The Hayward GLX-PCB-DSP is a genuine OEM display printed circuit board (PCB) for Hayward/Goldline AquaRite and AquaTrol salt chlorine generator control systems.

Installation Notes
- Turn off power to the salt system at the breaker before opening the control box.
- Take a quick photo of wire/connectors before removal to ensure correct reinstallation.

- If the new display does not restore operation, the issue may be in the main PCB or power supply section—diagnose before replacing additional parts.

Maintenance Tips
- Keep the control box sealed and dry; moisture intrusion is one of the most common causes of PCB/display failures.
- Inspect cable routing and strain relief so vibration and heat don’t loosen connectors over time.
- Maintain proper water balance (especially calcium and pH) to reduce scaling that can make the salt system work harder.
- If readings seem off, verify salt and water temperature using reliable testing before adjusting output settings.
