After discovering the cause of the leak was horrific engineering on Samsung's part. I ordered the nozzle connector (which was the failed part) and the check valve ball.
Repairs were done in short order, and the machine was up and running again. So with the cost of the parts (crazy amounts for shipping), over $300 for a new floor (as the other was totally ruined by the flood of water from the machine) and three days of my time to reconstruct the laundry room, I'd say all went well.
