I called Autopilot regarding a persistent Error "Clean/Check Cell" and it looks like after 2 years my SC-36 cell has failed. The system tests states "Cell=31V, 3.7A", so the tech at Autopilot indicated that the power supply is OK but that the cell has likely failed. I am thinking on doing this myself and ordering the cell and replacement cable online. Found a website "eSeasonGear" with apparently the best prices. I checked the Autopilot website for the authorized dealers list and they do appear there. Does anyone have any experience with this company? Also, my old cell appears to still be making enough chlorine, can I continue to use it until it completely fails (low chlorine levels), or by using it do I risk damaging the rest of the equipment?
