I have a new Miele G5605 SC Futura Dimension dishwasher. It washes beautifully but it has certain problems which other modern dishwashers may have.
First, when it arrived it turned out not to have sides and Miele doesn't make sides. As my dishwasher is at the end of a counter, I had to buy a side from the manufacturer of my cabinets and have it installed.
Second, the machine needs a rinse aid and will not start without it even for just rinse and hold.
Third, I had heard that there is a problem with water pooling with some new machines because they now air dry. On my model, the door opens automatically at the end of the cycle so there is no pooling. But the door does not open on its own after rinse and hold, so water does pooland there is a bit of a smell unless I remember to open the door.
