SOURCE: Pool Heater with communication (CE) Error

Code "CE" stands for communication error and describes a fault between the mother board and the display. I doubt it's the relay causing it though...

SOURCE: I'm receiving an error code CE on my Hayward H

Open up the control panel access door on the front. (the display). Remove the 2 screws at the top and tilt the assembly out. There should be a tab on the bottom that helps keep the assembly stable. Check all the connections on both boards for fit and broken wires. If all is ok, I would shut the supply power off, then back on and see if the data transfer works. If not, bad boards.

Testimonial: "Great advice. Working like a charm. No loose wiring. 2 large beetles between the circuit board and the display. Blew them out and it works great."

SOURCE: I have a CE error

According to a Hayward manual the CE error code is a communication error. Here is quote, "If communication between the ignition board and the display board is not established
within 3 s of power-up an error will be displayed. After communication is
established, if it is lost for 30 s, the error will be displayed. The error code will
be cleared upon a valid data exchange between boards."

I don't think you can do any harm by turning the power off, opening the cover and drying everything out the best you can. In addition, if you carefully unplug and then replug each of the connectors then that may also help correct a communication error.

I hope this helps and please vote on this answer. Thank you.
