First try unplugging the machine for a few minutes and then retry a cycle. If you still get the LE error:

The Hall sensor (part number 6501KW2001A) has failed. The hall sensor is rather easy to replace, and is covered by a seven year part warranty (in the US). Take the back cover off. Take the big nut off and remove the motor rotor. Remove the bolts holding the motor windings. Remove the electric plug on the sensor and unclip it from the motor winding. Snap new sensor on and reassemble. Usually takes under a half hour. On a difficulty scale of 1 - 10, it might rate a 4. This should be a Fix-Ya for your machine, and at basically no cost!

Depending on how many clothes are in the washer you may a unbalance error

SOURCE: My washer is marking LE.What does that mean?

This is a motor overload. Could be too many items in the barrel. I have had this code in the past and took some items out and it went away. I still think there is an underlying issue with the hall sensor or the motor altogether.
