I just acid washed my salt cell yesterday and it was working but the check cell light was flashing. Today the Check Salt light is red and the Check Cell light is yellow both on solid lights. My pool does have a lot of calcium in it but I got it down to 390. Does this mean my Salt Cell is dead and need to replace it? The SWG is the CircuPool Si45plus system. I think if I call the company they will tell me it is dead because the warranty was up last year. The salt level is 3200
