Hello there! Thank you for reaching out. The LE error code on your WM3400CW washer generally indicates a motor issue or a problem with the motor's wiring or connections. Since the washer is not starting and troubleshooting steps haven’t resolved the issue, there may be a more significant problem with the motor or another internal component. Please try unplugging the washer for about 10 minutes to reset the control board, ensure the door is fully closed and the lock mechanism is working, and check the wiring connections to the motor and control board for any visible issues. If the problem persists, we recommend contacting LG customer service or a professional technician for a thorough diagnosis and repair. For additional support, you can also send us a private message on Social Media @LGUSupport. —Avril
