Hoover Nextra HNWL6136 not spinning. ?

My Hoover Nextra washer/dryer is not spinning after the wash and rinse cycle. It runs the pump to empty the water, successfully, but the drum doesn't start spinning round - even though it did agitate on the wash and rinse. After some minutes the cycle completes with the pump stopping and the door unlocking. Any ideas ? I would love to get sight of a manual for this machine.
