LG Washer Not Spinning: Direct Drive Motor, Hall Sensor, and Rotor Fixes

LG washers use a Direct Drive motor system where the motor is mounted directly to the drum - there are no belts, pulleys, or transmission. This means when an LG washer won't spin, the cause is almost always electrical rather than mechanical. The #1 cause is the hall sensor (also called the rotor position sensor) - a small $10-15 part mounted on the stator that tells the control board the rotor's position and speed. When the hall sensor fails, the board cannot properly drive the motor and the washer either won't spin at all or spins erratically. The LE error code (motor locked/overloaded) frequently accompanies spin failure. The #2 cause is the stator winding - if a winding is open or shorted, the motor cannot generate enough torque for spin. The #3 cause is a worn rotor with weak magnets - the permanent magnets in the rotor lose strength over time, reducing motor power. LG's diagnostic mode confirms the fault: hold Spin Speed + Soil Level for 3 seconds, then press Start to run the spin test. If the drum barely moves or vibrates without spinning, the hall sensor or stator is the likely cause.
