Hi lostboy, the drum should move fairly easily, so it could well be that the belt has come off or snapped jamming the drum as freak_unique says, if you turn the power off take the back off of the machine probably about 8-10 screws holding it on, you will soon see if belt has gone, you may be able to see if you remove top, probably just acouple of screws at back holding that on, normally once you take those screws out the top slides forward and lifts off, make sure you unplug it before attempting any panel removal,good luck, Ray, let us know how you get on.
