A new motor for a washing machine will cost well over £100 with fitting costs perhaps the same. After 7½ years it might be time to bite the bullet and invest in a new machine. If you are in the UK and have access to a Comet store and order before 13:00 and they have it in stock at their depot they will deliver next day and remove the old machine too.
Good luck...
