The Hayward AquaLogic Main PCB (GLX-PCB-MAIN) is the OEM replacement main circuit board for Hayward Goldline AquaLogic pool and spa control systems, compatible with all date codes including systems operating EcoStar variable speed pumps.
IMPORTANT: QUALIFIED TECHNICIAN INSTALLATION REQUIRED
Electrical control components must be installed or replaced by a qualified electrician or certified pool technician. This PCB is connected to mains voltage (120V/240V) inside the power center. Do not attempt replacement without proper certification and without isolating power to the equipment.
The main PCB is the central control board of the AquaLogic power center, governing the logic and relay switching for all connected pool and spa functions including pump operation, sanitization, and auxiliary loads. Replacing a failed or non-responsive main PCB restores full system control without replacing the entire power center.

Poolaroo Pro Tip
Before ordering, confirm your system is an AquaLogic not a ProLogic by checking the label on your power center and the local display panel. ProLogic systems require a different board. If you are uncertain which system you have, consult your equipment’s installation manual or contact Hayward technical support before purchasing. A certified pool technician can confirm the correct replacement PCB for your specific unit.
