CL is not an error code. You accidentally activated the Child Lock feature. To turn it off: press and hold the Child Lock button (or the button combo for your model) for 3 seconds until CL disappears.
Honestly, this is the call I get more than any other that turns out to be nothing. CL means child lock is on. Your washer is perfectly fine. If you just ignore it, the panel stays locked and you can't change anything, but the machine keeps running whatever cycle it was already on. You can clear it in about 10 seconds once you know the right button. No parts, no repair guy, no cost whatsoever.

What Does the CL Code Mean?
OK so here's the deal - CL is not an error. Not a fault. Not your washer dying on you. It's a feature that got switched on, probably by accident. I've gotten panicked texts about this at 9pm from people convinced their washer just gave up the ghost. It didn't. There's no repair cost, nothing to order. Hold one button for 3 seconds and you're completely done. This is probably the single most common thing I get called about that takes less than a minute to fix.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
User accidentally held the Child Lock button during a cycle40%
Child pressed buttons in a combination that triggered Child Lock24%
CL activated by holding Start/Pause for extended period on some models22%
Control panel cleaned with CL button held down14%
Symptoms You May Notice
CL shows on the display and just sits there no matter what button you hit.
Every single button is completely dead except Power - nothing beeps, nothing responds, nothing.
The washer looks frozen but the display is on and the machine might actually be running a cycle just fine.
Cycle keeps going normally but you can't adjust anything, change spin speed, add a rinse, nothing.
You press buttons and there's zero feedback, no click, no beep, just silence.
Can you reset a Lg washer to clear the CL code?
To toggle Child Lock off on WM front-load models: press and hold Spin Speed for 3 seconds until you hear a beep and CL disappears. On WT top-load models: hold the Temp button for 3 seconds. If neither works, look for the button with a padlock icon printed near it and hold that one. No power cycle needed, takes effect immediately.

Frequently Asked Questions
How do I turn off CL on my LG washer?
On most LG front-loaders: hold the Spin Speed button for 3 seconds. On top-loaders: hold the Temp button for 3 seconds. If neither works, scan every button on your panel for a tiny padlock icon printed near it - that's your Child Lock button no matter what else it says. Hold it 3 seconds and wait for the beep. That beep means it worked. Whole thing takes about 10 seconds once you find the right button.
Which buttons activate Child Lock on LG washers?
Depends on the series, which is honestly kind of annoying. WM3700 and WM4000 front-loaders use Spin Speed held 3 seconds. WM5000 and WM8100 series usually have a dedicated button with an actual padlock icon. WT series top-loaders use Temp or Rinse. The fastest approach is just looking at the panel for that small padlock symbol - it's printed in tiny text near the button that controls it. That symbol is your answer regardless of what the button's main label says.
Why does CL keep turning on by itself?
Stuck button, almost every single time. The touchpad membrane underneath the panel wears out and starts sending continuous phantom press signals to the board. When those signals randomly hit the right button combination, CL activates by itself. Press every button firmly and check that each one springs back. If you find one that feels stuck or mushy and doesn't pop up, that's it. New touchpad membrane is usually $40-90 depending on your model. I replaced three of these last month alone, it's a really common failure on LG panels that are a few years old.
Can I run a wash cycle with Child Lock on?
Yes, absolutely. If CL activated mid-cycle the machine just keeps running whatever it was doing. You can't change anything - can't add a rinse, can't adjust spin speed, can't pause it to throw in that sock you forgot. But the cycle will finish completely on its own. Just let it run and clear the CL code after it's done. The only thing that still works while CL is active is the Power button.
Is CL an error code or a feature?
It's a feature, not an error. Nothing is broken. Your washer is 100% fine. CL stands for Child Lock and LG put it there intentionally so kids can't mess with the settings mid-cycle. Probably half the people who contact me about this think their washer just died. It didn't. Took me 30 seconds to clear the last one I got called about. No parts, no repair, no cost. Just a button hold.
Why won't the Child Lock button work on my LG washer?
Usually means you're pressing the wrong button for your specific model. Different LG series use different buttons for Child Lock, which is a real pain. Try holding each button one at a time for 3 seconds and watch for CL to disappear. Also worth checking your owner's manual - Child Lock is listed in the control panel section and they'll tell you exactly which button it is. If you've tried every button and nothing clears it, unplug the washer for 60 seconds and plug it back in. A soft reset occasionally unsticks a weird locked panel state.
