“COMMUNICATION ERROR” on a Pro Logic, Aqua Logic or Aqua Rite PRO
The “COMMUNICATION ERROR” message means the main board and the display no longer talk to each other. The cause can be the main board, the display (the keypad) or an accessory plugged into the board. These checks give you a good idea, then we tell you what to send us.
Applies to: Aqua Rite PRO (the rectangular model), Pro Logic, Aqua Logic / Aqua Plus and OnCommand.
1. Does the equipment stop when the error shows?
- Yes, the pump or other equipment stops: the main board is probably the cause.
- No, everything keeps working: isolate the accessories (step 2).
2. Isolate the accessories
- Turn the power off.
- Keep the main display plugged in.
- Unplug everything on the white connectors at the top left of the main board (for example a wireless antenna or a Sense and Dispense).
- Also unplug the green 4-screw connector at the top left, if something is connected to it (another display, a variable-speed pump…).
- Turn the power back on.
- The error is gone: an accessory is the cause. Plug them back one at a time to find which one.
- The error stays: the problem is the main board or the display (the keypad).
3. Contact us before you send anything
Give us the result of these checks and we’ll tell you which part to send. Most of the time, it’s only the main board. The display is expensive to repair: don’t send it unless we ask for it.
Or call us at 438 448-0782.
To remove the board: watch the video. The troubleshooting guide takes you through the same steps.

Once we’ve confirmed the part, we repair original Hayward boards within 1 to 2 business days after we receive them, with a 1-year warranty. By mail (Canada, USA and other countries) or by appointment in Mont-Saint-Hilaire, Quebec.
