My Hayward H200 won't fire and shows a "CE" error. I've had the heater since 2012 with no major issues. I think I need to replace the communication board(s). Can anyone confirm that's my fix and help me identify the parts I'll need to order?

Thank you :)

Welcome to TFP.

See page 14 in https://hayward-pool-assets.com/assets/documents/pools/pdf/manuals/Manual227.pdf?fromCDN=true

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.

Open the heater up and check that critters have not nested in it and chewed wires.
