7. Troubleshooting
If you encounter issues with your onerbl AC/AC adapter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Water softener does not power on. | Adapter not plugged in correctly. No power from outlet. Adapter or water softener malfunction. | Ensure adapter is securely plugged into both the wall outlet and the water softener. Test the outlet with another device. If possible, test the water softener with a known working compatible adapter. |
| Adapter feels excessively hot. | Poor ventilation. Overload. | Ensure the adapter has adequate airflow and is not covered. Verify the water softener's power requirements do not exceed the adapter's specifications (12V AC, 500mA). Discontinue use if overheating persists. |
| Intermittent power to water softener. | Loose connection. Damaged cable. | Check all connections for tightness. Inspect the cable for any visible damage. Replace the adapter if the cable is damaged. |
If these steps do not resolve the issue, please contact customer support.
