An “E1” message is something to do with the sensor cable. The sensor cable is the short skinny cable that runs from the generator to the tower. Please make sure that it’s connected, secondly unplug it and switch the ends around, so plug “A” side into “B” and the “B” side into “A” sometime that makes a better connection. Also make sure that is nothing blocking that connection ie: loose chips, dust. Then check the connection; by wiggling one side of the connection and then the other, if the “E1” message temporally goes away while you were wiggling one side, you need a new sensor connector.
