Richie, I remember reading that too about placing the detergent at the bottom of the tub alongside the agitator. But I didn't follow those instructions, I thought going down the agitator column was far more fun and it always worked so well. The only reason I can think of those instructions were like that is on the small water level, not much water churcns thought the base of the column. In fact, I don't believe it's high enough for the filter to actually come in contact with much water at all.
