Troubleshooting
If you encounter issues with your water heater, refer to the following common troubleshooting tips. For complex problems, contact customer support or a qualified technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water | No gas supply, power outage, low water flow, unit error code. | Check gas valve, ensure power, verify water pressure, check display for error codes and consult manual. |
| Water not hot enough | Temperature setting too low, excessive water flow, cold inlet water. | Increase temperature setting, reduce water flow, allow unit to adjust. |
| Unit cycles on/off frequently | Low water flow, air in lines, short hot water demand. | Ensure adequate water flow, bleed air from lines, this can be normal for very short demands. |
