Use this guide to replace the rotor position sensor in your LG front load washing machine. The rotor position sensor is a Hall effect sensor that detects the primary motor's position, direction, and speed. This guide will work for most LG front load washing machines. This guide is written with a model WM3050CW washer. If you have a different model, you may encounter some minor disassembly differences, but the overall repair process will be the same.

Сначала выполнить:Do these first:

🧰 Tools

Phillips #2 Screwdriver
Socket Wrench
17mm Socket (3/8in Drive)
10mm Socket

ШагиSteps

Step 1

Before you begin your repair, perform the following:
Turn off the main water supply
Unplug your washer
Disconnect all water connections at the rear of your washer

Unfasten the top panel

Remove the screw(s) securing the top panel brackets to the back panel.
You don't need to remove the screws securing the brackets to the top panel.

Remove the top panel

Slide the top panel towards the rear of the device to disconnect its clips.

Step 4

Tilt the top panel upward to completely disconnect it from the chassis.
Remove the top panel.

Unfasten the rotor

Use an impact driver to remove the 17 mm nut securing the rotor.
Alternatively, you can use a wrench and a hammer to loosen the nut.
To secure the rotor, you can insert a screwdriver, or a similar tool, between the rotor and the stator. Make sure to brace the tool against one of the screw bosses on the stator.

Remove the rotor

The rotor is magnetically attracted to the stator.
Pull the rotor straight off the stator and drive shaft splines to remove it.
Wiggle the rotor as you pull to help disconnect it.
This may require significant force.
During reassembly, watch your fingers when aligning the rotor over the stator, as the rotor gets sucked in easily.

Unfasten the motor harness clamps

Remove the screw(s) securing the motor harness clamps.

Unfasten the stator

Hold the stator up as you unfasten the last few bolts, as it can fall over unexpectedly.
Remove the bolt(s) securing the stator.
During reassembly, refasten the screws in a "star" pattern.

Reposition the stator

Don't pull the stator too far away from the device, as it's still connected by wires.
Pull the stator off of the drum and flip it so its rear is facing upward.
Note the position of the stator before continuing, as you will need it face the proper direction during reassembly.

Disconnect the rotor position sensor

Pull the rotor position sensor connector straight out of its socket to disconnect it.

Remove the rotor position sensor

Use your fingers to unclip the rotor position sensor from the stator.
Pull the sensor away from the stator to completely unclip it.
Remove the rotor position sensor.

To reassemble your device, follow these instructions in reverse order. Take your e-waste to an R2 or e-Stewards certified recycler. Repair didn’t go as planned? Ask our Answers community for help.
