LG dishwasher showing CL?
What does the LG dishwasher CL error code mean?
On many LG dishwashers, CL usually means Child Lock or Control Lock is active. This is typically not a failed part. It is a feature that locks the controls to prevent accidental button presses.
If your LG dishwasher shows CL, the first step is to turn off the control lock using the correct button combination for your model. If the dishwasher has power but the buttons will not respond, the issue may still be a locked control setting. If the dishwasher has other symptoms, such as stopping mid-cycle or not starting after CL is cleared, compare with Why Is My Dishwasher Stopping Mid-Cycle? or visit the Dishwasher Help Center.
What You May Notice
- CL appears on the display
- Buttons do not respond normally
- The cycle will not start when you press Start
- Only certain buttons work, or none seem to work
- The dishwasher appears locked even though it still has power
- The control panel responds only after holding a button combination
Safety First
- CL is usually a settings or controls issue, not an electrical failure.
- Do not force buttons or pry on the control panel.
- If you plan to power reset the dishwasher, use the breaker safely.
- Do not remove the control panel or access wiring unless you are trained to do so.
- Call for service if the control panel remains locked, blank, or unresponsive after safe checks.
Quick Checks You Can Try First
```1) Disable Child Lock or Control Lock
Use the correct button combination for your LG dishwasher model to turn off Child Lock or Control Lock. The exact button names can vary by model. Many models use a press-and-hold combination rather than a quick tap.
2) Press and Hold Long Enough
Many LG dishwashers require holding the control-lock combination for several seconds. If it does not clear right away, try again and hold the buttons steadily. Look for a small lock icon, Control Lock, or Child Lock label near the buttons.
3) Check the Control Panel Labels
Look near the buttons for instructions like Press and hold 3 sec. The unlock instruction may be printed under a button or shared between two buttons. If the panel has power but another control issue is happening, the symptom may overlap with a broader dishwasher control problem.
4) Power Reset at the Breaker
If the display stays stuck on CL or the panel is unresponsive, turn power off at the breaker for about 5 minutes, then restore power and try disabling the lock again. If the dishwasher still will not respond after CL is cleared, you may also want to review Why Is My Dishwasher Door Not Latching or Won’t Close?, because some models will not start if the door latch is not confirmed.
```Common Causes: What CL Usually Points To
```Child Lock or Control Lock Was Turned On
CL is most often caused by Child Lock or Control Lock being turned on intentionally or accidentally. This can happen when buttons are held too long, when cleaning the control panel, or when someone accidentally activates the lock feature.
Incorrect Unlock Button Combination
LG dishwasher models do not all use the exact same unlock command. If the wrong button combination is used, CL may stay on even though the dishwasher is working normally.
Button Not Held Long Enough
Some control-lock features require a steady press-and-hold action for several seconds. A quick press may not clear the lock.
Control Panel Input Issue
Less commonly, the control panel or user interface may not register the button command. If the buttons do not respond after a breaker reset and the correct unlock combination, the user interface may need diagnosis.
Main Control Issue
A main control board issue is less common for CL alone. It becomes more likely if the dishwasher also shows other symptoms, such as random shutdowns, unresponsive buttons, repeated error codes, or cycle problems.
```What Beacon Usually Checks
When our friendly technicians in yellow diagnose an LG dishwasher that stays on CL or will not respond, we first confirm whether this is a normal lock setting or an actual control issue.
```- Control-lock setting: whether Child Lock or Control Lock is active
- Button response: whether the panel recognizes the unlock command
- Door latch behavior: whether the dishwasher recognizes the door as closed
- Power reset response: whether the display and controls recover after a safe reset
- User interface: whether the control panel is responding correctly
- Main control clues: whether there are other symptoms beyond CL
- Related error codes: whether the dishwasher is showing another code after the lock is cleared
If CL is the only thing on the display, the fix is usually simple. If another LG dishwasher code appears after the controls unlock, the next step may be different. For broader code help, visit the Appliance Error Code Help Center.
```When to Call Beacon
Call Beacon if you have tried the correct control-lock button combination and a breaker reset, but the dishwasher still stays on CL or the buttons will not respond. At that point, the issue may involve the control panel, user interface, door latch signal, or main control.

Frequently Asked Questions
```Does CL mean my LG dishwasher is broken?
Usually no. CL typically means Child Lock or Control Lock is active, which is a normal feature and not a part failure.
How do I turn off CL on my LG dishwasher?
Use the control-lock button combination for your specific model, often a press-and-hold combo. Check the control panel labels for a lock icon or instructions such as “Press and hold 3 sec.”
Why won’t the buttons work when CL is showing?
Child Lock or Control Lock disables or limits button input to prevent accidental changes while the feature is active.
Should I reset power if CL will not turn off?
Yes. A breaker reset for about 5 minutes is a reasonable homeowner-safe step if the panel seems stuck. After restoring power, try the correct unlock combination again.
What parts usually fail when CL is displayed?
Usually none. CL is generally a locked-controls setting, not a repair code. If it will not clear, a technician may check the user interface or control board.
When should I call for service?
Call for service if CL stays on after using the correct button combination and a power reset, or if the control panel is unresponsive.
