A latch assembly for a dishwasher door having a bolt secured to the door. The bolt has a catch including a ramp surface facing toward the tub. An actuator is slidably connected to the bolt. A switch is secured to the bolt such that movement of the actuator may selectively close the switch. A handle is moveably mounted to the bolt in a position for access from the front surface of the door. A strike plate is connected to the tub and includes a latching portion extending toward the door. The strike plate flexes vertically to deflect up over the latch when the door moves to the closed position. The strike plate may be released from the latch by moving the handle upwardly.

The door lock of claim 13, wherein the bushing further includes an ultraviolet inhibitor. 15. The door lock of claim 13, wherein the bushing is made of ultra high molecular weight polyethylene. 16. The door lock of claim 13, wherein the bushing further includes an ultraviolet inhibitor. 17. The door lock of claim 11, wherein the bushing is made from a material selected from the group consisting of polyethylene, delrin, urethane, moly disulfide filed nylon, manganese, bronze, ceramics and combinations thereof. 18. The door lock of claim 11, wherein the end cap is made of a dry, self-lubricating and non-hygroscopic material. 19. The door lock of claim 18, wherein the end cap includes an ultraviolet inhibitor. 20. The door lock of claim 18, wherein the end cap the end cap is made of ultra high molecular weight polyethylene. 21. The door lock of claim 18, wherein the end cap includes an ultraviolet inhibitor. 22. The door lock of claim 11, wherein the end cap is made from a material selected from the group consisting of polythylene, delrin, urethane, moly disulfide filed nylon, manganese, bronze, ceramics and combinations thereof. 23. The door lock of claim 11, wherein the bushing and end cap are made of a dry, self-lubricating and non-hygroscopic material. 24. A lubricant-free door lock for a railroad car, said door lock comprising: a tubular housing; a bushing mounted in the housing; a locking pin slidably mounted in the housing and extending through the bushing; an end cap mounted on an end of said locking pin opposite the bushing and at least partially slidably mounted in said housing, wherein the bushing and end cap co-act to prevent the locking pin from directly engaging the housing, and wherein the end cap is made from a material selected from the group consisting of polyethylene, delrin, urethane, moly disulfide filed nylon, manganese, bronze, ceramics and combinations thereof; a limiter connected to the housing, locking pin and end cap for limiting the movement of the locking pin and end cap relative to the housing; and a biasing member positioned in the housing between the bushing and end cap for biasing the end cap from the bushing. 25. The door lock of claim 24, wherein the housing is substantially cylindrical. 26. The door of lock of claim 24, wherein the biasing member is a spring journaled about the locking pin. 27. The door lock of claim 24, wherein the bushing is made of a dry, self-lubricating and non-hygroscopic material. 28. The door lock of claim 24, wherein the bushing is made from a material selected from the group consisting of: polyethylene, delrin, urethane, moly disulfide filed nylon, manganese, bronze, ceramics and combinations thereof. 29. The door lock of claim 24, wherein the bushing is made of ultra high molecular weight polyethylene. 30. A lubricant-free door lock for a railroad car, said door lock comprising: a tubular housing; a bushing mounted in the housing, wherein the bushing is made of ultra high molecular weight polyethylene; a locking pin slidably mounted in the housing and extending through the bushing; an end cap mounted on an end of said locking pin opposite the bushing and at least partially slidably mounted in said housing, wherein the bushing and end cap co-act to prevent the locking pin from directly engaging the housing; a limiter connected to the housing, locking pin and end cap for limiting the mov ement of the locking pin and end cap relative to the housing; and a biasing member positioned in the housing between the bushing and end cap for biasing the end cap from the bushing. 31. The door lock of claim 30, wherein the housing is substantially cylindrical. 32. The door of lock of claim 30, wherein the biasing member includes a spring journaled about the locking pin. 33. The door lock of claim 30, wherein the end cap is made of a dry, self-lubricating and non-hygroscopic material. 34. The door lock of claim 30, wherein the end cap is made from a material selected from the group consisting of polyethylene, delrin, urethane, moly disulfide filed nylon, manganese, bronze, ceramics and combinations thereof. 35. A lubricant-free door lock for a railroad car, said door lock comprising: a tubular housing; a bushing mounted in the housing; a locking pin slidably mounted in the housing and extending through the bushing; an end cap mounted on an end of said locking pin opposite the bushing and at least partially slidably mounted in said housing, wherein the bushing and end cap co-act to prevent the locking pin from directly engaging the housing, wherein the end cap is made of ultra high molecular weight polyethylene; a limiter connected to the housing, locking pin and end cap for limiting the movement of the locking pin and end cap relative to the housing; and a biasing member positioned in the housing between the bushing and end cap for biasing the end cap from the bushing. 36.
