Pentair IC40 salt light red not scrolling when powers up

Nov 6, 2013

I have an ic40 that shows red for salt level, but the level tests at 4400. Usually when it powers up, it scrolls through the lights until it gets a read but now it just starts at red and remains. The other lights are good and it is producing chlorine. Any suggestions?
 
How old is the unit and when was the last time you pulled it and cleaned it?

It's a about a year and a half old and was cleaned about a year ago.

If cell shows good and it's producing chlorine, I would have thought that wouldn't be the problem.

Could being dirty stop the salt reading while everything else still works?
