Low salt will come up after unit has been on for any where between 30 min. to a few hours. Salt level strips are showing where level of salt should be. I have clean the unit per the manual. Why would it work for a while and not keep on working. Order this unit on line a few weeks ago and no invoice came with the unit trying to get one but it is hard to belive that this system went down only after a couple of weeks used. Could I be over looking somethin

Easy fix. These this have really crappy quality control coming from the factory and are not calibrated properly. Mine was reading 91 and I had an OVER salted pool by they time i tested.. (still reading code 91) Anywho.. here is the fix, its pretty easy.. just be sure to unplug it before doing the below.. This fixed mine perfectly.
Hey , the "CODE 91" fix was said a while back regarding resistors. pull off cover carefully, both the flow sensor and cell power cables exit the case making lifting the plastic case difficult but manageable. look for three adjustable resisters, one above the other. They are marked (or mine was) VR1, VR2,and VR3 on the circuit board. they were black and about the diameter of a pencil eraser with a small Philips (+) adjustable head. The head was locked with glue? but it can be scraped off. The original suggestion said to turn the VR1 resister a quarter turn CCW. This did not work for me but I added an additional quarter turn CCW (now half a turn CCW) and it is back working as it did originally. I will keep an eye on my salt content to keep at 3000ppm as suggested in manual.
How long did you filter before trying to generate chlorine also you say salt is at what it should be what is the ppm
