classixx is not a model no, all bosch models called classixx, model no is on inside of door. Will guess your machine and say if you have a pear shaped inspection panel in the rear of the machine then remove this, remove the belt ,look down inside below inspection hole you will see 2 bolts holding the motor in place, remove these, then lean the machine back against a wall get underneath and prise the motor off its 4 pegs.
