no function is accepted by washer

Hi,

I have lg 6 kg front load washing machine, before it was fine but now no function is accepted by washer, after reading above questions I pressed play/pause button for 5 seconds , than I saw only cotton function is running , in this cotton cycle only wash option is working continuously and not going ahead. How to reset this machine ?

I read all questions and didn't got any proper answer. Plz help me to get rid of this problem
