Possible Causes
Dirty condenser coil, Weak compressor, Low refrigerant charge, Scale buildup on evaporator plate
How to Fix / Troubleshooting
Safety: Unplug the unit before cleaning internal components.
Steps:
- Clean condenser: Remove dust and lint from the condenser coil and ensure the condenser fan is running properly.
- Descale evaporator: Use a manufacturer-approved ice machine cleaner or a diluted vinegar solution. Circulate the cleaner through the water system (following the manual) and allow it to dissolve mineral deposits on the evaporator plate. Rinse thoroughly.
- Check ambient temperature: Ensure the unit is not installed in a very hot room or near ovens or direct sunlight, which can reduce ice quality.
- Monitor cycle time: If ice forms very slowly even after cleaning, the sealed system may be weak or undercharged, requiring professional service.
Note: Regular descaling is essential in hard water areas to maintain ice size and clarity.
