A dishwasher includes a tub formed by a plurality of walls defining an interior and an exterior, a first conduit coupled to the tub, a valve coupled to the first conduit, a rack moveable between an engaged horizontal position and a disengaged horizontal position and between an upper vertical position and a lower vertical position, and a second conduit coupled to the rack. A first portion of the second conduit engages the valve when the rack is in the upper vertical position, and a second portion of the second conduit engages the valve when the rack is in the lower vertical position. The valve permits fluid to flow from the first conduit to the second conduit when the rack is in the engaged horizontal position. The valve does not permit fluid to flow from the first conduit to the interior when the rack is in the disengaged horizontal position.

1. A dishwasher comprising: a tub formed by a plurality of walls defining an interior and an exterior;a first conduit coupled to the tub;a valve coupled to the first conduit;a rack moveable between an engaged horizontal position and a disengaged horizontal position and moveable between an upper vertical position and a lower vertical position; and a second conduit coupled to the rack;wherein a first portion of the second conduit is configured to engage the valve when the rack is in the upper vertical position and a second portion of the second conduit is configured to engage the valve when the rack is in the lower vertical position;wherein the valve permits fluid to flow from the first conduit to the second conduit when the rack is in the engaged position, and wherein the valve does not permit fluid to flow from the first conduit to the interior when the rack is in the disengaged position;wherein the valve comprises an outlet and a ball that substantially seals the outlet when the rack is in the disengaged horizontal position; andwherein the second conduit comprises a shroud containing a first projection and a second projection, wherein the shroud is configured to enclose at least a portion of the valve when the rack is in the engaged horizontal position; andwherein the first projection and the second projection are configured to displace the ball out of engagement with the outlet when the rack is in the engaged horizontal position. 2. The dishwasher of claim 1, wherein the first conduit and the valve are located at the exterior of the tub. 3. The dishwasher of claim 1, wherein the valve further comprises an incline that supports the ball. 4. The dishwasher of claim 3, wherein the incline comprises a curved surface. 5. The dishwasher of claim 3, wherein the incline is integrally formed with the first conduit. 6. The dishwasher of claim 1, further comprising: an insert coupled to the second conduit and located at least partially within the shroud;wherein the first projection extends from the insert and the second projection extends from the insert. 7. The dishwasher of claim 6, wherein the insert further comprises a plurality of apertures configured to permit fluid to flow from the first conduit to the second conduit. 8. A fluid supply system for an appliance comprising: a conduit having an outlet; anda spray assembly having an inlet comprising at least a first projection and a second projection;wherein the inlet is configured to engage the outlet at the first projection of the inlet when the spray assembly is in an upper position and at the second projection of the inlet when the spray assembly is in a lower position;wherein the outlet permits fluid to flow from the outlet to the inlet when the inlet engages the outlet; andwherein the outlet does not permit fluid to flow from the outlet when the inlet is disengaged from the outlet. 9. The fluid supply system of claim 8, further comprising: a tub having an exterior; wherein the conduit is located on the exterior of the tub. 10. The fluid supply system of claim 8, wherein the outlet further comprises a ball member and an inclined surface to support the ball member, and wherein one of the first and second projections engages the ball member when the inlet engages the outlet. 11. The fluid supply system of claim 10, wherein the inclined surface is integrally formed with the conduit. 12. The fluid supply system of claim 8, further comprising a second spray member and a third spray member both coupled to the conduit, the spray assembly being located between the second spray member and the third spray member. 13. An appliance comprising: a tub having an interior;a conduit coupled to the tub, the conduit having an outlet and a ball that is moveable between a first position and a second position such that the ball permits a fluid to exit the outlet only when the ball is in the second position; anda spray member for providing the fluid to the interior and having an inlet and being removably coupled with the outlet to receive the fluid from the outlet, the spray member including a first projection and a second projection that selectively interface with the ball such that the ball is in the first position when the inlet is not coupled with the outlet, and the ball is moved to the second position when the inlet is coupled with the outlet. 14. The appliance of claim 13, further comprising: a rack adjustable between at least a first position and a second position and coupled to the spray member; wherein the first projection is configured to interface with the ball when the rack is in the first position and the second projection is configured to interface with the ball when the rack is in the second position. 15. The appliance of claim 13, wherein the spray member includes an insert comprising the first projection and the second projection, the insert further comprising a plurality of apertures configured to permit the fluid to flow from the conduit through the insert and to the spray member. 16. The appliance of claim 13, wherein the conduit is coupled to an inclined surface configured to support the ball. 17. The appliance of claim 13, wherein the conduit is located to the exterior of the tub. 18. A dishwasher comprising: a tub;a wash pump coupled to the tub;a rack moveable between a first horizontal position and a second horizontal position;a spray arm assembly removably coupled to the rack and comprising a spray arm and a first conduit; anda second conduit located at the exterior of the tub that fluidly couples the wash pump to the spray arm assembly when the rack is in the second horizontal position;wherein the first conduit includes a first attachment feature that engages a first tine on a rear side of the rack and a second attachment feature that engages a second tine on the bottom side of the rack; andwherein the first conduit comprises an inlet defining an open cavity and the second conduit comprises an unrestricted port to provide a valveless interface between the first conduit and the second conduit capable of non-discrete engagement positions. 19. The dishwasher of claim 18, wherein the first attachment feature comprises a hook and catch member that provides a snap fit engagement to the first tine, and the second attachment feature comprises a recess that engages the second tine. 20. The dishwasher of claim 18, further comprising a guide member configured to assist in maintaining the spray arm in a generally horizontal orientation during rotation. 21.
