Could a failing Main Electronic Control Board cause the KITCHENAID KDTM404KPS to have symptom: Dead No Lights?

The AC-to-DC converter on the main logic board is the primary failure point for total power loss. If the integrated transformer or voltage regulators on the board fail, the UI will not receive the low-voltage DC required to illuminate LEDs or process touch inputs. This results in a 'dead' state even when line voltage is present at the junction box.

Could a failing User Interface (UI) Control Console cause the KITCHENAID KDTM404KPS to have symptom: Dead No Lights?

This model utilizes a top-mounted vent system that can allow moisture to condense on the UI circuitry during the drying cycle. Electrochemical migration or trace corrosion on the UI board can short the power rail or the data bus. A shorted UI board will often prevent the entire system from booting, resulting in no lights or response.

Could a failing Dishwasher Thermal Fuse Kit cause the KITCHENAID KDTM404KPS to have symptom: Dead No Lights?

The thermal fuse is a bimetallic safety device wired in series with the main control. If the internal tub temperature exceeds safety thresholds or if the heating element develops a high-resistance short, the fuse will open to prevent a thermal event. This creates an open circuit that mimics a total loss of household power.
