    Post Jandy PLC 1400 System Problem

    I have a in-ground 20,000 gallon pool with Jandy equipment including the PLC 1400 and Aqualink. Yesterday I measured the water salinity at 3500 ppm but my 1-touch displayed 1900 ppm and a message to add salt. The Front Board display showed Salinity of 1900 ppm and the " add salt " LED was lit and it showed error code 144. Since the Front Board shows the wrong Salinity value, my 10-year old Trisensor could be bad. But if this is the correct diagnosis, why did the Front Board not show an error message of 172 or 181 ? I appreciate the help.

    I have the exact same specs as you. 20,000 gallon pool with a PLC 1400 and Aqualink. Was getting code 144 and 1900 ppm even though i tested salinity at 3000 ppm. I replaced the sensor today and everything is working again. Make sure you get the new sensor. I purchased mine from Amazon for $180.
