Water Inlet Valve Assembly
The inlet valve contains solenoids that open to allow water flow; if the internal coils fail or the filter screens are heavily restricted by sediment, the unit will not fill. This is the primary failure point when the washer hums but no water enters.

Door Latch Lock Assembly
LG front loaders require a 'Locked' signal from the door latch assembly before energizing the water valves. If the latch cannot confirm the door is secured, the control board will pause the cycle indefinitely without filling to prevent flooding.

Water Level Pressure Sensor
This electronic transducer measures tub pressure to determine water level. If the sensor is faulty or the air tube is blocked, it may send a 'tub full' signal to the main control board, preventing the activation of the water inlet valves.
