Aquapure PLC1400 pro series. I installed a new VSP and get a general SWG fault when the pump is operating at low speed. Shows a 120 code so i figured it was just low flow. Now I'm getting the same fault at any speed. Its three years old and I cleaned it once but there was really nothing to clean, looked brand new inside. I'll take it apart again to clean, meanwhile any ideas? oh the middle of the three connectors on top looks a little rusty inside the female end, but don't think thats the issue. The pool water is within the pool school recommendation chem levels, and 3000 PPM salt.
