Candy CM1 166 won't spin!?

It only just a year old (typical) and no matter what wash i put it on, it will just stop dead half way through and the stop/pause light just flashes on and off. The door will remain locked and the clothes though washed will be ringing wet! Seems to have lost motivation to spin properly.
I've tried putting it on a different spin but it will go round one way then the other way then it'll just die! wont even fill up so i can see if it's draining ok now.
