Usually, turning that knob will automatically turn the washer on as well. If nothing happens when you press on the power button, then try turning the cycle selector. Here’s an easy way to troubleshoot this problem. It’s just that when you press the power button to turn it on, the machine isn’t getting the signal to turn it on and do its job. Here’s another way to look at it: your washer is probably working just fine. Why it fails: If you’re unable to turn on your LG washer, it could be due to a failure of the microswitch behind the power button. That will send a sort of signal to the control board, telling the washer what to do. When you press on a button, say the power button on your washer’s control panel, what you’re doing is applying pressure onto a microswitch. That’s why appliances like your LG washer will have a microswitch behind each of the buttons you press to input your settings. What it is: As the name suggests, a microswitch is simply a tiny switch that doesn’t take much effort to actuate. Lastly, secure any panels you removed and reconnect the machine to its power and water supplies.Then, simply mount the new noise filter in place and reconnect the wire harness.You might find the noise filter assembly mounted on the washer’s sidewall with screws or bolts that need to be removed. Then, remove whichever panel will give you access to the noise filter.That will help you locate and identify the noise filter, which might be in different locations depending on your washer model. Refer to the user manual or any technical sheet that the manufacturer may have included with the washer.That’ll reduce the risk of injury and prevent electrocution. How to fix: Before performing any repairs to a washer, you must disconnect the power and water supplies. A common reason for that would be power surges during thunderstorms. That includes electrical parts like the noise filter as well.īesides that, there’s a possibility that the noise filter may have shorted out. Like any other component in your LG washer, long-term use can lead to parts getting worn out and needing replacement. Typically, a noise filter might fail if it has either worn out or short-circuited. Or, more likely, you’ll find that the LG washer control panel won’t turn on. Firstly, you might hear audible static noises from the washing machine. Why it fails: There are two clear signs that your noise filter has failed. Replace the access panels you removed earlier.Refer to the photo you took earlier to avoid any mistakes. Then, put the electrical connectors back precisely the same way as before. Remove the control board and put in the new one.That way, you’ll have a reference photo you can use later. Take a picture of the control board before removing it.Remove the necessary panels to gain access to the control board.Typically, it’s behind the front control panel. Refer to the user manual and locate the control board. Disconnect the power supply to the washer.Replacing the control board is a fairly straightforward process. If that’s the case, then the problem may be with the noise filter (explained later in this article), or you might need to replace the control board. For others, it may only work as a short-term solution, or it may not work at all. Plug the washer back into the power supply.įor some users, this reset is all that’s necessary.Press the play/pause button for 5 seconds.That is commonly referred to as the “ 5-second reset”, and it’s effortless to do. How to fix: Before attempting any kind of fix, the first thing you should do is try a reset of your LG washer. While it is still possible, the likelihood is relatively low when it comes to reputable brands like LG, which have high-quality control standards. The least common reason for the PCB failing is defects or poor design. Perhaps the PCB was somehow exposed to too much heat, moisture, or dust.Įlectrical surges, such as those that happen during thunderstorms, can also cause damage to the PCB. So, if you r LG washer has been in use for a long time, it could simply be that the circuit board has suffered from wear and tear and requires a replacement.īesides that, it’s also possible that environmental factors are to blame. There are several reasons why a control board might fail. But, of course, if the problem is severe, the entire machine will not turn on at all.
