Last year our display had no led lights. The display works. It is not reading the salt level. It stays at 0. They said our salt cell was bad. We got a new cell this year and the problem is the same. We had the water tested today and it is about 2800. I was instructed by our pool place to push the diagnostic button 5 times to reset everything. It went through and it registered everything, but the salt level stayed at 0 and still no led lights. Checked the power input and fuse, everything is good there. We don't know if it is generating or not. We just opened it all up so the water test was good. What is happening with this thing? Hayward no longer has a trouble shooting line. I have to call my pool place. They insisted it was the salt cell last year. I spent a fortune on one (I did not purchase it through them) and have the very same issue. Can anyone help me??
