LG Washer Won’t Turn On/Turn Off/Start/Stop Running

LG washers break down from time to time, even if you’re on top of the basic maintenance routines that they recommend. Although some may need a replacement or major repair, it would be best to know how to deal with it yourself, right?

LG washers that won’t turn on or off may only need a hard reset. It can also tell you why it won’t start or stop running. To do a hard reset, unplug the washer, press the power button for 5 seconds, then release. Press the start button for 5 seconds, plug it back, and see if it solves the issue.

Hard resets can solve many of the problems that you’ll experience with an LG washer. But we’ll discuss more of these issues in great detail and show you how you can fix them.

LG Washer Won't Turn On: Causes & How to Fix

Often, you can fix an LG washer that won’t turn on by doing a hard reset. However, before you jump into troubleshooting your washer, it would be best to test if power is getting to it.

The first test you can do is check the same outlet with another electronic device and see if it delivers power. If it also doesn’t turn on, then you’ll need to check your circuit breaker. Here’s how to do it:

  1. See if the correct switch is on.
  2. If the switch is on, try resetting the circuit breaker.
  3. Unplug everything that is connected to the line.
  4. Turn it off for 5 seconds, then turn it back on.
  5. Plug the washer back and see if this solves the problem.

If your LG washer still won’t turn on despite having power from the outlet, the first troubleshooting step is to unplug it for a few minutes, then plug it back in. It resets the washer and can solve many of the issues you’re having with an LG washer.

If a reset doesn’t solve the issue, then it’s time for you to do a hard reset. It resets the main control board and often shows you an error code, making it easier for you to identify the problem and find the proper fix for it.

If all of these didn’t solve the problem and you’re not getting any error code from the display, you may have to proceed with replacing the control panel (cheapest) or the main control board (most expensive).

LG Washer Won't Turn Off: Causes & How to Fix

LG washers that won’t turn off are easier to troubleshoot and repair than those that won’t turn on. If it has power, you can easily check the buttons and do tests that you can’t do if there’s no power going in your washer.

The first step you can do is to unclog your washer and wait for a few minutes before plugging it back in. Again, it resets the washer and could be an easy way to fix it. Although it doesn’t often fix the problem, it’s still the first that you should try because it doesn’t cost anything. Remember, if you’re trying to troubleshoot or repair electronic devices, you should always start with the cheapest and easiest steps. 

If it still won’t turn off, try pressing different buttons, and see if everything works. If every button works, then you can try doing a hard reset with your washer. If some of the buttons don’t work, you may have to replace your control panel to fix the problem.

If a hard reset doesn’t fix the problem or if your washer doesn’t turn off automatically, then you may have to replace the circuit board. Small relay switches control everything in your washer—it’s responsible for automating the process from filling to draining the water.

However, over time, these relays may get welded together, turning it into a fixed contact rather than a switch. These switches could be the reason why you can’t turn your LG washer off, automatically or manually.

LG Washer Turns on but Won’t Start Running: Causes & How to Fix

LG Washer Turns on but Won't Start Running: Causes & How to Fix

LG washers that turn on but won’t start running is easier to troubleshoot and cheaper to fix. The problem is often with the lid switch or the lid itself—depending on the model you have.

LG washers have a safety feature that prevents it from running if the lid isn’t closed. This feature could be a switch that comes into contact with the lid once you close it, or the lid itself is directly connected to the main control board.

If you have a faulty lid switch, your washer may turn on, but it won’t run even if the lid is closed. The same is true for a lid connected to the main control board; even if you close it, the connection is faulty, so the system won’t know that it’s already closed.

To determine whether you need to replace the switch or the main control board, open your washer lid and close it gently. If you can’t hear or feel a “click” as you close the lid, you may have to replace the lid switch to fix the problem.

However, if you can hear or feel a click as you close the lid, you may have a faulty connection from the lid to the main control board. If this still doesn’t solve the problem, replacing the main control board could be the only solution that you have to get it to run again.

LG Washer Won’t Stop Running: Causes & How to Fix

LG Washer Won't Stop Running: Causes & How to Fix

There are three common reasons why an LG washer won’t stop running: water valve, pressure switch, or the main control board. However, like most LG washer problems, the first step is to reset it by unplugging for a minute then plugging it back in. If it doesn’t solve the problem, try a hard reset and see if it shows you an error code that you can use to determine the problem. If both didn’t work, you’d need to repair/replace some parts of your LG washer.

A faulty water valve causes the washer to continuously fill the drum with water and won’t stop even if it’s unplugged! The water valve is responsible for closing the water source, but if it fails, the only way to cut it off is to close the waterline. To fix this, you only need to replace the water valve with a replacement for your model.

If replacing the water valve doesn’t fix the problem or only runs when the LG washer is plugged in, you may have to replace the pressure switch or water level control. This part is responsible for letting the machine know that it already has enough water. If it fails, your washer will keep filling with water, or the drain pump won’t stop running.

The last step that you can do is to replace the main control board, similar to other issues that we’ve discussed. This step is always the last because it’s one of the most expensive parts of the washer. An LG main control board costs $200 or more, depending on the model you have. At this point, depending on how long you’ve used your washer, getting a new one could be a better option than trying to replace the main control board.

Final Thoughts

LG washers, regardless of how you take good care of them, will break down from time to time. But you can fix most of these problems with a reset or hard reset. It uses a sophisticated system with several moving parts, and if one goes wrong, the whole system fails. A reset sends a signal to every part of the washer, often enough to get it running again.

Sometimes, you need to replace some parts of the washer to get it to work, but this can cost up to hundreds of dollars, so this is often a last resort.
