The factory default setting for the Normal Cycle should be Warm/Cold, with Hot/Cold and Cold/Cold being selectable options. If your WF448 appears to be defaulting to Cold/Cold, I would suggest checking to make sure the My Cycle feature is not activated. If selected, My Cycle would override the factory default. If this feature is not activated and your washer's defaults do not match the chart, then your machine may require service to correct this. You could either submit an online service request through the link below, or call 800-SAMSUNG to speak with any agent who would be happy to assist you.
