Yep. A few days ago it started flashing 10 Max and the orange light stayed on. The LED's only go up to Number 4. The instructions say unplug and wait 2 minutes. No it is still reading like before. It worked perfectly since last April 2014. I had a backup Cell and put that in but it still reads as before. Of course Hayward does not respond by E-mail or Phone. Any suggestions? It has a 3 year warranty, they say.
