How can I fix my Hoover, Six 1200, washer/dryer?

Hi

Our washer/dryer has recently started making a lot of noise when onthe spin cycle. It is a kind of grating noise. I noticed last week that clothes are still very wet when the cycle has finished.
I checked the spin cycle and it doesn't rev up- the drum is rotating slowly all the way through the spin cycle.

Does anyone know what the likely problem is and how I could go about fixing it?

Thankyou very much inadvance for any help you can offer.

Warmest regards

Claire
