How do I lock the control panel to prevent accidental operation?
Touch the LOCK pad twice within 3 seconds and all pads become inoperative. The light above the LOCK pad will turn on. To unlock the dishwasher after it has been locked, touch the LOCK pad twice within 3 seconds and the light will turn off.
