How to Fix the LG Dishwasher CL Code: Causes, Fixes & Reset Guide
If your LG dishwasher suddenly shows the CL code, you’re not alone. Many homeowners see this message and assume something is wrong with the appliance. In reality, CL is not an error at all. It simply indicates that the Child Lock feature is activated, preventing the control panel from responding until the lock is turned off.
This guide from Appliance Local explains what the CL code means, how to disable it, and what to do if it won’t clear—even after trying the usual reset steps.
What the CL Code Means on an LG Dishwasher
The CL indicator appears whenever the dishwasher’s Child Lock safety function is turned on. This feature stops kids—or anyone— from accidentally pressing buttons, changing cycles, or interrupting a wash. Once enabled, the control panel becomes completely unresponsive, and you won’t be able to start, stop, or adjust any options until the lock is deactivated.
Although it’s helpful for families, it can be frustrating when activated by mistake. If your dishwasher buttons are not working and you see CL on the display, the Child Lock is active.
How to Turn Off the Child Lock on an LG Dishwasher
Since the CL code is not a malfunction, turning it off is usually simple. You can deactivate the feature yourself in just a few seconds.
Locate the Child Lock Button or Lock Icon
Depending on your LG model, the Child Lock symbol may appear as “CL,” a padlock icon, or a dedicated button.
On top-control dishwashers, the lock is often connected to the Rinse, Half Load, or Heated Dry button.
On front-control models, you’ll typically find it toward the right side of the panel, sometimes paired with the Dry or Extra Dry option.
Press and Hold to Disable CL Mode
Once you find the correct button, press and hold it for 3–5 seconds. The CL indicator should disappear or the lights will blink to show the lock has been disabled. Some models may also beep to confirm the feature is turned off.
Test the Dishwasher
Try selecting a cycle or pressing a few buttons to confirm the controls are working again. If everything responds normally, the Child Lock has been successfully turned off.
If your dishwasher still won’t unlock, additional troubleshooting may be needed.
What to Do If the LG Dishwasher CL Code Won’t Turn Off
If pressing and holding the Child Lock button doesn’t clear the CL code, you may be dealing with a deeper issue such as a stuck button, internal fault, or control board problem. Here’s what you can try next:
Perform a Power Reset
A simple reset often fixes temporary glitches.
Turn off the dishwasher, unplug it from the outlet, and wait 2–5 minutes.
This allows the control board to discharge and reset. Plug the appliance back in and check whether the control panel works normally.
Check for Stuck or Unresponsive Buttons
Moisture, dirt, internal wear, or debris behind the keypad may cause the Child Lock button to stop responding. Gently press around the controls to see if any buttons feel stuck or unresponsive.
Check Warranty or Contact Manufacturer Support
If the dishwasher is still under warranty, it’s a good idea to contact LG for assistance. If not, a professional appliance repair technician can diagnose issues with the control panel, wiring, or touchpad.
When to Call a Professional Dishwasher Technician
While the CL code is generally easy to remove, other issues may require expert attention. You should schedule a professional repair if you notice:
Cleaning or washing performance problems
Grinding, rattling, or unusual noises
Water not draining
Leaks or moisture around the unit
Recurring error codes
Control panel not responding
Child Lock activating repeatedly without reason
Professional technicians can diagnose electrical, mechanical, or internal faults that are not visible to homeowners.
