good deal, Ill post this afternoon.Just push the little black button and record all of the readings.
Salt does not go away unless you lose water other than evaporation and then refill with fresh water.
So, the salinity should be about the same as before unless you have lost a lot of water and refilled.
You should get a K-1766 salt test kit and/or a good salinity meter to verify the actual salinity.
Reinstalled OEM board with new display board, here are the diagnostics without any changesI cannot help with a non-OEM Hayward pcb. I can only assume your salt level is way too low for the cell to produce chlorine or perhaps the cell is dying. Hence, the fault condition. How are you measuring your salinity? But anyway, I was about to suggest to re-install the old board for comparison. All you need is a couple of female Spade connectors for the AC power.
Should you decide to use the old board, run the diagnostic 10 secs after the "Generating" LED comes on and post all the readings. You have exactly 50 seconds before the controller error out if it detects any fault condition.
I appreciate yalls input and expertise. The fix was the rectifiers and a new display board. The display board was already having problems before the rectifiers went out. I'm stuck with a new non OEM board, but $300 for new PCB board, display board, and rectifiers beats $1,200 for a new system as recommended by a pool tech after the new non OEM board was popping the 20amp fuse. I guess he didnt think of the rectifiers. None the less, I again appreciate the help.I ordered from Ebay and then saw your post so I ordered a set from digi key. The Ebay ones came first so i installed them
I just encountered a smimlar problem. My F1 20amp fuse not only was blown but melted. The fuse pins are corroded due to high contact resistance. Also, Pins #2 & 4 on the Molex connector are charred. I had to construct a Bypass for them directly to the PCB board underside via a WAGO connector. Thanks for the info and your past troubleshooting efforts. Fortunately the fuses and rectifiers are available on Amazon-2 day delivery!
