Possible Causes
Insufficient ventilation under cooktop, Blocked cooling fan intake or exhaust, Failed cooling fan, Prolonged high-power operation on multiple zones
How to Fix / Troubleshooting
Safety first: Turn off the cooktop and allow it to cool for at least 30 minutes.
- Clear ventilation: Remove any items stored in the cabinet under the cooktop that may block airflow. Ensure vents are not covered.
- Check fan operation: After cooling, turn on a zone and listen for the cooling fan. If the fan does not run, access it from below and check for obstructions or seized bearings. Replace if defective.
- Verify installation: Compare the installation to the Asko manual to ensure required clearances and cutout dimensions are met.
- Usage adjustment: Avoid running all zones at maximum power for extended periods if E3 occurs only under extreme load.
Persistent E3 with proper ventilation usually indicates a failing cooling fan or temperature sensor.
