How to Turn Off a Stuck Child Lock on Your LG Washing Machine
Press and hold the Child Lock button (or the designated button combination shown in your model's manual, often 'Temp' + 'Option') for 3–5 seconds until the CL indicator disappears and the panel responds normally (takes about 2 minutes).
Fault description
When the child lock is active on an LG washing machine, the control panel becomes unresponsive — buttons won't register, programmes can't be changed, and the machine may appear completely frozen. You'll usually see the letters CL displayed on the screen, which is LG's indicator that the child lock feature is engaged. This is a safety function designed to prevent accidental changes to a running cycle, particularly useful in homes with young children.
In most cases this isn't a fault at all — the lock was activated intentionally or accidentally by holding a button too long. However, if the CL code won't clear after following the correct deactivation steps, there may be an underlying issue with the control board or a stuck button. Working through the steps below will help you identify which situation you're dealing with.
Causes
- Child lock accidentally activated — The most common reason is that the child lock was triggered unintentionally — often by leaning against the panel, a child pressing buttons, or holding a key slightly too long during normal use. The CL code will display and all buttons will appear dead until it is deactivated.
- Incorrect deactivation method — Different LG models use different button combinations to toggle the child lock on and off. Pressing the wrong button or not holding it for long enough (typically 3–5 seconds) will leave the lock in place, making it seem stuck when it simply hasn't been released correctly.
- Sticky or physically stuck button — Detergent residue, moisture, or general wear can cause a button to stick in a partially pressed position. If the child lock button itself is stuck down, the machine may continuously re-engage the lock as soon as you try to clear it.
- Temporary control board glitch — A brief software or firmware glitch in the main control board can cause the panel to become unresponsive or lock itself unexpectedly. A power reset usually clears this type of fault without any parts replacement.
- Faulty main control board — In rare cases, a failing PCB (printed circuit board) can cause the child lock state to become permanently stored or the panel to stop responding to input altogether. This is uncommon and is usually only suspected after all other steps have been ruled out.
Step-by-Step Fix
- 1
Identify the correct child lock button for your model
Check your user manual or the label printed on the control panel itself — LG machines vary by model. On many models the child lock is deactivated by holding the 'Child Lock' button alone, while others require holding 'Temp' and 'Option' simultaneously. If you don't have the manual, search your model number on LG's support website to find the correct combination.
- 2
Hold the button combination for a full 3–5 seconds
Press and hold the correct button or button pair firmly and continuously. Don't tap — hold it. After 3–5 seconds you should hear a beep and the CL indicator will disappear from the display. If it clears, test a few buttons to confirm the panel is responding normally before running a cycle.
- 3
Power cycle the machine
If the CL code remains after step 2, turn the machine off using the power button, then unplug it from the wall socket. Wait at least 60 seconds to allow the control board to fully reset, then plug it back in and power it on. Try the deactivation button combination again — a power reset resolves many temporary software glitches.

Inspect the child lock button for sticking
With the machine unplugged, press the child lock button several times and feel whether it springs back cleanly. If it feels sticky or doesn't return fully, dampen a cloth with warm water and gently clean around the button edges. Avoid spraying water directly onto the panel. Allow it to dry completely before restoring power.
- 5
Check for a demo or showroom mode
Some LG models have a separate demo mode that can mimic a locked panel. Refer to your manual to confirm whether demo mode is active — it is usually deactivated by holding a specific button combination for 5 seconds. This is easy to confuse with the child lock if you're unfamiliar with the machine.
- 6
Perform a factory reset if available
Some LG washing machine models support a full factory reset that clears all stored settings including any locked states. Check your manual for the reset procedure — it typically involves holding multiple buttons simultaneously for 5–10 seconds. Note that this will clear any custom programme settings you have saved.
- 7
Test the control panel systematically
If the CL code has cleared but certain buttons still don't respond, press each button individually and note which ones are unresponsive. A pattern of dead buttons in one area of the panel points to a faulty membrane or control board rather than a child lock issue, and at this point a service technician should assess the machine.
When to call a service technician
If you have followed every step above — including a power reset and the correct button combination for your specific model — and the CL code still won't clear, or the panel remains completely unresponsive, it is time to contact a service technician. A persistently locked panel that doesn't respond to any input suggests the control board may have failed or the button membrane has broken down internally.
You should also call a service technician if the child lock deactivates but then re-engages on its own without anyone touching the panel. This points to a stuck button or a control board fault that is continuously re-triggering the lock, and it will not resolve itself without a physical inspection and likely a component replacement.
Prevention
The child lock on LG washing machines is a reliable feature that rarely causes genuine faults. To avoid accidentally activating it, be mindful when wiping down the control panel — a cloth held against a button for a few seconds is enough to trigger it. If you have young children, consider using the child lock intentionally during cycles and making a note of the deactivation method for your specific model so you can clear it quickly when needed.
The parts most commonly replaced when the child lock issue turns out to be a hardware fault are the main control board (PCB), the control panel membrane or button assembly, and occasionally the display board. You can find compatible parts for your LG washing machine model using the tool below.

Frequently Asked Questions
What does CL mean on my LG washing machine?
CL stands for Child Lock. It is displayed on the screen whenever the child lock feature is active, indicating that the control panel buttons have been disabled. It is not an error code indicating a mechanical fault — it simply means the lock needs to be deactivated using the correct button combination for your model.
My LG washing machine buttons are completely unresponsive — is it definitely the child lock?
A fully unresponsive panel is the most common sign of an active child lock, but it can also be caused by a control board glitch or a power supply issue. Start by checking for the CL indicator on the display. If CL is showing, follow the deactivation steps. If the display is blank and there is no CL code, check that the machine is receiving power and try unplugging it for 60 seconds before powering it back on.
Can I run a wash cycle with the child lock active?
Yes — on most LG models, a cycle that was already running when the child lock was activated will continue to completion. The child lock prevents changes to settings and new programme selections, but it does not stop an in-progress wash. Once the cycle finishes, you can deactivate the lock using the correct button combination.
Why does the child lock keep turning itself back on?
If the child lock re-engages without anyone pressing the buttons, the most likely cause is a sticky or partially stuck button that is registering a long press on its own. Clean around the button carefully with a damp cloth and check that it springs back freely. If the problem continues after cleaning, the button membrane or control board may need to be replaced by a service technician.
Will unplugging my LG washing machine clear the child lock?
On most LG models, the child lock setting is stored in memory and will still be active when the machine is plugged back in. However, a power reset can clear temporary software glitches that make the panel unresponsive, which may allow the deactivation button combination to work correctly afterwards. You still need to follow the proper deactivation steps after restoring power.
