6. Troubleshooting
This section provides solutions to common issues. For problems not listed here, contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water / Unit not turning on | No power, gas supply off, insufficient water flow, remote off. | Check power connection, ensure gas valve is open, verify water pressure/flow, turn on remote. |
| Water not hot enough | Temperature set too low, high incoming water temperature, multiple fixtures running. | Increase set temperature, reduce hot water demand, check for mineral buildup. |
| Error code on remote | Indicates a specific system fault (e.g., flame failure, overheating). | Refer to the detailed error code list in the full manual. Often requires power cycling the unit or professional service. |
| Water temperature fluctuates | Inconsistent water flow, mineral buildup, external factors (e.g., cold weather). | Ensure stable water pressure, consider flushing the unit, verify anti-freeze protection is active in cold weather. |
| Unit leaks water | Loose connections, damaged components, freezing damage. | Tighten connections, inspect for visible damage. If freezing is suspected, contact a professional. |
