Just had this system installed the first week in June. System ran great up until 2 weeks ago. The cell light is flashing red but the flow light is green. From what the book said it meant it had a bad flow senior. The people who put it in replaced that part, but it's still doing the same thing. I read on how to bypass it, but I feel that's not the answer. Has anyone else had this problem? I know for a fact it's still not generating chlorine so I'm going to call the people I bought it from to come back and do it over again. I feel like for being a month old i shouldn't have this problem.
