fault
Fisher & Paykel cooktop error code E3 is a high-severity fault meaning Glass-ceramic surface over-temperature (overheat protection). If E3 was caused by empty cookware or an undersized pan, the cooktop is safe to use once cooled and the cookware issue is corrected.

Answer to continue safely
Is it safe to keep using?
Maybe. If E3 was caused by empty cookware or an undersized pan, the cooktop is safe to use once cooled and the cookware issue is corrected. If E3 recurs with correct cookware at low power, do not continue using the zone — a faulty sensor cannot reliably prevent dangerous surface temperatures.
Can I reset the code?
Yes. E3 resets automatically once the glass-ceramic surface cools below the sensor threshold. No manual reset procedure is required. If E3 returns repeatedly with correct cookware, the sensor requires professional replacement.
When to stop immediately?
Stop if you notice: E3 triggers at low power with correct, filled cookware, Surface shows any cracking, discolouration, or burn marks.
Symptoms You May Notice
E3 and zone cuts out mid-cook
The zone switches off without warning during cooking and displays E3; the H (hot surface) indicator remains lit.
Cookware boils dry triggering fault
Empty or nearly empty cookware overheats the glass-ceramic surface, causing the overheat sensor to trip.
Zone will not restart immediately
Attempting to restart the zone returns E3 until the surface cools below the sensor threshold.
Possible Causes
Empty or nearly empty cookware
Pan boiled dry or placed on zone without food or liquid, allowing the base temperature to rise unchecked to the glass-ceramic limit.
DIY PossibleCookware base too small for zone
Using a pan significantly smaller than the zone diameter concentrates heat, causing localised hot spots that exceed the sensor threshold.
DIY PossibleFaulty glass temperature sensor
The NTC sensor bonded beneath the glass-ceramic surface has drifted out of calibration or failed, reporting false over-temperature readings.
Requires ProfessionalSensor adhesive failure
The thermal adhesive bonding the sensor to the underside of the glass has dried out, creating an air gap that delays heat transfer and causes inaccurate readings.
Requires ProfessionalSafe Checks You Can Do
-
1
Allow surface to cool completely
Remove cookware and allow the glass-ceramic surface to cool until the H indicator extinguishes before attempting to restart the zone.
The H (hot surface) indicator on Fisher & Paykel cooktops stays lit until the surface drops below approximately 60°C — do not touch the surface while it is displayed.
-
2
Check cookware suitability
Ensure the pan base diameter matches the zone size and that the pan contains sufficient food or liquid before switching the zone on.
For induction zones, cookware must also be ferrous (magnetic). Non-ferrous pans may still trigger overheat codes on radiant zones if the base is too small.
-
3
Test at lower power levels
After cooling, restart the zone at power level 3 or 4 with a pan of water. If E3 triggers again at low power with a correctly sized pan, the temperature sensor is likely faulty.
Recurring E3 at low power settings with correct cookware is a reliable indicator of sensor failure.
When to Call a Professional
Contact a qualified technician if:
- Glass temperature sensor replacement requires accessing the underside of the cooktop
- Sensor adhesive re-bonding requires the correct thermal compound and curing procedure
- Any glass-ceramic surface crack requires professional assessment before use
