What detergent is recommended for the GE GSD5610 dishwasher?

Only detergent specifically made for use in dishwashers should be used — Cascade® Automatic Dishwashing Detergent has been approved for use in all GE dishwashers. Do not use regular dish soap, as it will cause sudsing. Detergent should be kept fresh and dry, and should not be placed in the dispenser until you are ready to wash dishes. (Page 13)
