Abstract
A dishwasher has multiple wash zones which are each supplied by a wash liquid supply. An interior tub configured to provide an interior wash chamber for washing dishes is divisible into three wash zones supplied by first, second, and third wash liquid supplies. The third wash zone is supplied by a wash liquid supply that is controllable independently of the other two wash liquid supplies. The third wash liquid supply can be controlled to supply wash liquid to a detergent dispenser or a wall-mounted spray manifold, or shut off separately from the first and second wash liquid supplies.
