I've managed to find Samsung washer error codes - see
http://ars.samsung.com/customer/usa/jsp/faqs/faqs_view_us.jsp?AT_ID=84289&PROD_ID=901&PG_ID=-1&PROD_SUB_ID=0
For LE error the samsung list says:-
Natural drain/Water leak error
Check that the level of the drain hose is not lower than the base of the W/M, check for water on the floor? If no trace of water switch off the power/reconnect and try again
If leak found and from W/M or error code persists a service call is adv
