All too common of a problem with with the Hayward heater. The expensive display needs to be replaced.

Design Flaw in Hayward Pool Heaters Causing CE Error Codes

I have been a pool owner for about 20 years now. I have a 21' diameter above ground pool. It is heated by a Hayward 250 unit. The unit is the 2nd one we have had over a period of 20 years. I too experienced problems with the control panel on the and ended up replacing it on the first unit. The...

Hi Allen, good to hear from you and hope you and family are all well.

Is this is the display panel? I ordered that part and replaced it and the same error came up...so I took out the new one and let the old one just stay. So, what is the part that needs replacing? Also, I read the thread below, or most of it, and I turned off the power to the heater to see if a reset would help? Poster said for 30 seconds, but I learned that it's more like 30 min's to allow all of the static electricity to leave too. Had a display on a gas dryer malfunction and the manual stated to turn off power for 30 sec's. I did and it still had the error. Called an appliance tech and he said to leave it off for 30 mins bc of static electricity. Did that and when I powered it back on, the error was gone.

I'll post back in 30 and let you know what happens...thanks again

CE error Hayward 250 H series pool heater, natural gas

I have been checking my pool temp for a few week just to see where it was. Today the error CE appeared. Last year 2010, exactly to the day, I had the board replaced for the same problem, service determined it was a bad board. That board was the original for the heater which was installed Oct...

You actually have to replace BOTH boards in the system because if not you will just fry another board.

Here are the parts you will need to replace:

IDXL2DB1930 Display Board and FDXLICB1930 INTGR.CTRL.BRD.KIT FD. The second board comes with a new airflow switch and you MUST use the new one with the new board.

Have you had rain recently?

The keypad looks old and original circa 2010... I will order one at 56 dollars and replace it and let you know. Mike

We had like 4 days of rain and got the CE error. I opened up the keypad and used the blow dryer on the keypad board and walla, the code cleared and the heater started up. So it appears I need to get something else to cover the keypad besides the manufacturers cover, as I could feel the water on the board before using the blow-dryer.

Thank you Allen / I’ll check out the info.
No rain recently but we had TONS in May, June & 1/2 of July. Even if you replace all, is there something you can do to prevent moisture penetration?
