I have codes 171 and 183. Cleaned the cell as well as the flow sensor and still have the service light on and low chlorine level in the pool. Any thoughts before i start replacing parts.
We have tried acid cleaning the cell as well as lightly sanded the sensor. Still not working.
Since our pool has no salt/chlorine we have added a few tabs of sodium tri-chloride chlorine to fight the growing mold (yellow spots just started appearing today). I want to stay on top of this, and not let my pool get gross.
