Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No steam production | No power, water supply off, control panel issue, clogged steam head. | Check power supply and circuit breaker. Ensure water supply valve is open. Verify control panel connection and settings. Inspect steam head for blockages. |
| Insufficient steam | Generator undersized for room, low water pressure, mineral buildup. | Confirm room size matches generator capacity (240 cubic feet). Check water pressure. The Auto Power Flush system should minimize buildup, but severe cases may require professional descaling. |
| Water leaks | Loose plumbing connections, damaged components. | Inspect all connections and tighten if necessary. If a component is damaged, contact customer support. |
| Unit making unusual noise | Air in water lines, mineral buildup, component malfunction. | Bleed air from water lines. The Auto Power Flush helps with mineral buildup. If noise persists, contact customer support. |
