Miele KF 364 iD MOUNTED Refrigerator Freezer. I need to make a correct adjustment of the fridge temperature,so that to avoid weak cooling. It works fine, but occasionally water drops appear along the wall at the back, but not on the side walls. There is a console with buttons at the top front of it but I do not remember how to use them.Is the "1-5" button the one for the fridge temperature adjustment?
