Hello ... I have a pool in the CA desert. The Aqua Rite motherboard was replaced in August 2016 and the T-15 salt cell was replaced in May 2019. I did my routine check today of the salt cell due to the LED light was flashing. The cell was clean and I reset the motherboard to stop the flashing light. However, the "low salt" LED and the "inspect cell" are now both flashing, even after the reset. Does this sound like the motherboard is faulty, the salt cell, or what? Thank you for any help you can provide.
