I went ahead and replaced and all seems fine. The salinity did read low salt code 144 but I retested at pool store and it was ok (3200ppm at store, sensor was reading 1700ppm) so I recalibrated according to the troubleshooting manual someone posted. All seems well, we'll see. Thanks for all the advice the sites given me!

Thanks a bunch for the advice!

I read through the whole post on no flow, cell reversing etc. I have a 3 yr old system so I took my water into pool store salinity correct temp seems correct, but I still have intermittent no flow even though I cleaned cell and sensor a week ago. I'm convinced the sensor is bad but as one last thing is it worth recalibrating flow sensor? And how do you do it? Press button on circuit board while system running? For how long? Also noted new sensors have a small circuit board attached while my current plugs directly (cord) into the circuit board, do you need to install the board? Or will plug disconnect and I plug directly into my existing as it is now? Thanks in advance Rob
