How do I lock the controls to prevent unintended changes during a wash cycle?

Press and hold the CONTROLS LOCK/UNLOCK button for 3 seconds; the status light next to the button will glow to confirm the controls are locked. When controls are locked, all buttons are disabled except for PAUSE/CANCEL and START. To unlock, press and hold CONTROLS LOCK/UNLOCK again for 3 seconds until the status light turns off. (Page 14)
