Could a failing Water Inlet Valve cause the WHIRLPOOL WDT730PAH to have symptom: Not Filling With Water?

The water inlet valve is an electromechanical solenoid that opens a diaphragm when energized. Failure occurs when the internal electromagnetic coil develops an open circuit or when mineral deposits physically seize the plunger mechanism. This prevents the transition from the drain-out phase to the fill phase of the cycle.

Could a failing Overfill Protection Float Switch cause the WHIRLPOOL WDT730PAH to have symptom: Not Filling With Water?

This switch serves as a safety interrupt in the fill circuit. If the mechanical float is stuck in an elevated position due to food debris or calcium buildup, the switch remains open, which electronically inhibits the inlet valve from receiving power to prevent a potential flood condition.

Could a failing Door Latch Assembly cause the WHIRLPOOL WDT730PAH to have symptom: Not Filling With Water?

The dishwasher's control logic requires a confirmed closed-circuit signal from the door's microswitches before initiating the fill sequence. If the plastic housing of the latch is warped or the internal microswitches have failed, the machine will remain in a standby state, as it perceives the tub is not sealed.
