Fix for LE error code?

On my LG wm1814cw front load wahser, I got LE error code and the drum doesn't spin, i think due to exessive suds. Does anybody know how to reset the control panel. I have washed with no detergent just to clean and also used vinegar. I have tried unplugging many times for more than 30 minutes and it still doesn't reset. I am thinking the motor is fine and its just reseting of LE error code. Is there a fix to it.
