I have an Aquarite salt system. My display reads 9900 all the time. I’ve checked the board for apparent loose connections, found none. Any help ? It’s a 1.59 board.

What are the diagnostic readings?

How do I get the PCB to go into diagnostic mode? I can only toggle through the general areas on the display board. I've gotten to the AL-5 and tried moving the switch from auto to super and back several times but nothing happens.

If it's stuck on AL-5, I don't know how to fix that.

You can see if Hayward will tell you.

If they won't, you will probably have to replace the circuit board.

How old is the box?
