Is the resistance of the Hall Sensor 5~15kΩ?

[Pre Check]
• Gentle wash cycles, such as Delicate and Wool, should be used only for light 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.

Is the Connector connected correctly to 
the Main PCB and the Motor?
Is the Harness right?

Disassemble the Rotor.
Is the Magnet of rotor cracked or broken?

: 5 ~ 15 kΩ

: 5 ~ 15 kΩ

Replace the Main PCB.

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)?

Is the resistance the same
between Stator points?

V~U / U~W / W~V : 8~11Ω

Reconnect or repair the Connector.

Or replace the Harness.

Replace the Rotor.

Replace the Hall Sensor.

Disassemble 

hall sensor carefully. 

Replace the Stator.
