Washing Machine *spare or repair -

Spares or repair Hotpoint Aquarius Extra Washing Machine, 1000 Spin WMA 30. Bought 2nd hand a few months ago but belt on back has come off, but bought a new one....just couldnt fit it ourselves as kept slipping off, so unsure if anything else is wrong. Probably a quick and easy job for someone with know how. Will accept sensible offers. Thanks for looking
