Rotor Position Sensor (Hall Effect Sensor)
This sensor monitors the orientation and velocity of the permanent magnet rotor relative to the stator windings. In an Inverter Direct Drive system, the control board requires precise timing of the electromagnetic phases; if the sensor fails to provide accurate pulses, the motor will hum or remain stationary to prevent a thermal runaway or 'locked rotor' condition.

Drain Pump Motor Assembly
The washing machine's firmware includes a logic gate that prevents the transition to the spin cycle until the pressure switch confirms the tub is empty. If the drain pump motor's internal impeller has separated from the drive shaft or the motor windings have shorted, the standing water (or a false 'full' signal) will inhibit the high-speed centrifugal sequence.

Washing Machine Door Latch Assembly
The spin cycle is mechanically gated by the door lock's safety interlock. If the internal wax motor or solenoid fails to engage the locking pin, or if the microswitch fails to confirm the door is structurally secured, the main control board will not energize the motor stator as a safety precaution against high-speed door opening.
