I have a PoolPilot with an RC-42 cell and constant problems. Two years ago I replaced the cell, this year I replaced the sensors, I've had low voltage warnings, shorting problems in the rain and now I'm not generating chlorine again. My salt level is 3700ppm and I have no warning lights but getting no chlorine. So far this year I've gotten one day of trouble free use. Is it common for these to be a constant source of irritation and a giant money pit? I'm thinking of scrapping the whole thing and going back to adding chemicals. At least then I was in control rather than having a computer telling me to spend money.
