CE error code on hayward pool heater

CE error code on Hayward pool heater. CE= Communication Error between Control Module. and Display Interface Assembly

Pump bearings, hook up, CE error...not following your sequence of events here. CE error on a Hayward heater means a problem with the control board communicating with the display board. Generally it means you need a new display/bezel assembly. None of this should have anything to do with a motor repair unless at some point during all this someone grounded out line power and sent a surge thru the system in the process.

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.

The CE error code means Communication Error. This is a loss ov communication between boards. It could be the wiring, it could be no power to one of the boards. There is a possibility that if you have a short circuit in one board that is bad, and you replace the other one, that it could damage the new board too. Do you have your manual? you can download one from www.haywardnet.com

Error code "CE" is "Communication Error" the manual for your heater gives the following description.. "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.
That being said If you replaced the board I would check all your connections closely and look for bent pins, corroded/oxidized connectors, etc. If this still does not help give Hayward a call, they usually give pretty good support. You can reach them at 908-351-5400

CE is a communication error between the display board and the ignition board. If you've had a lot of rain lately it could just be that moisture inside the unit is causing the error rather than a bad board. Take the cover off and blast the inside with a hairdryer for a few minutes, making sure to get the boards and connecting wires. That sometimes clears the 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...

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