LG WM-14220FD washing machine - Childlock button issues?

The machine features two buttons to press together to put on the child lock, preventing little fingers from changing the settings. When I do this and 'CL' appears in the display, all buttons EXCEPT the on/off button are protected... My 2 year old daughter keeps pressing this during a cycle and we have to start the wash all over again!!
Is there an electronics reset operation or do we have to waste loads of water and energy over and over...?
