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.
• 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
with the motor. Remove items, reset unit and test with a Rinse/Spin cycle.

Disassemble the Hall Sensor
1) Disassemble the hook of Hall Sensor by (-) driver.
2) Pull up Hall Sensor slowly as shown in picture.
1) Adjust the hole of Hall Sensor to
the hooks of stator as shown in red circle
2) Push down the Hall sensor,
and assemble to the hook securely.
Caution
If you disassemble by force,not following the directions,
the hooks of stator(red circled) might break.
Hence need change of stator assembly.
