What should I do before washing my first load of laundry in the WAW285H2?

Before your first load, run a Drum Clean cycle with no laundry to clean the system. First add 1 to 2 tablespoons of detergent to the main-wash chamber II, then run the Drum Clean cycle and wait for it to finish. This is necessary because the washer was tested at the factory, which may have left a small amount of residual water in the tub and drainage system. (Page 23)
