We have a 12 year old Kenmore 80 series washer that quit in the middle of a cycle last night. It will agitate but it will not spin or drain. About a year ago a repairman told us it would probably give out in 6-12 months because of the age of the belt and that we should just buy a new one. My question is whether the problem we're having us a belt issue and is it worth fixing? Thanks!
