Welcome to the Forum!

Goldline (now bought by Hayward) makes the Mineral Springs unit and it's identical to all their Aqua-Rite systems, except for the stick on labels.

I'm certified, supposedly- I took and passed the course, but never received any paperwork??? , on these units and the no flow issue has nothing to do with the high salt reading. How old is that puppy?

Call Goldline @ 888-921-7665. Be prepared to wait on the phone for a while and have the serial #s for both the control box and the cell on hand.

While you're waiting, check the gray 'telephone cord' coming off the flow sensor (it plugs into the bottom of the control box) - it might have gotten cut by a weed whacker or the plug is loose (also try wiggling the cord where it goes into the flow sensor and see if the "NO FLOW" light starts blinking - If it does, the unit will start producing in ~ 1 minute)

I hope this is a quick, easy and inexpensive fix for you
