If it is a Deluxe model without the dual detergent dispensers, you can always open the door and add a tablespoon of detergent to the first of the 4 rinses. If you have a lot of plates, like after a big buffet banquet, it holds a lot of them, in two rows front to back down both sides of the lower rack with room down the middle for small plates if you tilt the dinner plates slightly forward on the outside edges of the rack. I used to pack one of these nightly in the late 60s at my second family's house.
