Think of a dishwasher as your very own robot that will clean as well as rinse all your dirty dishes. Put things simply, basically the dishwasher will take in an amount of cold water and then heat this to certain temperatures which are way higher than could be possible for hand washing. The temperatures are typically more than 130ºF.
Remember the dishwasher in actuality does not make use of lots of water, since it does totally fill up. It is just that the water enters via a small basin found at the bottom. Pumps are present to force the water (still at very high temperatures) into these rotating arms which have spray jets. Think of how lawn sprinklers act. The sheer force of the water is what rotates these arms, such that the water as well as the detergent can then reach every corner of the load.
There is a certain programmed cycle after which can either be dried or left to drain dry. Visit home.howstuffworks.com/dishwasher.htm for details on how dishwashers work.
