Is there anywhere on the net to find what the error codes mean? I cannot find it in my manual. I am getting this fault "CCM J3 5V" ID: E-0039-04 shorted to low source I was shelling corn and the low chopper speed alarm went off. I checked and everything mechanical looked fine then about 2 minutes later the screen said self leveling sieve not level and that error came up. The sieve angle displays --- and it is completely turned to one side.
