I had the Pentair iChlor30 installed the beginning of August 2021 after a lightening strike killed my old one. Then we closed our pool Oct 1 so it was open for approximately 8 weeks. When I opened it this spring(May), the "low salt" light was on even though the salt level is perfect. When I ran the diagnostic on the salt cell it thinks my salt level is 2,981 and the temperature is 119 degrees. Neither is true obviously. The salt is 4000 and the temp at the time was 70. I called Pentair to do a warranty claim but in order to do that, they needed a full "pool store computer test". I said I haven't had that done in 8 years since I do all my water chemistry work myself. They said they can't replace it unless they have one(I'm sure it's because they are so accurate). So for the first time in 8 years I had the pool store run the tests. Everything appeared fine to me believe it or not. The numbers came pretty close to my testing. BUT, the pool store showed .1 of copper. Pentair said they can't replace it until I fix the .1 of copper. Am I missing something here? That doesn't sem like very much to me. I need to get it fixed in order for them top replace the part so is there a way to get the .1 of copper out without messing everything else up? My latest test FC 4.5, CC 0, PH 7.9, CH 125, CYA 50, Salt 4000, Temp 76 degrees. Feeling furstrated.
