For the LE error code I am sending you a link that covers the same symptom. Please click on the link below for that information.
What does the error message "LE" mean on my LG washing machine?
For the unit being dead, First,
disconnect power before attempting access
. I recommend removing the top panel & inspecting the harness plug connectors on the control. If everything looks good and you have confirmed the power is working going to the washer I recommend calling for service. If you have a meter & feel comfortable checking voltage & decide to perform the diagnosis, please get back with us on this.
