bosch wff 2000 washer - the main drive motor never starts up in the cycle?

fills, pumps out, belt etc in place.

main drive motor has a 6 pin mutiplug input, all the leads brown. with a tester in place, and putting it through the cycle, only the 3rd one fromthe top ever becomes live.

These 6 brown leads must include pos and neg for different motor speeds in the cycle? Any ideas? anyone have a wiring diagram, so I can test the motor - put live input directly into to correct terminal.

Maybe a brush problem is the most likely, but I;d like tobe able to test first that it really doesn;t respond to live input.

Thanks.
