Take a look inside the lower service panel, or under the top and you should find tech notes that will explain the error codes and tell you how to put the machine into a diagnosis mode. The notes will also tell you how to test various components.
Unfortunately with this error code your problem could be in the motor, motor control unit, main control unit or the wiring between all of these. You will need to do the testing that is described in the notes, or you may just have to replace parts one at a time. These models are very difficult to diagnose.
