Got home this afternoon and tried recommendations with no luck. Decided to pull cover off and kept messing with switch and button. Heard it click on and other lights came on and salt level is now reading correctly!!! Must have been something in the box not making a good connection. So relieved! My salt cell has outlasted all the others that I have seen posted so I thought it had bit the dust. I'm between 6 and 7th year! Yeah me!!!
