I too am having issues with the low salt indicator coming on and shutting the unit off. I took a water sample to the pool supply store and had it tested and the salt was right on at 3100. I added 25lbs of salt anyway to see if it would make a difference but it didn't. I have been messing with it for over a week. I've cleaned the plates with vinegar and checked all of the connections more than once. I tried hooking the pump and SWG up on different outlets and it did run about 5 minutes longer before the low salt light came on. Tomorrow I will try bypassing the control panel as some of you have to see if it will make it through this summer and buy a better on this winter. Any other ideas?
