I Have a Hayward Salt Chlorinating system T-15 Cell. I cannot get the diagnostic to read the salt. I have cleaned the T-15 cell (its one year old), I know the salt is in the pool - I tested it at 3200-3300 ppm. The Diagnostic keeps saying 0000 on the ppm - I also have zero amps - as you can see by the system readout. What am I missing? Is it possible the wire leaing to the system (not the plug for the T-15) needs to be cleaned or serviced in some way?
Any help would be appreciated!!!
