This morning, the 1-touch display of my Jandy system showed salt reading of 25,000 and AquaPure 1400 not working. But the salt content was measured at 3200 just a few days ago. So I tried to recalibrate the Salinity by following the procedure given in the Jandy manual. However, the Front board does not enter into the Salinity display after the 3 beeps. Instead it shows the Aquapure %. Thus, the Salinity cannot be recalibrated. Please help.
