Main Control Board Assembly
The main PCB manages power conversion from 120VAC to the 5V/12V DC required for the display. A failure in the board's internal power regulation circuit (SMPS) or a blown onboard fuse results in a total loss of user interface illumination and machine responsiveness. This is the most common resolution for a 'no lights' condition where house power is confirmed.

Noise Filter Assembly
This component is the first point of entry for electrical power into the dishwasher. It contains an internal fuse and suppression capacitors to filter electromagnetic interference; if the filter fails due to a power surge or thermal stress, the electrical path to the main board is severed, causing a total 'dead' state.

User Interface Display Board
Located inside the door panel, the UI board is susceptible to moisture ingress from steam escaping the tub. Corrosion on the board or its ribbon cable connectors can short out the communication lines or the LED driver circuits, preventing the display from lighting up even if the main PCB is functional.
