Door Latch Assembly
The door latch assembly contains the microswitches that signal the control board that the unit is safely closed. In the GDT645 series, these switches frequently fail or the plastic housing warps, preventing the electrical circuit from completing. Without this 'closed' signal, the dishwasher will remain in standby and refuse to initiate any cycle.

Main Electronic Control Board
This board acts as the 'brain' of the unit. On GE models, it is susceptible to software lockouts or tripped safety relays (CSM) caused by internal heater spikes or power fluctuations. If the board's internal fuse or logic fails, the unit will often appear powered (lights on) but will fail to respond to the 'Start' command.

User Interface (UI) Control Board
Located at the top of the door, the UI board is frequently exposed to rising steam. Corrosion on the ribbon cable or the board components leads to unresponsive buttons or a 'dead' display. If the Start button specifically loses its tactile conductivity or the communication link to the main board is severed, the unit will not start.
