Common Automation Problems This Guide Covers
A pool technician should open this document when a Hayward ProLogic or AquaLogic automation system is experiencing operational issues, displaying error codes, or when connected equipment (like chlorinators, heaters, or pumps) is not functioning as expected..
What it helps you resolve
- Chlorinator not producing chlorine or showing low power
- System display is blank or unresponsive
- Communication errors with the CSM or other components
- Heater failing to ignite or operate
- Auxiliary equipment not running as programmed
- High salt or amperage readings causing chlorinator shutdown
When not to use
This document is not intended for initial system installation, routine preventative maintenance (unless prompted by an error), or for general programming instructions when the system is operating without fault.
Fault codes covered
Quick diagnosis
Start by checking for a 'Comm Error' on the display: this points to a wiring or communication issue between the main board and a module. Test communication by disconnecting accessories one at a time. If a chlorinator is involved, verify it has cell power before suspecting the automation board.
Qualified personnel only. Opening electrical panels, control boards, or equipment enclosures involves dangerous voltages and should only be performed by licensed pool or electrical technicians. Unauthorized service may void your manufacturer warranty. If unsure, contact a qualified professional.
