Thin, cloudy or small ice from a Sub-Zero clear-ice maker is usually caused by mineral scale on the evaporator or water distributor, weak water flow from a failing pump, low water supply, a dirty condenser, or a refrigeration problem.
Clear-ice makers are supposed to produce hard, clear cubes. Changes in quality signal a problem.
Check These First (5 Minutes, No Tools)
- Run a cleaning cycle with approved ice machine cleaner.
- Check the water filter and supply pressure.
- Clean the condenser behind the toe-kick.
- Check the room temperature around the unit.
Most Common Causes
| Cause | What happens | Fix |
|---|---|---|
| Scale buildup | Water doesn't flow evenly over the plate. | DIY / Pro |
| Water pump | Weak circulation. | Pro |
| Low water supply | Not enough water per cycle. | DIY |
| Dirty condenser | Slower freezing. | DIY |
| Refrigeration | Low capacity or sensor fault. | Pro |
How We Fix It
We descale, test the pump and sensors, check thickness settings and verify refrigeration performance.
