how do i oil the bearings in my dryer?

My 6 year old Fisher & Paykel Sensor Dryer turns over when i press the button, and turns for a second then stops. i press it again and it turns the opposite direction and stops after a second again. I have been told it is the motor or the Bearings (that the shaft goes in to) just need oiling. I am not sure where these are. This has slowly happened over 6 months, sometimes stopping mid cycle.
