From the looks of the picture, it was easier to pour Sta-Puf in the rinse dispenser of the Norge than into the Hotpoint's softener dispenser reservoir. The two liquid bins were flip over type, sort of a cylinder with an opening in a quarter of it. Any dispenser on a washer needs to be flushed between uses. If you or the machine keep the dispenser clean, it will keep working. If you don't, you will have problems with its use. The system was a bit of overkill in that detergent, whether liquid or powder, did not need a dispenser especially when you have a filter pan into which the powder detergent and powder bleach could be preloaded and, indeed, the next iteration of the Dispensomat was a two chambered affair for liquid bleach and fabric softener. As for the need for a dispenser for liquid detergent, part of the sales campaign was that it could be poured onto areas of fabrics that needed pretreating. Norge's overflow rinse did provide a way to use both Calgon and fabric softener in the same rinse with the Calgon added at the start and the softener added at the end, but the use of Calgon declined as detergent technology improved and the price of Calgon increased.
