Possible Causes

How to Fix / Troubleshooting
Safety first: Disconnect power before accessing the control board.
- Verify model configuration: Check the rating plate on the Asko ice maker and confirm the control board part number matches the model.
- Inspect jumpers/dip switches: Some boards use jumpers or dip switches to set options. Compare their positions to the service documentation and correct if necessary.
- Check sensor compatibility: If a thermistor or level sensor was recently replaced, ensure it is the correct Asko part number for your model.
- Reset control: After corrections, perform a factory reset or configuration procedure as described in the service manual. If E20 persists, the control board may need replacement.
