LG washers are known to be one of the most reliable electronics on the market, however, they do not come without their own set of flaws. An LG washer not spinning problem is not usually a reason for cases and with the fixes we have listed below, you should get the washer spinning again.
LG Washer Not Spinning: Likely Causes & DIY Fixes
1. Broken Motor Wire Harness Or Speed Sensor Wires
All components inside the LG washer are connected to each other with wires. These wires not only supply the components with the power they need to function, but also carry instructions from the main control board for each component to function properly.
Some components, like the speed sensor, are connected by single wires. Others, like the motor could be connected by several wires which is often called a wire harness. For the washer to spin and function properly, all of the wires must be in good condition. This is not a very common problem if you’ve been taking proper care of your washer, but it could be the reason why it fails to spin.
Solution: Check for Broken Wires
Broken wires can cause problems like constant vibration and cut off power to essential parts of the washer. To solve this problem, you can either fix the broken wire or replace it. Either option will require opening the washer’s panels and gaining access to the electrical system inside. First, you need to confirm that there are broken wires, so you might want to call a professional.
This process will require knowledge of the washing machine’s wiring so you might want to check other fixes and only take this as the last option.
2. Rotor Position Sensor Failed
The LG washer relies on a speed sensor to function correctly. The speed sensor monitors the speed of the drum as it spins. Through the settings on the main control board, the speed sensor will increase or decrease the speed of the drum.
A speed sensor failure could be why your washer refuses to spin. You can easily tell it is a speed sensor failure when the washer isn’t spinning as it should and making unusual noises. In some cases, the machine will display an LE error code that tells you that the motor has been locked. However, this could also be due to adding excessive load to the washer.
Solution: Fix the Speed Sensor
Before fixing the speed sensor, you might want to inspect the washing machine to ensure that the problem comes from the speed sensor. Once you’ve gotten that correctly, you will have to replace the faulty speed sensor.
To gain access to the speed sensor:
- You will have to remove the rear access panel.
- Then take off the rotor from the tub,
- Remove the screws securing the stator wire retainers and bracket, plus the grounding screw
- To remove the stator, take out the bolts that hold it in place, then disconnect the motor sensor wire harness.
- Finally, remove the old sensor.
- With that done, replace it with the new sensor in the same location
- When done, fix everything backward and check if it works.
3. Failed Main Control Board
The main control board is the center of the washing machine. This printed circuit board features tons of tiny electronic components on it. Depending on your settings, the controller determines the runtime of the cleaning cycles and how every other feature of the washing machine functions.
Over time, issues will arise with the control. A possible occurrence is when it shorts out due to a power surge. Other possible occurrences could be exposed to heat or moisture causing it to wear out sooner. If the main control board’s components are damaged, some parts of the washer will stop working which could stop the washer from spinning.
Solution: Fix the Main Control Board
If you notice that the main control board is faulty, then you should get a replacement. While some people would want to repair the main control board, it is most likely to develop a new fault in the future if you go with that process.
4. Motor Rotor Assembly Worn Out
The motor rotor assembly sits towards the rear of the washer. It attaches to the tub inside and spins it around. The motor rotor assembly needs to be attached to the shaft for this to happen correctly. if the motor rotor assembly is worn out, the LG washer won’t spin correctly. You might hear a grinding noise but not spinning.
Solution: Fix the Motor Rotor Assembly
The motor rotor assembly should be replaced. To do this,
- Remove the access panel.
- When done, you will see the rotor assembly
- Remove the bolt that holds the old assembly in place and put the replacement on. Tighten the bolt
- Turn the rotor assembly by hand to confirm that it engages with the tub and spins it as well.
5. Drain Pump or Filter Clogged
The drain pump is designed to remove all the water from the machine once the washing cycle has completed while the filter helps to remove dirt from the washer to avoid clogs.
If the drain pump or the filter gets clogged, the LG washer will not be able to drain out water which will cause the washer not to spin.
Solution: Clear the Drain Pump or Filter
To clear the drain pump or filter:
- Locate the small panel on the front of the machine right at the bottom. This hides the drain pump filter
- Inside the panel, you will find a small drain hose. The hose allows you to drain all the remaining water out of the washer.
- Once drained out, remove the drain pump filter and wash it. Ensure all the dirt and particles are removed before fixing it back in the machine.
6. Wash Load is Off Balance
In some cases, the washer won’t be able to spin if the wash load is unbalanced. This might occur if you’re trying to wash too many things at once.
Solution: Balance The Wash Load
To fix an unbalanced large road, redistribute items to the other side of the tub while removing some items. Avoid piling up a bunch of stuff on one side of the washing machine. Always refer to the manual as to the load capacity and the right load distribution.
