Einleitung

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.

    • 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

    • 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.

    • 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.

    • 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.

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

    • 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.

    • 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.

    • 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.

Abschluss

To reassemble your device, follow these instructions in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.
