how can i make my hoover 1200 special edition spin properly?

it goes through the motions with everything else but as soon as it starts to spin it struggles. it goes vroom...... vroom..... squeak.... vroom. hahaha. it washes but doesnt spin properly so the clothes are still fairly wet when they come out. i checked for loose wires and there seems to be none.The motoe just can't seem to get into full spin mode.
