Further trouble-shooting...
We have had hard water for about 1 week. I followed the troubleshooting guide and took venturi apart and cleaned it. I watched it cycle and no water entered the brine tank. Any suggestions? thanks,

Hi! I have a model 3002 which had the same problem. I removed and cleaned all of the parts in the venturi assembly, confirmed water out of that valve, wasn't getting water into the brine tank. The manual suggests clearing the tubing; did that, still problem. I ended up taking apart the tube down at the valve in the the tank (removed it, took it all apart, flushed it, put it back together) and now it works.
I hope that you got your own softener working; just thought I'd post this as a ref. for future ppl looking for help.
