I have a Intex Sand Filter Pump Combo. Model # eco15110-2. I have had this pump for 1 years. We used it last half of last summer and this summer. We dry stored it over winter. I keep getting code 91, the pump beeps a few mins and then puts itself into sleep mode. It of course doesn't pump or filter when in sleep mode. Code 91 means low salt. I tested salt levels and they are a lil over but definitely not low. I have cleaned the electrode that creates the chlorine in a vinegar solution (it wasn't bad to start with) and still code 91. I have researched that the electrode might need replacing but I have also learned they should last 3-5 years before needing to be replaced. My pool is green, my pump won't pump bc of this code 91 and I don't know what else to do. Any ideas or suggestions?
