Asko Cooktop E1 Error: Cooktop overheating
Asko cooktop E1 error is a common issue reported by Asko appliance owners. What Does Asko Cooktop Error Code E1 Mean? Error E1 on an Asko induction cooktop indicates the thermal protection circuit has tripped. Induction electronics generate significant heat during operation, and if the internal temperature sensor detects a value above the safe threshold […]

Answer to continue safely
Is it safe to keep using?
Maybe. After full cooling the cooktop can be used cautiously at lower power levels. Avoid high-power or multi-zone cooking until the root cause of the overheating is identified and fixed.
Can I reset the code?
Yes. E1 clears automatically once the internal temperature drops to a safe level. No manual reset is needed — simply wait for the cooktop to cool.
When to stop immediately?
Stop if you notice: Stop use immediately if you detect a burning plastic smell from under the cooktop — this indicates PCB or wiring damage., Do not continue using the cooktop if E1 returns within a few minutes of restarting on a single zone at medium power..
Symptoms You May Notice
Cooking zone cuts out at high power settings
One or more zones stop heating while set to boost or high power, particularly during prolonged cooking sessions.
E1 displayed on zone or main display
The zone display or central display shows E1 and the affected zone becomes unresponsive to touch controls until the cooktop cools.
Cooktop warm to touch around the surround
The glass ceramic surface around the zone and the stainless trim feel warmer than normal, indicating heat is not being drawn away efficiently.
All zones deactivate simultaneously
In a total thermal shutdown all active cooking zones shut off at once and the cooktop requires a full cool-down before restarting.
Possible Causes
Blocked ventilation
Objects placed against or underneath the cooktop block the airflow path, causing the electronics bay to heat beyond the safe limit.
DIY PossibleFailed internal cooling fan
Asko induction cooktops use a brushless fan to cool the inverter electronics. Once the fan seizes, even moderate cooking rapidly overheats the board.
Requires ProfessionalSustained multi-zone boost use
Running all zones simultaneously on boost power for extended periods can temporarily push internal temperatures above the threshold even with a healthy fan.
DIY PossibleSafe Checks You Can Do
-
1
Cool down and clear ventilation
Switch all zones off and wait at least 20 minutes. Remove any items from directly above or below the cooktop that might restrict airflow. Check the ventilation grille (typically front or left side) and clear any grease build-up with a dry cloth.
The cooktop's minimum installation clearance at the front grille is typically 5 cm — do not push items flush against it.

2
Test with a single zone at medium power
After the cooktop is fully cool, activate one zone only at power level 5 (mid-range). Cook for 10 minutes and observe whether E1 returns. If it does quickly, the cooling fan is likely faulty.
Listen for the internal fan — you should hear a soft hum from within the cooktop during operation. Silence indicates fan failure.

Check installation clearances
Verify the cooktop is installed with the correct underside clearance to the cabinet base as specified in the Asko installation guide (typically 20–30 mm below the cutout). In a built-in installation with a drawer below, confirm the drawer was fitted with the required ventilation gap.
Installing a false bottom panel with ventilation holes in the drawer below the cooktop is the correct fix for under-cooktop airflow problems.
When to Call a Professional
Contact a qualified technician if:
- E1 recurs within 5 minutes of restarting a single zone at medium power after a full cool-down.
- No fan noise is audible during cooktop operation — internal fan has seized.
- Discolouration or heat damage is visible around the underside ventilation grille.
