Asko Cooktop E3 Error: Coil sensor fault
Asko cooktop E3 error is a common issue reported by Asko appliance owners. What Does Asko Cooktop Error Code E3 Mean? E3 indicates that the NTC temperature sensor assigned to an induction zone has failed or is producing an out-of-range signal. Because this sensor is the primary safety device preventing coil overheating, the cooktop disables […]

Answer to continue safely
Is it safe to keep using?
Maybe. Unaffected zones can be used normally. The zone displaying E3 must not be used as it lacks temperature protection. Arrange repair promptly.
Can I reset the code?
Yes. A breaker reset clears the display, but E3 will return when the affected zone is selected if the sensor fault has not been repaired.
When to stop immediately?
Stop if you notice: Stop using the affected zone immediately — cooking without functional temperature protection risks fire., Cease all cooktop use if the glass ceramic surface has a visible crack anywhere near the zone..
Symptoms You May Notice
Specific zone will not activate at all
One induction zone refuses to heat regardless of which pan is used — the zone display shows E3 immediately when that zone is selected.
E3 code on affected zone display
The individual zone display or main panel shows E3 for the affected zone as soon as it is switched on, with no heating attempted.
Zone overheats without cutting off
In a rare inverse failure where the sensor reads falsely low, the zone may overheat without the thermal protection activating — a dangerous scenario requiring immediate power-off.
Error appears on cold cooktop at startup
E3 displays the moment the cooktop is powered on before any zone is selected, indicating the sensor is already reading an impossible value before cooking begins.
Possible Causes
Failed NTC coil sensor
The thermistor bonded to the underside of the glass ceramic surface at the zone position has short-circuited, open-circuited, or drifted outside its calibration range.
Requires ProfessionalDamaged sensor wiring
The thin wires running from the sensor to the PCB can be damaged by vibration, heat stress, or accidental impact to the cooktop surface causing the ceramic to flex.
Requires ProfessionalPCB input circuit fault
The analogue input section of the main PCB that reads the sensor signal has failed, producing an incorrect reading even if the sensor itself is undamaged.
Requires ProfessionalSafe Checks You Can Do
-
1
Power-cycle the cooktop
Switch off the circuit breaker supplying the cooktop for 5 minutes, then restore power. Observe whether E3 appears immediately on startup or only when the affected zone is selected.
A transient E3 that clears after a single reset may be caused by a loose connector rather than a fully failed sensor — monitor for recurrence.
-
2
Identify which zone is affected
Test each zone individually. Activate one zone at a time at power level 5 with a confirmed-compatible pan. Note whether E3 is isolated to one zone or appears on multiple zones — this information is critical for the technician.
Document the exact zone position (e.g., front left, rear right) when reporting the fault.

3
Inspect for glass ceramic damage
Carefully inspect the surface of the affected zone for cracks, chips, or impact marks. A cracked glass ceramic surface can damage the sensor beneath it. Do not use a cracked cooktop surface under any circumstances.
Even a hairline crack in the glass ceramic is a safety hazard — the glass can fail under thermal stress during cooking.
When to Call a Professional
Contact a qualified technician if:
- E3 persists on the same zone after multiple power resets — sensor or wiring replacement required.
- Any visible crack or chip in the glass ceramic surface near the affected zone.
- E3 appears on multiple zones simultaneously, suggesting a PCB rather than sensor fault.
