SOURCE: the temperature buttons on my hayward 400IDL

You most likely need a new touch pad and they are almost impossible to troubleshoot. If everything else works except "button A" then button A is bad and in this case that means the whole thing is bad. Sorry...

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."

I have a pf error on my hayward 400 fdn 2 yr old heater. also it's wired 240 volt ac


Thank you for posting your question here on Fixya.com.


A 'PF' error code for a Hayward heater is an electrical supply wiring error. This code will display if 120V polarity is reversed, low voltage is detected, or if the ground path is not sufficient. Reset is immediate after error is corrected. If you are feeding it 240 it can mean one of the 120 legs is low or open or the grounding is bad. It could even be an issue with the transformer or the control board but it is far more likely an electrical supply problem. Start with measuring the incoming line voltage with a good meter. You should see 240 line-to-line and 120 line-to-ground on each leg. If the reading is off by 10% or more there is an issue to correct. If not check the ground next.

About fixed dialing
If you enable fixed dialing number (FDN) mode, your device only makes calls to contacts on your FDN list. Your device can dial emergency numbers in FDN mode, even if the numbers are not in the FDN list. If your service provider plan includes SMS, you can also send SMS messages to contacts on your FDN list

so if you have this enabled chances are you have to turn it off.
this is how you turn it on so you should be able to use it as a guide to turn it off.



Turn on fixed dialing
1. In the phone options, click FDN Phone List.
2. Click the trackwheel.
3. Click Enable FDN mode.
4. Type the PIN2 code provided by your service provider.
5. Click the trackwheel.

or if you wanna keep it on and add friends to the fdn



Add contacts to the FDN list
1. In the phone options, click FDN Phone List.
2. Click the trackwheel.
3. Click New.
4. Type the PIN2 code provided by your service provider.
5. Click the trackwheel.
6. Type a name and a phone number.
7. Click the trackwheel.
8. Click Save.

and finally some shortcut keys:
To open the phone, press the Send key.
To end a call, press the End key.
To call a selected contact or phone number, press the Send key. To call a speed dial number, hold the assigned key.
To add an extension to a phone number, press the X key. Type the extension number.
To call your voice mail access number, hold 1.
To type a letter in a number field, hold the Alt key.
