A Miele dishwasher that does not recognize the selected program can be difficult to diagnose because the appliance may still appear to be functioning normally. The display can turn on, buttons may respond intermittently, and the dishwasher may even begin part of a cycle before stopping. However, when the machine repeatedly fails to register the selected wash program, the problem may involve the control panel, electronic module, or communication between these components.
Modern Miele dishwashers rely on several electronic systems to process user commands and control the wash cycle. The control panel receives the selection, while the electronic module interprets that command and activates the appropriate components. A fault in either system can prevent the dishwasher from starting the intended program correctly.
