I have a AquaPure 1400, I was receiving the 172/186 error codes, I needed to clean the filter so this past Friday I cleaned the filter, cleaned the salt cell (which had very little build up) scrubbed the 3 sensor electrodes until shiny. I put it all back together and everything looked good. No error codes. A couple of days go by and now I get the code again. The salt cell is almost exactly 2 years old and the sensor is about the same. How do I know if its the flow sensor or salt cell? How can you test a salt cell?
Thank You! T
