The 'cross like thing' Michiel refers to is the spider. If the front of the machine can be removed, do so and remove the front of the outer drum. If not, you will need to either remove the case or take the whole drum out of the case. This will require disconnecting wiring/water pipes so that the drum is isolated from the case. Then remove the front of the outer drum and the inner drum should pull out. This gives you access to the inner bearing. Not a job for the faint hearted. I am not conversant with your particular model, so cannot go into further detail, but basically this is what is require to replace bearings. Sorry I am not more help, but you at least now have some idea of the task you are undertaking. Best of luck.
