LG Washer Disassembly

1. Remove two screws on the back of the top plate.

2. Pull the top plate backward and lift, as shown.

3. Remove the detergent drawer.

4. Remove two screws behind the detergent drawer.

5. Disconnect the connector for the Display PWB.

6. Remove one screw from the corner of the control panel.

7. Lift the top away from the support rail and pull the control panel up and away to remove.

8. Remove eight screws to separate the control panel and PWB.

9. Reassembly is the reverse of these steps.

Hall Sensor

The Hall Effect sensor is easily removed and replaced.

You’ll have to remove the rotor and stator to access the sensor.

When replacing the rotor, you’ll probably need a helper to hold the drum in place when you push the rotor onto the shaft.

Otherwise, the drum may move forward enough to make replacing the bolt difficult.

The helper can also hold the drum from turning while you tighten the bolt.
