A:Answer Hi Sherry29- Thanks for choosing GE Model GFW650SSNWW! During the cycle, the basket spins and creates air flow that pulls fresh air into the washer through the vent in the door while the tub quietly spins in 15-minute increments on and off until the gasket and washer tub are dry (up to 8 hours) for best performance. The UltraFresh Vent System with OdorBlock™ feature may be cancelled at any time by pressing the Power pad, turning the cycle knob, or pressing ULTRAFRESH VENT pad. We're glad to have you in the family. If you have any additional questions, don’t hesitate to ask. We are also happy to help at GEAppliances.com! Sue
