How can I fix my fisher and paykel 708 smart drive washing machine?

My fp 708 smart drive will not pump water into it, nor spin. We've had problems with it leaking at the begining of the cycle when it's full and during the spin cycle. Last week I smelled something burning and decided not to use it. However, it attempts now to pump water into it when starting the machine, but it doesnt. Also I advanced it to spin, to see if it would spin and it does not. I can hear the motor on but than it just throws an error and beeps.
Can someone help me? How much would it cost to fix? Could it be just the belt?
