Possible Causes
Refrigerant leak in sealed system, Severely blocked condenser, Weak compressor, Faulty high/low pressure protection sensor (if equipped)
How to Fix / Troubleshooting
Safety: The sealed refrigeration system contains high-pressure refrigerant. Do not attempt to open or recharge it yourself.
User-level checks:
- Ventilation and cleaning: Ensure the unit has adequate clearance and clean the condenser coil and fan area thoroughly with a soft brush or vacuum.
- Ambient temperature: Confirm the ice maker is used within the recommended room temperature range (typically 10–32°C). Extremely hot rooms can trigger protection errors.
- Listen for compressor: When starting a cycle, listen for the compressor running. If it repeatedly tries to start and clicks off, there may be a serious cooling issue.
- Check for oil stains: Look around the compressor and tubing for oily residue, which can indicate a refrigerant leak.
- Professional service: If E9 persists after cleaning and ensuring proper conditions, contact an authorized OBH Nordica service center. Sealed system repairs require specialized tools and certification.
