The 'LE' error message indicates the control board has detected that the motor is either not turning, or has locked up for some reason. Monitoring the motor is the job of the hall effect sensor board which constantly determines the direction and speed of the motor and feeds that information back to the control board. If there is a problem between what the motor should be doing and what the hall effect sensor says the motor is doing, the 'LE' will be displayed and the cycle will be stopped.
1) in my experience, sometimes this proves to be intermitent, and upon unplugging and waiting for 5 minutes does not seem to resurface again...
2)Motor lock can be caused by several things from a loose connector, to a bad motor, or even the hall effect sensor failing or dislodging from it's mount.
this could prove to be very challenging to somebody who does not know what they are working with, i suggest if the problem is not intermitent, call a tech.. hope this helps.
