I just changed my pool to salt water. Every week I am having to clean the cell due to light flashing. The no flow light also comes on frequently. The man that changed it over to salt told me to prime the pool. So I have had to do that several times to get the no flow light off. Now the inspect cell and low salt light is staying on. It will not generate. Even after I added salt, the numbers continue to drop. Any suggestions :?:
