My new chlorinator keeps shutting off and saying High Salt/Amps. I spoke to Hayward and they said the sensor can be +/- 500ppm.
I've tested with Aquachek strips and get 3620 consistently. I can reset the chlorinator and it will be fine for awhile then I recheck and it's off again. Readings are high 7's both pos and neg with around 25 volts. Sometimes it shows 3700ppm then amps go above 8 and it shuts off. Hayward says the SWG is ok and to lower salt level. TFP recommends 3600. Do you think the cell is defective?
