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

Don’t replace the PCB, when the hall sensor is replaced.

Replace the PCB, when the LE is displayed after replacing the hall sensor.

Press the Power button & Start / Pause button.

Does the Drum stop when the start/pause button is pressed to start the cycle ?

Or Sometimes does the Drum rotate weakly (under 15rpm)?
