I have a Pool Pilot DIG-220 - it has worked flawlessly for the last couple of years and maintained a good chlorine level. Suddenly it's quit generating any chlorine and the check cell LED is flashing. Mineral level is about 33500-4000. Power is level 1 - which I don't seem able to change. If I try in the installer menu, I see the purifier status and then switch straight to the Check Cell flashing red light.

When this first happened, I checked the cell and cleaned it with diluted muriatic acid - no change. Also cleaned the filter and suddenly it all started working again just for one day and now I'm back to the Check Cell flashing red.

To me, this doesn't seem like declining performance with age but more like something has suddenly died. We have had a flock of bad storms lately.

Does anyone have ideas of where I go from here?
