Zanussi FLS1383w Drum/Motor does not turn?

The Motor does not turn and the timer does not advance exept when it has been manually turned to near the end of the program, it will then advance the last stage to end the program. Whilst carrying out the above the drum moved very slightly, but only once during 15min of investigation. Some clicking (presumably from the timer) was also heard once but without any movement of either the motor or the timer.

The brushes are OK, I replaced them approx 1 year ago, commutator also looks OK. Any info on checking motor windings at the terminal block would be appreciated.
