Splendide washer legends

Saw the topic on washer/dryer combos. We haven't used our Splendide 2000 for years--the wife thought it took way too long to dry. Thought I'd try it again, but couldn't find the manual, and the trays for detergent etc. are just labeled A, B, and C. What goes where? I would think detergent in A, but???? Can anyone help with the legends?
