How do I lock the control panel to prevent accidental use by children?

Touch the LOCK pad twice within 3 seconds to lock all the control pads, making them inoperative so children cannot accidentally start the dishwasher. You can also lock the controls after starting a cycle or selecting DELAY START to prevent interruption. To unlock the dishwasher, touch the LOCK pad twice within 3 seconds again, and the light above the LOCK pad will turn off. (Page 5)
