I have a Jandy Aquapure 1400 and it isn't generating chlorine. Last summer the pool temp, Auquapure settings, and salinity disappeared from the PDA. I bought a new sensor and while it did generate chlorine, the info never returned to the PDA. Just recently it quit generating chlorine. Ran through the troubleshooting guide and on the backboard the reading for the the AC voltage between T.P.-A and T.P.-B was 87 volts. The DC millivoltsfrom K to H where the reading should be approximately 120 DC millivolts was 0. The DC readings at the backboard for the cell was also 0. Also 0 at the cell. The frontboard tested normally and it shows power, flow, and that the cell is producing. It also gives salinity, flow, and pool temp. So is my back board toast?
Thanks in advance,
