This type of dishwasher is made to be integrated in a kitchen with other cabinets (i.e. covered with the same door material as your other cabinets).

So the entire front of the dishwasher is customizable and can't have any buttons/indicators.

There are plenty of kitchen appliances that have a front panel but still let you customize the rest of the front face to match the cabinets.
