I just bought a home with a saltwater pool. Is has an Intellichlor IC40 and is hooked up to a Pentair EasyTouch system. Everything was working fine initially, but now the IC40 is acting strange. The “flow” light is red and the salt level LED’s alternate between good and low, constantly, back and forth. Now sure what the issue here is, and I can’t find any info online. My pool guy thinks the cell is going out. Any help for a first time pool owner is appreciated!
