LG Washer Code LoC — Control Lock Active
What this means
The LoC indicator on LG washing machines means the Control Lock feature is active. This is not an error code but a deliberate safety feature that disables all control panel buttons to prevent accidental changes to settings or cycle interruptions. This is especially useful in households with children or when the washer is located in a shared space. When LoC is displayed, pressing any button on the control panel will have no effect. The washer must be unlocked before a new cycle can be started or settings can be changed. On LG WashTower and TWINWash systems, each unit (washer and dryer) has its own independent control lock.
Alternate codes: Loc, LOC
Step-by-step fix
2 stepsDeactivate the control lock
Press and hold the button or button combination designated for Control Lock for 3 seconds. The LoC indicator will disappear and full control panel functionality will be restored. The lock button varies by model — look for 'CL' or a lock icon printed near a button on your control panel.
Common lock button combinations include: holding the TEMP button for 3 seconds, or pressing and holding two specific buttons simultaneously. Check your model's user manual for the exact method.
Power-cycle if lock will not disengage
If the LoC indicator will not clear after holding the correct button, unplug the washer for 1 minute, then plug it back in. Try the unlock procedure again after the washer powers on.
Make sure you are pressing and holding the correct button — some models require holding a button combination, not just a single button.
When to call a professional
Not necessary. LoC is a normal safety feature. If the control lock cannot be deactivated even after a power cycle and correct button procedure, the control panel or main board may have a fault.
