Diagnosis
The 'ADD WATER' alert on your Antarctic Star HZB-12B persists even after filling because the unit's water level sensor isn't detecting sufficient water. This can happen if the water level is slightly below the internal sensor probe, if there's an airlock in the water line, or if the water pump itself is momentarily blocked or needs a reset.
How to Fix It
First, ensure the unit is properly filled and reset. Follow these steps:
- Press the ON/OFF button to turn the ice maker off.
- Open the lid and verify the water level is exactly at or just above the MAX line on the water tank. Do not overfill.
- Close the lid securely and press the ON/OFF button to restart the unit.
- After restart, the compressor needs time to stabilize. Wait at least 3-5 minutes before expecting ice production to begin. You should hear the water pump cycle and water flowing.
If That Didn't Work
If the alert remains, try these solutions:
- Check for Air Locks: Tilt the unit slightly (with it off) to help any trapped air in the pump or supply tube escape.
- Inspect the Water Inlet: Ensure the water inlet screen or tube inside the tank isn't blocked by mineral deposits or debris.
- Manual Reset: Unplug the ice maker for 2 minutes, then plug it back in and restart. This can clear a temporary electronic fault.
- Water Quality: Using heavily mineralized water can cause scaling that impedes the pump or sensor. Use distilled or filtered water.
Heads Up
Always use the unit on a level surface. An unlevel ice maker can cause inaccurate water level readings. Never add water while the unit is running, as this can damage the pump or cause improper cycling.
