Hi im a poolman in the L.A area i have a customer that has a RC42 Autopilot salt cell its maybe about 2 yrs old since autopilot tech replaced old one including control power box which was about 5yrs old. i noticed cell is giving out 1.6 amps with 32v at module i wash out cell twice and its still giving me 1.7amps meaning cell is not producing chlorine. i called autopilot and there saying cell might be depleted and warranty doesnt cover depleted cells want to know if maybe you know what might of caused depletion and why so soon? I tested water salt is at 3700ppm,stabilizer at 80 ,ph 7.5. i tested hardness and its pretty hi at around 700 she also turns heater on almost everyday on spa mode.
