I have an Aqua Pure 1400 system, and not having any luck generating chlorine. The only indicator light on the panel which is on all the time is the green power light. However, the cell reversing light comes on once in a while and stays on. All other lights remain off. In the meantime, the pool water is green (algae). I am constantly shocking it to clear it up, but a couple of days later I am back to a cloudy and green pool. The salt content is up to approximately 3200 ppm and the ph about 7.8 - 8.0. I cleaned the cell with a 4-1 mixture of water to acid and that didn't seem to help. I then open the panel and performed the diagnostic test and came up with the following: 3.0, 74 and 90 instead of the manual specified 2.8, 75 and 91. Are these values close enough to rule out the front panel board? The error (service) codes that I am getting are 172, 174 and 181. From what I have read, it sounds as though the sensor is bad? I ordered a new one today ($179.00), part number R0452500. I believe that this is the newer sensor, slotted, not threaded. At this point, and until the new component arrives, what else could be the cause of no chlorine being generated? Could one of the boards inside also be bad? What do I look for? And are there special precautions to take when starting up initially after replacing the sensor? How would I determine if the cell itself is bad?
Thanks in advance.
