Washing machine repairs

Anyone tried repairing their own washing machine???
My front loading washer/dryer has decided to test my patience
Water goes in, water drains out and it makes all the right noises ie the motor BUT the drum doesn't move. It's not jammed and will turn freely by hand so I'm thinking the belt has either become detached or broken.
My question, before I try dragging the b*****d out and disconnecting it and opening it up, is how easy/difficult is it to get to the belt and if necessary change it???
