Product review (4 stars): Works, but not an exact fit.
Worked well on 2nd Samsung washer.  Resolved the pump issue.  Lay your washer on its side and go through the bottom vice disassembling the front.  Prior to starting work, duct tape off the edges of the opening or you WILL cut yourself on the sharp edges.  Pump can easily be changed out in an hour.

Note that this will mate up well, but cover piece will not bolt on.  I tie strapped the metal shield cover in place to protect the motor.  You will still need to pull on the entire hose and elbow assembly to ensure it is clean.  Note that the elbow assembly at the bottom of the washer tube is probably the source of the blockage that caused the pump to wear out.  It is the perfect size to trap a quarter.  Look at " Supco LP1700A Washer Pump" to see how much you need to remove to ensure you got all of the crap out of the suction.
