Your welcome--but I am confused.
Please enlighten us as to what you found at fault.
An "LE" error can be:
Hole in hose at WATER LEVEL SENSOR
Hose clogged with debris
Hose disconnected from WATER LEVEL SENSOR
Failed WATER LEVEL SENSOR
Plug disconnected at WATER LEVEL SENSOR
Failed MAIN BOARD
Since water was observed entering the washer--this rules out a problem with the WATER LEVEL SENSOR--unless it overfilled.
The drain strainer was cleaned out (although no heavy blockage was present)
Very very very rarely does a heavy load of laundry trigger an error.
In fact--I've never seen this condition occur--ever.
Naturally--I'm curious as to what you've discovered to be the problem.
FWIW--I've had about a half dozen Samsung washer warranty calls on washers that appear to work normally EXCEPT the high speed spin cycle was not always functioning.
Samsung sent a bulletin which indicated that there was a problem with the MAIN BOARD on the WF218ANW
In *most* cases the intermittent spin condition was found on washers located in areas of the home that was cold--usually in the basement. Two or three were not--but cold water wash & rinse cycles were used almost exclusively.
Since then--I had other models exhibiting the same symptoms (WF209/WF328) which leads me to think that perhaps other models will added to the list in the Technical Service Bulletin.
Time will tell...
