My hayward pool heater is displaying a CE error code. A pool guy came out and looked at it and found that part of the circuit board was burned out. We replaced the circuit board but are still getting the same error code. Do we need to reset the system or is there something else wrong?

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...

CE= Communication Error between Control Module
and Display Interface Assembly
1. Disconnect and then reconnect power to heater.
2. Check for faulty wiring or connection.
Inspect Display Interface Wiring. Ensure Display Interface Plug is securely attached to Control Module. .

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."

Hi, "IF" code is Ignition Failure error. A number of parts can cause this error.
Now if you are the handy type and know how to use a Multi Meter you can try to diagnose the problem. You must know your limits, these heaters can be very dangorus and working with them should not be take light heartily. Know when to call a qualified person.
That said if you want to go forward follow these steps. 1. Ensure gas supply shutoff valves are open. Ensure that main gas shutoff installed adjacent to heater is open. Ensure that knob on gas valve inside unit is in on position. If OK, proceed to step 2.
2. Check for low gas supply pressure. Ensure inlet gas supply pressure exceeds minimum valve indicated on rating plate. If OK, proceed to step 3.
3. Check for faulty flame sense wiring or connection. Inspect flame sense wiring. Ensure wire harness terminals are securely fastened to flame sense and to control module. If OK, proceed to step 4.
4. Check for faulty gas valve wiring or connection. Inspect gas valve wiring. Ensure wire harness terminals are securely fastened to spade terminals on gas valve. If OK, proceed to step 5.
5. Check for gas valve failure or gas valve relay failure
A. Measure voltage across gas valve during trial for ignition. If 24 vac is present and gas valve does not open, gas valve is defective. Replace gas valve. B. If 24 vac is not present, gas valve relay on control module is defective. Replace control module.
