How do I unlock CL on LG Inverter Direct Drive True Balance Model Number WM3900HWA ?

Hi @crbc Turn on the power to the machine and then press and hold the Rinse + Spin buttons (both together) for 3 seconds to either activate or deactivate the Control Lock feature.

Hi @Barb Wandsnider Press and hold the soil level button for 3 seconds during the wash cycle to disable the child lock. Here’s the section from the user manual that explains how to enable and disable the feature.

None of the above worked, probably because my panel is different. Then I noticed on my LG the Half Load and Energy Saver had an note below them: Control Lock. I pressed both simultaneously and the frustrating CL was cleared.

This worked on my LG model, which has a similar control panel to yours: For front-loading washer dryer combo “Inverter Direct Drive True Balance” LG model #WM3499H*A:

  1. Once LG machine is powered ON:
  2. Go to the right touch-screen panel, press and hold “Pre-wash + Delay wash” buttons simultaneously for 3-5 seconds. This will turn OFF the CL (control lock/child lock). You’ll hear a little jingle when the function is processed.
  3. Similarly, pressing this combo simultaneously again for 3-5seconds will turn back ON the CL . Hope this helps!

Press and hold the CHILD LOCK button for 3 seconds
