CE is a communications error on the board...the control module and/or Display interface assy. probably need to be replaced.

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."

CE error code on our Hayward Pool heater


That means the computer is not talking to the sensors in the unit. Check all the connections, cables etc. Could be a bad board.

How do I fix an error code CE on my unit? We had a big storm overnight, and now the heater won't work.


this indicates a communication error between the heater and control module. it may be as simple as disconnecting the main power to both the heater and control module to reset system. be sure to allow enough time for the system to 'forget'. usually 1 minute is fine.

The code CE is showing on my Hayward pool Heater what does that mean and can I fix it


I have just repaired my H400 series pool heater from the 3rd CE error in only 3 years since the pool and heater were installed. In each case the circuit board (F0059-456600) was in some way to blame .... I will explain.
Case 1 : Only months after installation the CE error came up. Rain water had got in around the display module and water-damaged the circuit board. It was replaced under warranty. Since then I keep a big plastic lid covering the display unit when the heater is not in use.
Case 2 : 1 year from new the CE error came back. On investigation it was found that a rat had managed to get inside the heater (there are big gaps around the pipe entries) - it had then partly chewed through the ribbon cable joining the two circuit boards together. Display circuit board was replaced at my cost - and all was well again. I also rat-proofed the heater - eliminating all the big openings with chicken wire.
Case 3 : Fired up the pool heater for the first time this year and CE came up. I pulled the display module and this time found obvious signs of blackening / burning on the display circuit board under the big green resistor (R1). Luckily I had kept the old circuit board from the previous time and was able to make 1 good board from the two I had - back in action now.
So in my experience it has been the display circuit board each time - and it only takes a phillips-head screwdriver and about 10 minutes to get it out.

CE ERROR


CE is a communication error.

This is an automatic check performed anytime the unit is powered up. If there is no data communication between the main panel and the ignitor you will get this code within 30 seconds.

If communication is re-established this code will disappear.

DO NOT do any of the following with AC power on / to the unit.

First check the ignitor then, the wiring and terminals from the ignitor to the main board.

There just might be a corrosion problem with the circuitry or corrosion on the main board itself.

Thanks for using FixYa.
