KSM213 is the Sony laser assembly, not the drive - so of new use for drive parts.
By FAR the most common cause of this type of fault is a slipping drive belt, preventing the draw either opening or closing fully - after a short while it realises the operation has fails, and cancels it - returning the draw to it's original point.
A (far) lesser likely cause could be the limit switches on the draw mechanism, with one of those not working correctly - but that's relatively rare.
