Error Codes and Troubleshooting
Check the error code displayed on the control panel and follow the recommended troubleshooting procedure.
| Code | Meaning | Possible Cause or Note | Recommended Solution |
|---|---|---|---|
| E1 | Heat-sink temperature is too high |
|
|
| E2 | Pool-water temperature is too high | The standard operating water-temperature range is approximately 1045°C. |
|
| E3 | No water inside the salt-cell housing | Adequate water flow through the salt-cell housing is required during normal operation. |
|
| E4 | Pool salt concentration is too high | The recommended salt concentration is approximately 3,500 PPM. | Test the salt concentration with a suitable salt meter. If the reading is above 3,500 PPM, partially drain the pool and add fresh water. Once the salt level returns to the recommended range, the error code should disappear and normal operation should resume. |
| E5 | Pool salt concentration is too low | The recommended salt concentration is approximately 3,500 PPM. | Test the salt concentration with a suitable salt meter. If the reading is below 3,500 PPM, add the calculated amount of salt to the pool. Once the salt level returns to the recommended range, the error code should disappear and normal operation should resume. |
| E6 | Internal control-board temperature sensor fault | The unit must be removed for inspection. | Check the sensor response. If the sensor does not respond, replace it with a new sensor. |
| E7 | Pool-water temperature sensor fault | The unit must be removed for inspection. | Check the sensor response. If the sensor does not respond, replace it with a new sensor. |
| E8 | Input voltage is too high or too low | The unit must be removed for inspection. | Replace the power-supply unit. |
| E9 | Output current is too high or too low | The unit must be removed for inspection. | Contact an authorised dealer for a detailed inspection and repair. |
| EA | Sensor fault | The unit must be removed for inspection. | Check the sensor response. If the sensor does not respond, replace it with a new sensor. |
| EB | Data-storage IC fault | The unit must be removed for inspection. | Contact an authorised dealer for a detailed inspection and repair. |
| EC | Circuit-detection system fault | The unit must be removed for inspection. | Switch the unit off and then restart it. If error code EC continues to appear and the unit does not operate normally after several restart attempts, contact an authorised dealer for inspection and repair. |
