LG Dishwasher Error CL: Child Lock Active

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

The child safety lock is engaged. All control panel buttons are disabled to prevent accidental operation or cycle changes. This is not a fault — it is an intentional safety mode.

Severity

Low - usually safe to check with basic user-accessible cleaning or inspection on the LG dishwasher.

Can you fix it yourself?

Yes — DIY-safe

Most likely cause

Child lock was deliberately activated by the user

Estimated time for safe first checks: 1–2 min.

Step-by-Step DIY Fix Guide

  1. SAFETY: No electrical hazard — CL is a safety mode indicator.
  2. Locate the Child Lock button on your model — it is typically labeled with a padlock icon.
  3. Press and hold the Child Lock button for 3 seconds until CL disappears from the display.
  4. On some LG models, Child Lock is activated and deactivated by pressing and holding two buttons simultaneously — refer to your owner's manual for the exact combination on your model.
  5. If the button sequence does not work, disconnect power for 60 seconds, then restore — the child lock will reset.

If the door warning comes back

  • If the door closes normally but the warning keeps returning, the latch or switch path becomes more likely than a simple alignment issue.
  • If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
  • CL cannot be deactivated by the button sequence or a 60-second power reset

What This Error Means

Error CL on your LG dishwasher means: The child safety lock is engaged. All control panel buttons are disabled to prevent accidental operation or cycle changes. This is not a fault — it is an intentional safety mode. The dishwasher's self-diagnostic system has detected this condition and paused the current cycle.

The most frequent cause is child lock was deliberately activated by the user. Work through the causes and fix steps below in order — most LG dishwasher errors are resolved without a service call.

Error CL is DIY-safe. No tools are required and the fix typically takes under 10 minutes. Follow all steps in sequence.

This is a mode indicator, not a hardware fault. The dishwasher is operating exactly as designed — the display is informational. Follow the steps above to return the machine to normal operating mode.
