EC Series Salt Chlorinator

The EC Series salt chlorinator is an excellent choice for your swimming pool. It is easy to use, intelligent, safe and economical. Its compact design requires minimal installation space and allows for easy maintenance. The controller is installed directly on the salt cell, making the system suitable for small and medium-sized swimming pools.

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	The heat-sink temperature is above the normal operating range. The unit must be removed for inspection.	Check whether error code E6 is also displayed. If E6 is displayed, inspect the temperature sensor and replace it if defective. If E6 is not displayed, inspect the control board for a possible fault.
E2	Pool-water temperature is too high	The standard operating water-temperature range is approximately 1045°C.	Check whether error code E7 is also displayed. If E7 is displayed, inspect the water-temperature sensor and replace it if defective. If E7 is not displayed, check whether the pool-water temperature is within the standard range.
E3	No water inside the salt-cell housing	Adequate water flow through the salt-cell housing is required during normal operation.	Check whether water is present in the circulation system. Check whether the cell housing is completely filled with water or contains trapped air. If the cell housing is full, remove and clean the water-level sensor.
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.
