Suddenly my autoclear isnt working this year. All the lights are on, and it says low salt. My salt is actually too high. The autoclear isnt producing any chlorine. My local pool people havethrown up their hands, and unfortunatly calllng autoclear yielded nothing other than clean it again, and call us back. Its clean, believe me. When i test it..it has an error code 52...unfortunately polaris said there isnt such a thing. Is there a way to use a volt/ohm meter to measure current at cell? any other ideas? thanks.
