Reasons Why LG Washer Won’t Turn On: How to Troubleshoot and Fix
1. Main Printed Circuit Board (PCB).
The main Printed Circuit Board (PCB) is the “brain” of your washer. All the data and commands from all the buttons are sent to this board to tell the washer what to do. If this board fails, it will cause your washer to fail as well.
There are a few things that can cause your main PCB to fail. The most common is a power surge. This can happen if there is a power outage or if you have an electrical storm. If this happens, it can damage the components on the board and cause it to fail.
Another thing that can cause your main PCB to fail is if it gets wet. This can happen if there is a leak in your washer or if you spill something on it. If this happens, you will need to replace the main PCB.
How to fix it?
If your main PCB has failed, you will need to replace it. You can do this yourself if you are handy with tools and have some experience working with electronics. If you are not comfortable doing this, you can call a repairman to do it for you.
Replacing the main PCB is not a difficult task, but it is important to make sure that you get the right replacement board. You will need to find the model number of your washer and then order the correct PCB from the manufacturer.
Once you have the new PCB, you will need to remove the old one and install the new one. Make sure that you disconnect all the wires before you remove the old PCB. Once the new PCB is in place, you can reconnect the wires and test your washer to make sure it is working properly.
2. Noise Filter.
The noise filter is a small, round, black disc that helps to reduce the amount of electromagnetic interference (EMI) that can cause your washer to function improperly.
Why does it fail?
The noise filter can fail due to a power surge, age, or extended use.
How do you know it’s the noise filter?
If your washer is not turning on, and you have checked that the power cord is plugged in correctly and that there is power to the outlet, then the noise filter may be the culprit.
How do you fix it?
If your LG washer won’t turn on, or if it’s not working properly, you may need to replace the noise filter.
To replace the noise filter:
- Unplug the washer from the power outlet.
- Remove the back panel of the washer.
- Locate the noise filter and remove it.
- Replace the noise filter with a new one.
- Reattach the back panel to the washer.
- Plug the washer back into the power outlet.
3. Power Button Microswitch Lost Connection.
If your power button is not working, it may be due to a loose connection. The most likely culprit is the power button microswitch.
This switch is responsible for sending a signal to the control board that tells it to turn on the washer. If this switch becomes loose, it can lose its connection and prevent the washer from turning on.
To fix this, you will need to replace the power button microswitch. This is a relatively easy repair that can be done with a few tools. You can find the power button microswitch at most hardware stores or online.
Once you have the new switch, simply remove the old one and install the new one in its place. Make sure that the new switch is properly connected and then try turning on the washer.
4. Power Source.
About this: If your machine is plugged in but won’t turn on, check your power source. Make sure the washing machine is connected to a working outlet with the correct voltage.
Why does it fail?
A power outage can cause your washing machine to fail. If the outlet is not getting power, check circuit breakers or fuses.
If the outlet is getting power, but the washer still won’t turn on, the problem is likely with the washing machine itself.
5. Start Button is stuck.
If your LG washer’s start button is stuck, it could be due to a number of different issues. First, check to make sure that the power cord is plugged into an outlet and that the washing machine is turned on.
If the machine is turned on but the start button won’t budge, there may be something blocking it from moving.
Try moving the washer to a different location and see if that frees up the start button. If not, there may be an issue with the washing machine’s control panel.
6. Hard Reset.
If your LG washer won’t turn on, a hard reset may be the solution. This will clear any errors that may be preventing the washer from functioning properly.
To do a hard reset, simply unplug the washer for at least 30 seconds. Then, plug it back in and try to turn it on again. If this doesn’t work, you may need to call a repair technician.
7. Line Fuse.
The line fuse is a safety device that trips if the current flowing through it becomes too high. This usually happens if there is a short circuit somewhere in the washer’s electrical system.
Why does it fail?
The line fuse usually fails because of a manufacturing defect.
What are the symptoms?
If the line fuse trips, the washer will not start.
How do you fix it?
If the line fuse has blown, you’ll need to replace it before your washer will work again.
Replacing the line fuse is a pretty easy job that anyone can do. Just follow these steps:
- Unplug the washer from the power outlet.
- Remove the access panel on the back of the washer.
- Locate the line fuse and unscrew it from its holder.
- Replace the fuse with a new one of the same amperage rating.
- Screw the fuse back into its holder.
- Replace the access panel.
- Plug the washer back into the power outlet.
8. Circuit Breaker.
If your washer won’t turn on, the first thing to check is whether or not the circuit breaker has tripped.
If it has, simply reset it and try again. If that doesn’t work, you may need to call an electrician.
Why does it fail?
There are a number of reasons why a circuit breaker might trip, but the most common one is simply that the washer is drawing too much power.
This can happen if there’s a problem with the wiring, or if the washer is overloaded.
9. User Control and Display Board.
The user control and display board is the part of the washing machine that houses the buttons and controls for operating the washer, as well as the display panel that shows cycle settings and progress.
If your washer won’t turn on, it may be because there is a problem with this board.
Why does it fail?
There are a few reasons why the user control and display board might fail.
One possibility is that there is a problem with the washing machine’s power supply. Another possibility is that the board itself has become damaged or malfunctioning.
How to fix it:
If you think that the user control and display board is the reason your LG washer won’t turn on, there are a few things you can try to fix the problem.
First, check the washing machine’s power supply. Make sure that it is plugged in and that the circuit breaker hasn’t been tripped.
If everything looks good there, try resetting the board by unplugging the washing machine for a few minutes and then plugging it back in.
If neither of those solutions works, you may need to replace the user control and display board. This is a relatively easy repair that can be done by following these instructions.
10. Child Lock Feature.
If your LG washer won’t turn on, it may be due to the child lock feature being enabled. To disable this feature:
-Press and hold the Child Lock button for three seconds.
-The display will show CHILD LOCK OFF when the feature is disabled.
11. Timer.
If your LG washer won’t turn on, the first thing to check is whether the timer is set. If it is, try advancing it to see if that helps. If not, you may need to replace the timer. Fortunately, this is a relatively easy repair that you can do yourself.
To replace the timer, first disconnect the power to your LG washer. Then, remove the control panel by unscrewing the screws that hold it in place. With the control panel removed, you should be able to see the timer.
Unscrew the timer and pull it out. You can then install the new timer by screwing it into place. Once it’s in, just reattach the control panel and turn on the power. Your LG washer should now be working properly.
12. Lid Switch.
The lid switch on your LG washing machine is a safety feature that prevents the washer from operating when the lid is open. If your washer won’t turn on, it may be because the lid switch is faulty or not working properly.
Why does it fail?
There are several reasons why the lid switch may fail. The most common reason is because the switch itself is worn out or damaged. Another possibility is that the wiring to the switch is damaged or loose.
If you’re having trouble with your LG washer, one of the first things you should check is the lid switch.
How to test the lid switch?
First, make sure that the washer is unplugged and the lid is open. Then, locate the lid switch. It’s usually a small button or switch located near the top of the washer.
Once you’ve found the lid switch, test it to see if it’s working properly. To do this, simply press and release the switch. If the switch is working properly, you should hear a click. If you don’t hear a click, or if the switch feels loose or broken, it needs to be replaced.
To replace the lid switch, you’ll need to order a new one from LG. Once you have the new switch, follow the instructions in your owner’s manual to install it.
13. Control Panel.
The control panel is the most important part of your washer. It houses the controls for all the functions of your machine.
If your LG washer won’t turn on, it’s likely due to a problem with the control panel.
Why does it fail?
There are a few reasons why the control panel might fail. First, the power supply could be interrupted. Second, there could be a problem with the control panel itself. Third, the washing machine’s main circuit board could be damaged.
There are a few things you can try to fix this problem:
First, check to make sure that the control panel is properly plugged in. If it’s not, plug it in and try again.
Next, check the fuse box to see if a fuse has blown. If so, replace the fuse and try again.
14. Power Cord.
If your LG washer won’t turn on, one possible reason is that the power cord is not properly plugged in.
Check to make sure that the power cord is plugged into a wall outlet and that the washer is turned on at the breaker box. If neither of these are the problem, then you may need to replace the power cord.
If you have determined that the power cord is the problem, you can purchase a new one from an appliance store or online.
Be sure to get the correct power cord for your model of LG washer. Once you have the new power cord, simply follow the instructions in your owner’s manual to install it.
15. Door Lock.
If your LG washer won’t turn on, the first thing you should check is the door lock. This is a safety feature that keeps the washer from operating if the door is open.
If this is not the problem, there are a few other things you can try.
First, unplug the washer and wait a few minutes. This will reset the washer and may fix the problem.
If this doesn’t work, you can try opening and closing the door several times. Sometimes this will loosen the door enough to get it to close properly.

LG Washer Won’t Turn Off?
If your LG washer won’t turn off, it may be due to a power surge. To fix this, unplug the washer from the power outlet and then plug it back in. If that doesn’t work, try resetting the washer by pressing and holding the “Start/Pause” button for five seconds.
If the above solutions don’t work, then there may be a problem with the washer’s control panel. If this is the case, you’ll need to contact LG customer service for further assistance.
LG washing machine touch screen not working?
One possibility is that the washing machine’s display board has become loose. To fix this, simply remove the screws holding the board in place and reattach it.
Another possibility is that something is blocking the sensors on the touch screen. This can be anything from dust to fingerprints. Simply cleaning the screen with a soft cloth should fix the problem.
If neither of these solutions work, then it is possible that the touch screen itself is damaged and will need to be replaced. Luckily, LG offers a one-year warranty on all parts and labor, so this should not be a problem. Simply contact customer service and they will help you get a replacement.
LG washer won’t turn on unless unplugged?
Let’s take a look at some of the most common causes and how to fix them.
One of the most common causes of this problem is a faulty door switch. If the door switch is not working properly, it will prevent the washer from turning on. To test the door switch, simply open and close the door a few times. If the washer turns on and off as you do this, then the door switch is most likely the problem.
Another common cause of this problem is a faulty lid switch. The lid switch is located under the top of the washer near the lid. If this switch is not working properly, it will also prevent the washer from turning on.
To test the lid switch, simply lift and lower the lid a few times. If the washer turns on and off as you do this, then the lid switch is most likely the problem.
If neither of these switches are the problem, then the most likely issue is a problem with the washer’s power cord. Check to make sure that the power cord is plugged into an outlet and that the outlet is working properly. If the cord seems to be fine, then check for any loose or damaged wires.
LG Washer Won’t Stop Running?
If your LG washer won’t stop running, it could be caused by a few different things. The most common cause is that the washer isn’t draining properly. If this is the case, you’ll need to clean out the drain pump filter and make sure nothing is blocking the drain hose.
Another possible cause is that the water level sensor is faulty. To fix this, you’ll need to replace the water level sensor.
Finally, if your LG washer won’t stop running, it could be because the door isn’t closing properly. If this is the case, you’ll need to adjust the door strike or replace the door gasket.
Conclusion
If your LG washer won’t turn on, there are several potential causes. First, check to make sure that the washer is plugged in and that the outlet is working. Next, check the water supply valves to ensure that they are turned on.
If these two things are not the problem, then there may be an issue with the washer’s door lock mechanism or a problem with the washer’s control panel.
If you are still having trouble, then it is best to contact a qualified LG repair technician for assistance.
