Kitchen aid loud dishwasher

Ok. So repair man just left and said we need a whole new motor to get rid of how loud the dishwasher is? The door also needs link kit because it slams to the floor.

My question is. What part is it and does the whole motor need replacing for noise or are their bearings that can be replaced? It seems to work but makes a loud humming noise and we can’t run it until we go to bed.

Also the plastic cover over the buttons is cracking on top of the buttons. Does anyone know where to get just that plastic overlay?

Thanks for your help:confused:
