Hi Bee,
We understand how frustrating it can be when results and expectations don't quite meet. We are here to help you with your Samsung washing machine model.
I have shared a Samsung link below that will help with your experience. The link has four major steps. Each step has sub-steps to walk you through. The link also has an embedded video which we recommend watching in full. In addition, in step number two, two hyperlinks will help as well (laundry load size & washer cycles, settings, and features).
