Your LG dishwasher has many different features and cycles, but the ones you will likely use the most are your Normal, Quick and Dry, and Quick cycles. They all serve a different purpose, but are equally helpful for doing standard loads.
The Normal cycle is best suited for normally soiled, everyday loads. The Quick and Dry cycle is a shortened, 77 minute cycle best suited for recently used or lightly soiled dishes. It also includes a quick dry cycle at the end. The Quick cycle is a shorter, 33 minute cycle that is best for recently used or lightly soiled dishes, without drying. See these cycles in action.
