how can i fix my hotpoint aquarius washer condenser dryer?

i have a hotpoint aquarius 1100 washer condenser dryer. every thing works as normal exept the drum won't turn i've had the back off to examine the belt and it is intact. i turned the power back on to the appliance and it started spinning but stopped shortly after. this happened e few times turning the power on and off. could this have been a defective relay resetting by the pull of gravity causing the motor to quickly burn out. i will attempt to repair it myself so would be greatfull for names and numbers of parts you have in mind please thankyou.
