Just added 9 bags of salt to my 14,000 gallon pool. I go to the IC40 and it has red no flow light on and the light for salt is flashing back and forth between OK (green) and LOW (red). My PB is on vacation so not sure what is going on. I have the pool pump running at 75gpm to ensure good circulation and water is clearly going thru the IC40. Does it take some time or some reset for it to acknowledge flow, etc?
