Main Power Control Board
The main control board manages the conversion of high-voltage AC into low-voltage DC required for the dishwasher's logic and display. A failure in the onboard transformer or power-switching IC will prevent the unit from powering on or responding to any inputs. This board is the most frequent cause of a completely unresponsive state in this model series.

Noise Filter Assembly
This component is the first stage of the electrical system where the power cord connects to the internal harness. It is designed to filter electromagnetic interference but often fails open-circuit due to thermal stress or voltage spikes. If this component fails, all electrical current is blocked from reaching the main control modules, resulting in a 'dead' unit.

User Interface (UI) Board
The UI board houses the display LEDs and tactile buttons that initiate the machine's operation. If the microprocessor on this board fails or if there is a short in the communication ribbon cable, the dishwasher will appear dead even if the main control board is providing power. It is a secondary suspect if the main PCB and filter are verified functional.
