We have the Polaris AutoClear Plus and have been getting a code 91 and very low salt readings. The readings are not correct. We have checked with strips and our salt level is around 3300 but the unit is indicating a 2400 level. We've checked with strips and also had Leslie's check at their store today. We had a fuse problem last year (kept getting a 94 code.)
The hubs changed the fuse and we've been ok until about the last few weeks. I am wondering is anyone has had this problem. We will check the fuse tomorrow, but I am wondering if the unit has just had it. It's about four years old.
Any advice you may offer will be appreciated.
Thanks so much.
