What to Check First
- A lock icon lights up on the display, or "CL" appears on the screen.
- All cycle and option buttons are disabled.
- If your LG dishwasher displays "CL" and the buttons are unresponsive, the Child Lock feature is active. This safety feature prevents unintended use. To disable Child Lock, make sure the dishwasher is turned on, then press and hold the Child Lock button for 3 seconds.
- Child Lock is a safety feature designed to prevent accidental operation by children. When active.
- Child Lock remains active even after a wash cycle ends or the dishwasher is turned off. Therefore, when you turn the dishwasher back on, the buttons will still be unresponsive.
- 1. Press the [Power] button to turn on the dishwasher. 2. Press and hold the [Child Lock] button on the control panel for 3 seconds. 3. Once the "CL" indicator or lock icon disappears from the display, select your desired cycle.
- * Note: Child Lock remains active even if you turn the dishwasher off and on again after a cycle ends. If the buttons are unresponsive after powering on, disable Child Lock before use. Please note that this is not a malfunction.
