LG Dishwasher CL Error Code: What It Means & What to Check
Q: My LG dishwasher is showing CL. What does that mean?
A: On many LG dishwashers, CL usually means Child Lock / Control Lock is active. This is typically not a failed part—it’s a feature that locks the controls to prevent accidental button presses.
This guide covers what CL means, how to turn it off, and when to call our friendly technicians in yellow if the controls still won’t respond.
What You May Notice
- CL appears on the display
- Buttons do not respond normally
- Cycle will not start when you press Start
- Only certain buttons work (or none seem to work)
Safety First
- CL is usually a settings/controls issue, not an electrical failure.
- Do not force buttons or pry on the control panel.
- If you plan to power reset the unit, use the breaker safely.
Quick Checks You Can Try First
1) Disable Child Lock / Control Lock
Use the correct button combination for your LG dishwasher model to turn off Child Lock / Control Lock. The exact button names can vary by model (for example, a two-button press-and-hold combination).
2) Press and Hold Long Enough
Many LG dishwashers require holding the control-lock combo for several seconds. If it does not clear right away, try again and hold the buttons steadily.
3) Check the Control Panel Labels
Look near the buttons for a small label that says Control Lock, Child Lock, or shows a lock icon with instructions like “Press and hold 3 sec.”
4) Power Reset at the Breaker (If Needed)
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.
Common Causes (What CL Usually Points To)
- Child Lock / Control Lock was turned on intentionally or accidentally
- Incorrect unlock button combo used for that model
- Control panel input issue (less common) if lock will not disengage
Likely Parts a Technician May Check
- None in most cases (CL is usually just a control setting)
- Control panel / user interface (if buttons do not respond)
- Main control board (less common, if the panel remains locked incorrectly)

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 “Press and hold 3 sec.” instructions.
Why won’t the buttons work when CL is showing?
Child Lock / 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 combo 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.
