I use their recommended drying agent and yet this dishwasher doesn't dry dishes like other dishwashers. GE's response to the other reviewer misses what GE's OWN instruction manual says, which is "For proper drying, the dishwasher door must be opened immediately after the Clean light comes on." In other words, yes, you have to be ready to open the dishwasher immediately when clean cycle comes on or else your dishes won't dry.
