Could a failing Drain Pump Motor cause the LG WT7300CW to have symptom: Not Draining Water?

The drain pump motor uses a magnetic impeller to create centrifugal force for water evacuation. If the internal windings fail due to heat or if debris (like coins or lint) physically obstructs the impeller, the motor will hum or stall, failing to move water out of the tub. This is a common failure point in LG's top-load architecture where there is no external coin trap.

Could a failing Water Level Pressure Sensor cause the LG WT7300CW to have symptom: Not Draining Water?

This sensor monitors air pressure within a tube connected to the tub to determine water volume. If the sensor fails or the tube is blocked by detergent scum, the control board receives an incorrect 'empty' signal or no signal at all, which prevents the logic sequence from firing the drain pump relay.

Could a failing Drain Hose Assembly cause the LG WT7300CW to have symptom: Not Draining Water?

The drain hose is the final pathway for fluid discharge. Over time, internal buildup of biofilm or small objects can create a restriction that the pump cannot overcome, or the hose can collapse/kink during the vibration of the spin cycle, effectively damming the water path.
