Whats up everyone. I am still having issues with my brand new VSP communicating with my aquaplus. I previously had a 3202VSPND for 8 years with no issue. Got the VSP Comm Error this year and pool company diagnosed the pump as bad. I replaced pump with Tristar VS900. I am getting the same error so I dont know if the main board is having issues. I have replaced the communication line just to be safe. Is the Board a common failure on the aquaplus? I tested the voltage on A to Com and B to Com - both showing a little more than a 1 volt. Any other ways to diagnose board? Anyone know what voltage should be? I dont want to spend the money if I dont have to... based on the error still happening I am getting my original pump didnt fail. Any ideas for me to try?
