Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Ice maker not working / Power indicator off | No power supply | Check if the unit is plugged in correctly. Check the circuit breaker. |
| "ADD WATER" indicator on | Water reservoir is empty or low | Add potable water to the reservoir up to the MAX fill line. |
| "ICE FULL" indicator on | Ice basket is full | Remove ice from the basket. |
| Ice cubes are too small or not forming | Ambient temperature too high; Water temperature too high; Insufficient water | Ensure the unit is in a cool environment. Use cold water. Check water level. |
| Ice melts quickly in the basket | This is a common characteristic of countertop ice makers, which are not freezers. | Transfer ice to a freezer or insulated container immediately after production. |
