why is my hayward chlorinator not working

by Dr. Anissa Kiehn Published 3 years ago Updated 2 years ago

Our Hayward system shuts the chlorinator off automatically when the water flow is too low. I can usually hear when the system is struggling for water as the pump gets louder and makes a recognizable sound. Ensure all proper valves are open and weren’t closed, thereby restricting water flow. Check the skimmer for blockages.

An air lock inside the chlorinator can also reduce flow and chlorination. To clear an air lock, remove the lid, then turn on the pump and allow the chlorinator to fill with water. Turn off the pump; replace the lid, and turn the pump back on again.
