Washer Drain Pump Motor
Front-load LG washers must confirm the tub is empty via the pressure switch before ramp-up. If the drain pump is mechanically seized or electrically open, the machine will time out during the drain phase and fail to transition to the spin cycle.

Door Lock Switch Assembly
The control board requires a closed-loop signal from the wax motor or solenoid in the door latch to authorize high-speed rotation. If the contacts are burnt or the latch is mechanically misaligned, the spin cycle is bypassed for safety.

Direct Drive Rotor Position Sensor (Hall Sensor)
This sensor monitors the speed and orientation of the Direct Drive motor. If it fails, the control board cannot verify the drum's RPM or balance, leading to a 'shuddering' motion and a failure to reach high-speed spin, often accompanied by an LE (Locked Editor) error code.
