What does this code mean?

I have an LG Turbo drum, fuzzy logic, 6.5kg washing machine. It regularly comes up with the code Le or 1e. What does it mean. After Ive put the washing on, I go away and come back and its stopped on this code. It goes again after I press the start button but it drags out the time it takes to do the washing especially when I think its done only to find its been sitting for an hour on this code.
