Thanks Pool Clown for sharing your wealth of knowledge with this as well as other forum communities. I too have the model 1400 old 2 port style approx. 6 years old. Has been regularly maintained and working flawlessly. However it recently too has been intermittently showing "no flow". After covering all the basics I've read (IE. cleaning cell and filters, comparing salt and temp readings manually and through the sensor, cleaning the sensor and powering down the whole system) I decided it was the sensor especially since it was the old white epoxy type and the epoxy was starting to separate from the sensor surfaces. The new sensor does have the black epoxy but different in the fact that it came with a small electronic board at the end of the wire harness (new style I guess?). After following the install instructions everything went back to normal. Except that after a week of running it I noticed it was having trouble keeping up the CL level so I bumped it to 100%, still having trouble, so I bumped up the run time an hour, still having trouble, finally came home the other day to "no flow" again which seems to continue to be and intermittent issue thus my trouble keeping up the CL level. So after all this explanation, would you think this might be a front or back board issue or possibly a bad new sensor? If it is a board issue after this many years should I just upgrade the whole system? Again, thanks for your time and expertise.
