Cor pump was cleaned in the last month. No issues in it's history to this point. I got an error while at work (Module error on Cor_3_1 (Volt)). It cleared in 6 minutes and has not returned. I cannot speak for what the pump did immediately before, during, or after the error as I was not there. Right now it shows 100% OK pulling 64 watts, 2814 RPM, & 55% on temp. I did not get a Hi_Sump alarm at any time so if it did shut down it didn't shut down long enough to raise the water level in the sump.
