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.

a wash tub defining a wash chamber for receiving utensils to be washed and having an open face through which access is provided to the wash chamber;
a door selectively moveable between open and closed positions for selectively closing the open face when the door is in the closed position; and a wash liquid delivery system comprising first, second, and third wash liquid supplies that supply wash liquid to the wash chamber wherein the delivery of wash liquid to the third wash liquid supply is selectively independent of the delivery of wash liquid to the first and second wash liquid supplies.
a wash tub defining a wash chamber for receiving utensils to be washed and having an open face through which access is provided to the wash chamber;
a door selectively moveable between open and closed positions for selectively closing the open face when the door is in the closed position; and a wash liquid delivery system comprising first, second, and third wash liquid supplies that supply wash liquid to the wash chamber wherein the delivery of wash liquid to the third wash liquid supply is selectively independent of the delivery of wash liquid to the first and second wash liquid supplies.
2. An automatic dishwasher according to claim 1, wherein the first and second wash liquid supplies are fluidly interconnected.
3. An automatic dishwasher according to claim 1, wherein the wash liquid delivery system further comprises a valve for selectively controlling the delivery of wash liquid to the third wash liquid supply.

5. An automatic dishwasher according to claim 4, wherein the wash zones are vertically demarcated.
6. An automatic dishwasher according to claim 5, wherein the third wash liquid supply supplies wash liquid to the uppermost wash zone.
7. An automatic dishwasher according to claim 3, and further comprising upper and lower baskets for holding utensils, wherein the uppermost wash zone supplies wash liquid to an upper portion of the upper basket.
8. An automatic dishwasher according to claim 3, wherein the third wash liquid supply comprises a spray arm assembly for directing a spray of wash liquid into the wash chamber.
9. An automatic dishwasher according to claim 8, wherein the third wash liquid supply further comprises an auxiliary spray arm assembly wherein the valve selectively controls the flow of wash liquid to the spray arm assembly and the auxiliary spray arm assembly.

15. An automatic dishwasher according to claim 14, wherein one of the first and second wash liquid supplies comprises at least one wall-mounted spray manifold and the delivery tube of the auxiliary wash aid dispenser is fluidly connected to the at least one spray manifold such that the wash liquid from the wash aid dispenser is dispensed through the spray manifold.
16. An automatic dishwasher according to claim 3, wherein operation of the valve will shut off the third wash liquid supply from the first and second wash liquid supplies.
17. An automatic dishwasher according to claim 1, wherein the first wash liquid supply comprises a spray arm assembly located in a lower portion of the wash chamber, the second wash liquid supply comprises a second spray arm assembly located in a middle portion of the wash chamber, and the third wash liquid supply comprises a third spray arm assembly located in an upper portion of the wash chamber and wash liquid supply to the third spray arm assembly is controlled selectively independent of the first and second spray arm assemblies.
