Not sure what to do next. I have replaced the cell and Pcb recently and now the salt reading goes way down and the "check salt" and "inspect cell" lights come steadon every time the pump goes off. When the pump comes back on, of course no chlorine is being generated until I reset the display. The instant salt reading is within normal ranges (3000-3300), so I just reset and everything seems to work fine until the pump goes off again. Is there some trick I'm missing? Another part to replace? Thanks for any assistance.
