I have a LG model # WD1460FHD
Cl means child lock, push and hold wash and rinse button together.
There is a story to this , two years ago same thing happened, I contracted Paul Maters electrical from Noosa QLD,Australia  to fix, he replaced
 the mother board and charged a heap. This
 time I was going to throw the machine out as it is the fourth time i have had a problem with it.
This time I went onto internet found this site and fixed the problem, at no cost.
Boy was i screwed over by the appliance repair guys.
