1. A dishwasher for cleaning utensils according to at least one automatic cycle of operation, comprising: a tub at least partially defining a treating chamber for receiving utensils for cleaning;a spray system for spraying liquid in the treating chamber;a rack located within the treating chamber and having two laterally-spaced upwardly-extending rows of rack tines defining a passage in between;a carriage located within the passage, wherein the carriage comprises two laterally spaced carriage rails;two laterally-spaced upwardly-extending rows of carriage tines extending upwardly from the carriage rails parallel to the rows of rack tines;a coupler slidably mounting the carriage to the rack within the passage for slidable movement of the carriage within the passage relative to the rows of rack tines along a sliding range of motion, and applying a sliding resistance force to the carriage to hold the carriage in a sliding position along the sliding range of motion;a first continuous wire having a bight portion spanning and connected to the two carriage rails and legs extending upwardly on opposite sides of the bight portion forming a pair of the carriage tines; anda second continuous wire having a bight portion spanning and connected to the two carriage rails and separated from the first continuous wire and legs extending upwardly on opposite sides of the bight portion of the second continuous wire forming a second pair of the carriage tines;wherein the coupler slidably receives one of the carriage rails between the first and second continuous wires, and the coupler contacts the first and second continuous wires as the carriage is slid through the sliding range of motion to limit the sliding range of motion to a sliding distance between the first and second continuous wires. 2. The dishwasher of claim 1 wherein first and second rack tines are spaced along the passage by a first distance substantially the same as a second distance between the first and second continuous wires. 3. A dishwasher for cleaning utensils according to at least one automatic cycle of operation, comprising: a tub at least partially defining a treating chamber for receiving utensils for cleaning;a spray system for spraying liquid in the treating chamber;a rack located within the treating chamber and having two laterally-spaced upwardly-extending rows of rack tines defining a passage in between;a carriage located within the passage, wherein the carriage comprises two laterally-spaced carriage rails;two laterally-spaced upwardly-extending rows of carriage tines extending upwardly from the carriage rails parallel to the rows of rack tines;a coupler slidably mounting the carriage to the rack within the passage for slidable movement of the carriage within the passage relative to the rows of rack tines along a sliding range of motion, and applying a sliding resistance force to the carriage to hold the carriage in a sliding position along the sliding range of motion; anda first continuous wire having a bight portion spanning and connected to the two carriage rails and legs extending upwardly on opposite sides of the bight portion forming a pair of the carriage tines;wherein the coupler comprises a spring clip snapped onto the bight portion. 4. The dishwasher of claim 3 wherein one of a first of the carriage tines and the coupler comprises a detent to fix the location of the carriage tines relative to the rack tines. 5. The dishwasher of claim 3 wherein the coupler comprises a passage slidably receiving one of the carriage rails. 6. The dishwasher of claim 5 wherein the rack comprises a rack rail from which one of the two rows of rack tines extend, and the coupler comprises a hook coupling to the rack rail. 7. The dishwasher of claim 3 wherein the bight portion has an upwardly extending portion. 8. A dishwasher for cleaning utensils according to at least one automatic cycle of operation, comprising: a tub at least partially defining a treating chamber for receiving utensils for cleaning;a spray system for spraying liquid in the treating chamber;a rack located within the treating chamber and having two laterally-spaced upwardly-extending rows of rack tines defining a passage in between and two laterally-spaced rack rails from which respective ones of the two rows of rack tines extend upwardly;a carriage located within the passage and comprising two laterally-spaced carriage rails;two laterally-spaced upwardly-extending rows of carriage tines extending upwardly from the carriage rails parallel to the rows of rack tines;a coupler slidably mounting the carriage to the rack within the passage for slidable movement of the carriage within the passage relative to the rows of rack tines along a sliding range of motion, and applying a sliding resistance force to the carriage to hold the carriage in a sliding position along the sliding range of motion;wherein the coupler fixedly mounts to one of the rack rails and slidably mounts to one of the carriage rails to slidably mount the carriage to the rack;wherein the coupler comprises a force applicator applying the sliding resistance force to the one of the carriage rails and the force applicator is a spring finger abutting the one of the carriage rails to apply a contact force on the one of the carriage rails lateral to the sliding range of motion to form the sliding resistance force; andwherein the coupler comprises a spring clip snapped onto the carriage. 9. The dishwasher of claim 8 wherein the coupler comprises a passage slidably receiving the one of carriage rails. 10. The dishwasher of claim 9 wherein the coupler comprises a hook coupling to the rack. 11. The dishwasher of claim 8 wherein the two rows of carriage tines have a same or greater spacing than the two rows of rack tines.
