I have been fighting an ongoing battle with samsung for a year now. The same repairs have been made multiple times. My only saving grace was the good sense to buy an extended warranty on my SF448AAW/XAA. The steam generator has broken three times. The glass door fractured. The power switch broke and the motherboard on the power switch and the main control board has been replaced. If you have only had the unit 30 days of less run back to where you bought it and give it back quickly. Otherwise buy and extended warranty plan and hold on for a wickedly frustrating ride.
