Could a failing Water Inlet Valve Assembly cause the SAMSUNG WA50R5400AW/US to have symptom: Wont Fill?

This assembly contains multiple solenoids that control the flow of hot and cold water; the internal electromagnetic coils are prone to open-circuit failure due to thermal stress. When the coil fails, it can no longer generate the magnetic field required to lift the plunger and open the rubber diaphragm. This results in a complete lack of water ingress despite the control board providing the necessary signal.

Could a failing Water Level Pressure Sensor cause the SAMSUNG WA50R5400AW/US to have symptom: Wont Fill?

This sensor converts air pressure from the tub into a frequency signal for the main PCB. If the internal transducer fails or the diaphragm becomes brittle, it may send a high-frequency signal that erroneously indicates a 'full' state. The machine logic then prohibits the fill cycle from starting to prevent a theoretical overflow event.

Could a failing Water Inlet Mesh Filters cause the SAMSUNG WA50R5400AW/US to have symptom: Wont Fill?

These fine-mesh screens are situated at the hose connection points of the inlet valve to protect the internal diaphragms from sediment. Over time, calcium carbonate buildup or pipe scale can completely occlude the mesh, creating a mechanical barrier that prevents water from entering the machine regardless of solenoid actuation.
