UPDATE: My customer just informed me that they have a extended warranty on the washer. So they had the warranty service company come out and the service tech told her he could not find anything wrong with the washer. He said she was using too much detergent! After that she washed 3 loads OK and the LF error code came back again. Her husband thinks it's a faulty main control board. Her extended warranty states that if the washer cannot be repaired they will replace it with a new unit so I guess I'm out of the loop and most likely will never hear back from her to find out what was wrong or it the washer was replaced. What will be - will be!!!
