My pool company (which I no longer have) let the salt get to low.

I noticed the service light on the aquapure and added salt, cleaned both cells and flow sensors. 1 cell goes into the aquapure and 1 into the aqualink. The aquapure still gives me error codes 172/186 and also flashes 102 which I can't find anything that tells me what that means. The aqualink system shows NO FLOW. This cell was added to the system in December so its 4 months old. I tested the front board and the numbers were 1 off from what it should be. I'm at a loss on determining the problem.

Anyone with ideas would be much appreciated.

Thanks
