Progressive Industries EMS failure
It's the 50 amp portable model, less than two years old. Got weird voltage readings on L1, and an error code of 10. Progressive replaced it very promptly and at no cost. Being curious, one of my friends removed the cover and discovered that it had 2-3 tablespoons of water in it. It is of some concern that the cover had no gasket of any sort. Also, the new one has a clear plastic cover over the receptacle that the older one did not have. He's going to let it dry in the sun for a day and then retest. I doubt that will fix it, but you never know.
