We’ll go over the most frequently-cited reasons for why the LG washer isn’t spinning and give you step-by-step instructions on how to fix the issue. We will address every aspect, from a worn belt to a malfunctioning lid switch. This can save you time and money. If your LG washer isn’t agitating you’re worried. We’ll help you resolve the issue.



In the top loading washer of LG the agitator moves clothes through water and detergent. It is powered by the output shaft of the transmission. The output shaft is normally splined, and the center of the plastic agitator has an spline with a similar shape to ensure that it is a perfect fitting. The brand of the agitator will determine whether the agitator may be a single piece unit or a dual-action two-piece agitator. How to check the agitator of the LG washing machine:

  1. Unplug the LG washing machines from power sources.
  2. Remove the fabric softener dispenser or top cover, depending on the model you have, in order to access the agitator. Try turning the agitator. You should feel some resistance as it gets moved.
  3. Remove the agitator from the appliance in order to examine it with greater precision. Most agitators are held into place with a bolt that runs through the top of the shaft. Certain models utilize a tiny set screw inside the barrel of the agitator, just above the base to anchor the agitator to shaft, while some will employ a rubber O-ring in order to provide a tight fit.
  4. You’ll need a new LG agitator when your agitator is damaged or worn on one of its components, particularly around the splines.



Agitator Directional Cogs:

On top loading LG washers that use an agitator with dual actions it’s possible for the top part of the agitator be disengaged from the bottom portion. Cogs that are made of plastic and hard also known as “dogs” operate the upper portion of the agitator. They are susceptible to wear and tear because of heavy usage. The directional cogs can wear out if they are in the upper part of the washing machine’s agitator is not turning in the correct direction or if it makes a loud noise in the course of washing. How to test the directional cogs in the LG washer:

  1. Unplug the LG washing machine and then take out the fabric softener dispenser or top cover, depending on your model.
  2. Locate your agitator cogs. You may need to remove the cap, base or top, depending on your model for access to the cogs.
  3. Take a look at the cogs and see if there are any marks, wear or damages. Also, ensure sure there are no cogs missing.
  4. If your cogs exhibit any of the signs mentioned above, you will need a set of LG replacement cogs for directional use.


Agitator Coupler & Cap & Bolt:

Some models of top loading washers from LG use a coupler between the transmission shaft and the agitator. To match the transmission, the drive coupler is split in the inside and out. The drive coupling may be damaged if the LG washer produces noises of grinding in wash cycles or if the agitator is not turning freely. How to test and replace the agitator coupler on a LG washing machine:

  1. Before you begin the inspection, shut off your LG washer.
  2. To access the agitator coupler you’ll first need to take off the top cover or fabric softener dispenser, based on the model. After that, you’ll need to remove the agitator.
  3. Unthread the bolt that connects the coupler to the transmission shaft and then remove it from the appliance. Inspect the coupler for cracks or wear, burnt, rust, and damage.
  4. You’ll require a LG replacement coupler in the event of one of these problems.


Direct Drive Motor Coupling:

Some top load LG washers have direct drive motor coupling that transfers energy from the motor to the transmission. The drive coupling made comprised of two drive forks, as well as a rubber coupling. It connects the motor to the transmission. One drive fork is connected to the drive motor shaft while the other one is connected to the shaft of the transmission’s input. The rubber coupling that connects the drive forks absorbs torque created by the motor shaft’s rotating to prevent the forks from breaking. The normal use of the coupling will cause wear on the coupling and eventually the drive forks could slip and not engage the clutch and transmission. One indicator of a broken motor coupling in a LG washer machine is that it fills and drains normally, but doesn’t spin or agitate. How to check the direct drive motor coupling in a LG washing machine

  1. Before you begin, unplug the appliance from the main power supply.
  2. Locate and remove the motor coupling to inspect it. You’ll need to open the LG refrigerator to access it. In accordance with the model it is possible to remove the drain pump or motor.
  3. After you’ve removed your object, inspect the coupling closely for signs of wear, scratching cracks, cracks, etc.
  4. You’ll require a replacement direct motor coupling LG should you experience any of the following symptoms.


Drive Belt:

Top loading LG washers are fitted with belts that drive the transmission. If the machine isn’t moving as it should, then the belt is at fault. How do you determine whether the drive belt of aLG washer needs replacement:

  1. Unplug your LG washer and then take it off the cabinet or access panel to find the drive belt.
  2. You can disconnect the clamps that secure the belt into place, and then remove the drive belt from the drive motor.
  3. Examine the drive belt visually. Examine for wear, fraying or other indications of damage to the drive belt.
  4. If your belt shows any of these symptoms as described above, you need an LG replacement drive belt.



The transmission of LG’s top load washer converts the motor’s rotational motion into the back and forth motion that is required to drive the agitator. Transmissions have an input shaft which is driven by the motor directly or through a belt. An output shaft drives the agitator. Make sure that your drive shaft for the agitator is oscillating well before replacing it. The transmission may be not working properly If the input shaft spins however the agitator shaft does not turn. Most manufacturers do not offer the internal components needed for a complete transmission. It is essential that you can replace the tub seal at the point where the shaft goes into the tub. How to examine the transmission of a LG washing machine: Before you begin to inspect your machine check to ensure that the problem isn’t due to the agitator or other components.

  1. If you’ve eliminated the agitator, disconnect your washer, open the cabinet and locate the transmission.
  2. After you’ve located the problem with your transmission, plug your washing machine back into the circuit and run a wash cycle to determine if the transmission is the reason for the issue. You might hear unusual sounds when the transmission is damaged. Be cautious when you perform this procedure since the internal components of your dryer are exposed.
  3. If your transmission is noisy during this test, then you require a LG replacement transmission.


Drive Motor:

All top load washers made by LG have a motor to drive the motor for agitation. LG washers are equipped with a reversing motor. This means that the motor turns in one direction for spinning and draining , and in the other direction to create agitation. Motors could operate in the direction of spin, but not towards the direction of the agitation. What is the procedure to check the drive motor inside the LG washing machine:

  1. Before you begin, disconnect the power source from your LG appliance.
  2. To locate the drive motor, unplug the cabinet from your LG washer. To remove the motor from your appliance, you’ll need to pull those connectors instead of the wires.
  3. The multimeter must be set to Rx1 mode. Verify continuity by placing the probes onto the motor’s terminals. A reading should be close to or at zero.
  4. To test the ground connection test the ground connection, place one probe on the terminal, and then place the other on the metal housing of the motor drive. You shouldn’t get any result from this test.
  5. It is necessary to replace the LG drive motor when your readings differ from those described above.



The drive motor is controlled by the timer, lid switch, water level switch, and occasionally the selector switch. The purpose of the timer is to supply the proper amount of power needed to start the motor in the right direction. If the drive motor in your washer does not receive electricity during the wash phase of the cycle, the timer might be to blame. How do you test the timer on the LG washing machine using a multimeter:

  1. Similar to most repairs begin with disconnection of your LG washer from its electrical source.
  2. To locate the timer, you must remove the control panel of the appliance and the rear panel.
  3. Take care to disconnect the wires attached to the timer by pulling on the metal connectors and not the wires, and remove the timer from its washer to test it.
  4. By using a multimeter on the Rx1 settings, make sure you connect the probes with the terminals that control the motor (refer to your wiring diagram) to verify continuity. You should get a reading of zero or nearly zero. If you don’t see this reading, you’ll need a LG replacement timer.


Lid switch:

The lid switch is a security feature that is available on top-loading LG washing machines. The switch for the lid is normally found beneath the main top and is connected to the motor circuit and must be activated for the motor to operate. When the lid is closed a projection or pin on the lid pushes against the lid switch lever and shuts off the switch. The lid switch should be checked if your LG washer isn’t moving or the motor doesn’t have any electricity. How to test the switch that controls the lid on the lid of aLG washer:

  1. Start by disconnecting the LG washer. Then, take off the top panel.
  2. Find the switch , and make sure it’s activated when you close the lid. If it is, remove the switch in order to test it.
  3. Change your multimeter’s setting to Rx1 and make sure you touch the terminals with the probes. Press the button, and hold it down. The multimeter should read or close to zero.
  4. You’ll need a new LG lid switch in the event that your test results are not the same.


Selector Shift:

Some models have a selector switch that controls the speed of motor. The motor may not be able to start in the event of a damaged switch. How do you test the selector switch on aLG washing-machine using a multimeter

  1. Before you start using electrical components, unplug the electrical components in your LG washer.
  2. Locate the selector switch on your LG appliance and pull it out. It likely will be secured to the frame of the LG washing machine. To gain access to the cabinet you’ll need to remove the entire cabinet or a portion.
  3. With a multi-meter set to the Rx1 setting, you’re going test each button for continuity. Press the first button to alter the reading from zero to infinity. Keeping the probes connected to the terminals, press in on a different button, the reading should change back to infinity.
  4. If the results of your test differ from those above You will require a LG replacement switch for the selector.



Water Level Switch:

The water level switch is situated on top load LG washers. It allows you to select the correct level of water. It also functions to supply power to the drive motor. The switch shuts off the valve for water inlet to decrease power consumption, and provide power to the motor’s circuit. If the washer fills up but does not move, the pressure switch could be the cause. Test the water level switch on aLG washing machine.

  1. Disconnect the power supply from the LG washer.
  2. The switch for water level will be found typically behind the control panel, but it may also be found below the tubs in the sump region.
  3. Before switching the switch, eliminate the air dome hose to determine the cause. In the water, submerge the hose and make sure it is sealed. After that, blow air through the other end, and look for bubbles. Also, inspect for issues or signs of wear.
  4. If you do not find any issues in the air dome hose you might need an LG replacement water level switch.
