Motor Locked Error (LE)
[Pre Check]
• Gentle wash cycles, such as Perm Press, Delicates, Hand Wash, and Wool/Silk should only be used for smaller loads.
Because these cycles are more gentle in tumbling and spinning, putting too much in the drum can register an issue

• Don't replace the PCB, when the hall sensor is replaced.
Replace the PCB, when the LE is displayed after replacing the hall sensor.
