Hi all, I was having an issue with my salt cell sensor giving me erroneous salt readings and eventually not detecting flow. After looking at troubleshooting guides I decided to purchase a new sensor. I installed it and it worked great for 10 days, reading the salt accurately and detecting flow. All of a sudden, it stopped working and is it is detecting salt readings above 12000 PPM while giving me error codes 172 and 186. Any thoughts on this? Why would a sensor that was working perfectly fine and was brand new, pool company all of a sudden stop working ?
