I have the PL7700 pcb. Will this be compatible, the only difference I see is that the 7700 has a blue wire connection and this has black in its place.

Hi Chris, It looks like you have a pre-2016 Crystal Pure Salt System, so you would require this Pre 2016 Crystal Pure PCB Board

I have a crystal pure 3,0 system. the control board has a continuous no flow light. the only time is off is when breaker is off. I have replaced the flow switch no change. the power and gen. and super chlorine lights are on. pump is working good no clogs in line. the system has been operating for two years perfect. HELP

The power to my system stays on for 10 seconds then turns off. I replace the fuse and still nothing. This is definately a power issue. Does it call for a replacement board? Does this board fit for Axrite 280 system?

Hi Christian, This does sound like a bad PCB, this PCB does not work on an Aqua Rite. If you have an AquaRite you will need this Aquarite PCB Board

I have a Goldline Controls pn: 066012C-1 rev c. Can I use the PL7750 as a replacement?
Hi Aaron, No unfortunately the PL7750 will not work on the AquaRite. You will need this GLXPCBRITE AquaRite PCB Board

Hi!!! How do i know if its the back ( GLX-PCB-RITE) board or the top board that is bad?

Hi, 9 times out of 10 it is the main aquarite board I would go through our Aquarite Troubleshooting Guide and this should point you in the right direction.

I have a Purline for 40,000. My salt cell is working properly (I had it tested). The instant salinity reads 0 , but testing from the pool store says the pool salt is 2900. I have tried to recalibrate the salinity, but it won't change. I believe I need a new main board, but I cannot find the part# on the board. It was made 6-13-2017. Will the Crystal Pure Main PCB - PL7750, work?

Hi Carmen, Yes this would be the correct replacement board for the PureLine 40,000 Gallon System.

Greetings! What is the difference between the generic Aquarite main PCB's and the PL7750? Are they interechangeable?

Hello Michael. The aftermarket replacement Main PCB for the Hayward /Gold Line/ Swim Pure Saltwater Chlorine Generating Systems is the PureLine AquaRite Main PCB PL7100. The PureLine Crystal Pure Main PCB PL7750 is NOT compatible with those systems. The PureLine Crystal Pure Main PCB PL7750 is only compatible with the Crystal Pure Salt Systems.

I have the PL 7704 SWG. Is this the correct replacement board for it? My display is constantly flashing and says SHI, when I know i am around 3,000 on salt. When I turn it on, it shows salt at 8600. See pic 1. then it switches to all lights on. Pic 2. I don't think it is generatiing any chlorine.
The cell was just cleaned but this happened before and after cleaning.
Hello Nicolette. The Crystal Pure Main PCB - PL7750 is the correct replacement Main PCB for the Pureline Crystal Pure SWG. The High Salt reading has interrupted chlorine generation. The High Salt and Check Cell error lights combined are typically the result of a defective Cell and not a defective Main PCB. The Main PCB interprets electronic information measured at the cell to determine salt concentration. Attached please find the How to Program a Crystal Pure Salt System Please verify the information contained in Steps 4 & 30. Because the cell has been cleaned, it may need to be replaced.

I just installed this replacement board in my PL7704. It all went very smoothly. I have a few questions. My amps now show a negative number when generating (-6.5). Is this correct? I never noticed it before. Also, there are 2 new screens as I cycle thru the menu. at the end it show 0EEE and --EE. Do these mean anything? thanks

Hello Nicolette. Attached please find the How to Program a Crystal Pure Salt System manual. Please note Step 15 - the photo captures the minus sign (-) in the left margin of the LCD, Cell current - amperage Diagnostic Display selection. This is a normal display reading. Attached please find the Crystal Pure Salt System I/O manual Please note page 9, section- Diagnostic Display. Diagnostic Display selections 9 & 10 are referenced there.
