A completed wash does not automatically disable Child Lock. Identify the printed lock legend and the exact panel’s hold action. For a WM4000HWA, use the model-specific Rinse+Spin comparison linked below; do not apply that gesture universally.
Selected LG washers code family. Confirm the exact model and displayed characters; similar codes on other appliances are not interchangeable.
Wait for motion to stop and the door or lid to unlock. Water may be hot. Isolate power and follow the exact manual before any user filter maintenance. Never open a filter against a full drum, force a lock or bypass an interlock.
Compare the behavior
Child Lock can remain enabled after a cycle, so a completed load does not prove the setting is off. The model’s labeled release action is more useful than power interruption or repeated random button presses. If the correct action does not clear CL, preserve a photograph of the panel and the exact model for support. That is a control-response problem to investigate, not proof that a new board is needed.
| Observed state | Interpretation / next step |
|---|---|
| What the code narrows down | A completed wash does not automatically disable Child Lock. Identify the printed lock legend and the exact panel’s hold action. For a WM4000HWA, use the model-specific Rinse+Spin comparison linked below; do not apply that gesture universally. |
| What it does not prove | A display code is not a verified failed-part or compatibility diagnosis. |
Code-specific checks
Locate the labeled control
Find the Child Lock text or lock symbol on the actual panel. The linked LG guide shows several different arrangements, so identify yours before pressing buttons.
Follow the model’s hold instruction
Use the manual’s specified button or combination and hold time. A completed cycle does not necessarily disable Child Lock.
Recheck and seek help if needed
Confirm the indication clears and normal controls return. If the documented action does not respond, contact LG with the model and panel photograph rather than forcing the buttons.
If the warning returns
CL clears → normal controls restored
Cannot identify the control → consult model manual
Correct procedure unresponsive → manufacturer support.
When to stop and get help
Only carry out maintenance permitted in your model’s manual. For service, note the full model number and suffix, displayed code, selected cycle and what happened during the checks. Leave internal wiring, gas components, pumps and safety devices to a qualified professional. A symptom alone does not identify a failed part.
Does unplugging always remove Child Lock?
Do not rely on that. Follow the labeled control and model-specific release instructions.
