Common Reasons For Chlorinator Shutdown
The Hayward Aqua Plus chlorinator may stop working for several reasons. Understanding these common causes helps in fixing the issue quickly. This keeps your pool water clean and safe without long downtime.
Power Supply Issues
The chlorinator needs steady power to work properly. A loose plug or damaged cord can cut off electricity. Circuit breakers or fuses that trip also stop the device. Checking these parts first saves time and effort.
Faulty Control Board
The control board manages the chlorinator’s functions. If it fails, the unit might shut down unexpectedly. Signs include no display or error messages. Replacing the control board usually restores normal operation.
Salt Cell Problems
The salt cell creates chlorine from salt in the water. Dirt, scale, or wear can block its operation. A dirty or worn-out cell reduces chlorine output or stops it. Regular cleaning or replacement keeps the system running well.
