Why LG Washer Isn’t Spinning Properly? All Possible Issues

An LG washer in good working condition should spin quietly and without any problems. So, if there’s ever a situation when that spinning doesn’t happen, or if there’s a grinding noise coming from inside, that means there’s something wrong.

Your LG washer is not spinning properly because it has electrical or mechanical issues such as:

• Broken motor or speed sensor wires
• Rotor Position Sensor failed
• Motor rotor assembly is worn out
• Main Control Board failure
• Clogged drain pump or drain filter

In the following sections, we’ll explore each of those reasons to help you understand why it happens and what you can do about it.

What it is: All of the components inside your LG washer are connected to each other with wires.

Besides supplying them with the power they need to function, wires also carry ‘instructions’ from the main control board for each component to work a certain way.

Some parts, like the speed sensor, are connected by single wires. Others, like the motor, might rely on several wires bunched together in what’s often called a wire harness.

All of these wires and wire harnesses must be in good condition, and they must also be connected firmly. Otherwise, the components they serve will not be able to function correctly.

Why it fails: If your LG washer isn’t spinning correctly, there could be a wiring problem.

For example, the motor’s wire harness or the speed sensor wires may have somehow become broken, because of the constant vibration.

Whenever wires of any kind get broken, that means crucial components in your washer aren’t getting the proper power they need to function.

As a result, what might happen in your LG washer is that the motor will only run on two phases, instead of the regular three.

Besides failing to spin properly, you may notice that there’s a grinding noise coming from inside the machine.

How to fix: Generally, you’d have two options in this situation: fix the broken wire or replace it entirely from the control board to the motor.

Either case will involve opening the washer’s panels and gaining access to the electrical system inside. If you’re unsure about doing it yourself, don’t hesitate to call a professional.

Here’s what the repair process will look like. Firstly, the power supply to the washer must be disconnected to prevent injury or electrocution.

Then, a careful inspection of the motor wire harness and speed sensor wires has to be done to look for any breakages.

The two ends of the broken wire need to be spliced together for them to work. You could also buy a brand new motor wire harness and replace the entire bunch, too.

What it is: Your LG washer also relies on something called a speed sensor to function correctly.

As the name suggests, this sensor monitors the speed of the drum as it spins. As that happens, the sensor communicates that information to the main control board, which increases or decreases the speed based on the settings you’ve chosen.

You’ll typically find the speed sensor attached to the motor. To correctly identify and locate the sensor, refer to the user manual or any technical sheet that may have come included with the washer.

Why it fails: When it fails, the machine might show several symptoms. Firstly, the washer drum isn’t spinning as it should and making unusual noises.

Besides that, the machine might also display an LE error code, which tells you that the motor has been locked.

There are several reasons for this. For example, this could happen if the motor has become strained by excessive weight loads inside.

However, it’s also possible that the speed sensor has become faulty and isn’t working correctly.

If that’s the case, it could be sending incorrect information to the washer, making it unable to spin at all.

How to fix: A faulty speed sensor will need to be replaced. As always, be sure to disconnect the power supply to the machine to prevent injury or electrocution.

You’ll gain access to the existing sensor by removing the rear access panel. 

There are several parts you’ll need to get past before you reach the sensor. Start by removing the rotor from the tub.

Remove the screws securing the stator wire retainers and bracket, as well as the grounding screw.
