I have the same problem on my Bosch SMU3036 dishwasher. I have determined that the problem is likely a failed contact on the on-off selector switch part (it's the module that contains those 4 mechanical buttons). I believe that the main contact is still working and that the failed contact simply connect all components to neutral. The proper fix would be to replace the entire on/off switch 4-button module. A cheap fix would be to have a handy person install a jumper from any brown wire to the neutral wire (white) where the power connects. I believe the only side effect is that you'll never see the orange ON indication when the dishwasher is running. The on/off switch should still work.
If it is just glasses and coffee mugs that it refuses to wash maybe you should stop trying to wash these items in this dishwasher.
Could it have to do with the location where you put them? Maybe the direct water jet has a blind spot there while the reflected dirty water concentrates there. That may have to do with the shape of the vessel. I am just trying to make sense out of this unusual behavior. (I am thinking of some remarkable properties of parabolic and elliptic surfaces.)
Bosch Logixx 8 Vario problem is that the conditioner is still in the drawer after the wash is finished
