Troubleshooting Guide
Before contacting service, review the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No ice production | No power; water supply off; clogged water filter; high ambient temperature. | Check power connection and circuit breaker; ensure water supply valve is open; replace water filter; ensure unit is in a suitable environment. |
| Low ice production | Clogged water filter; dirty condenser; high ambient or water temperature; restricted airflow. | Replace water filter; clean condenser coils; ensure proper ventilation and operating temperatures. |
| Ice is watery or soft | High water temperature; mineral buildup on evaporator; unit not level. | Ensure water supply is cool; perform a cleaning cycle to remove mineral buildup; level the unit. |
| Unusual noise | Loose components; unit not level; normal operational sounds. | Check for loose parts; ensure unit is level; some operational sounds (e.g., pump whirring) are normal. If noise is excessive or new, contact service. |
| Water leaks | Loose water connections; clogged drain line; damaged components. | Check all water inlet and drain connections for tightness; clear any obstructions in the drain line; contact service if damage is suspected. |
If troubleshooting steps do not resolve the issue, contact a qualified service technician.
