hoover wdm150 not spinning or emptying?

my hoover washer/dryer model wdm 150 will not spin and doesn't empty the drum. It goes through the cycle ok but just wont spin and the clothes are soaking wet. i have to turn the machine off get the clothes out,wont complete the cycle!!..was spinning ok when the drum was empty and top was off but as soon as i put it through a cycle the initial problrm returned. The machine is about ten years old. I hope you can help me with this as it's for an old lady who stays in my street and cant really afford to go out and buy a new machine.
