I have an autopilot DIG-220 with a SC-48 cell. I have had it close to 5 years. I has worked flawlessly with very minimal issues. Over the past few weeks I keep getting a message saying "Check clean cell". I have inspected the cell. There is no scale build up at all. The pool chemistry is perfect. I have tried rebooting the DIG-220 still same message. I checked the volts and amps. 27V 4.4amps. (Is this ok)The salt is at 3400ppm. Does anyone have any suggestions? Is the cell on its way out. It is close to the end of its life in terms of years of service, but I do not want to by another cell if I am going to get the same message. I figured of the cell was bad it would say so in the message display. Thanks for any information you can provide me.
