A door assembly selectively permits access to the treating chamber and may carry electronics for the dishwasher. Appropriately placed chamfered fins in a crown in the door aids in assuring a flush fit and finish in a front panel of the door assembly. ## Claims ### Claim 1 A dishwasher door assembly comprising: a front panel having a front wall and spaced side walls extending from the front wall to define a substantially U-shape cross section with an upper edge partially defining an upper opening, wherein the spaced side walls extend along a length of the front wall and define outermost walls of the front panel; and a crown overlying the upper opening and having a front edge and spaced side edges extending from the front edge, and tabs extending downward from a lower surface of the crown and into the upper opening, the tabs having a length such that the tabs are in contact with an innermost surface of the side walls, beneath the upper edge; wherein the tabs are spaced inward from the side edges an amount such that the crown overlies the upper edge and an outermost edge of the side edge aligns with an outermost edge of the side wall such that the side edges are substantially flush with the side walls. ### Claim 2 (depends on 1) The dishwasher door assembly of claim 1, further comprising an inner panel spanning the side walls and having an upper edge partially defining the upper opening, wherein the front panel comprises a return flange extending from the front wall toward the inner panel and terminating in a rear edge adjacent the front edge of the crown. ### Claim 3 (depends on 2) The dishwasher door assembly of claim 2 wherein the front edge and the rear edge are complementary in shape. ### Claim 4 (depends on 3) The dishwasher door assembly of claim 3 wherein the complementary shapes are arcuate. ### Claim 5 (depends on 4) The dishwasher door assembly of claim 4 wherein at least a portion of the front edge overlies the rear edge. ### Claim 6 (depends on 1) The dishwasher door assembly of claim 1 wherein the tabs comprise multiple spaced flanges. ### Claim 7 (depends on 1) The dishwasher door assembly of claim 1 wherein the tabs comprise a chamfer distal from the lower surface. ### Claim 8 (depends on 7) The dishwasher door assembly of claim 7 wherein the chamfer comprises a rounded corner. ### Claim 9 (depends on 1) The dishwasher door assembly of claim 1 wherein the crown comprises a fascia for a user interface. ### Claim 10 A dishwasher door assembly comprising: a front panel having a front wall and spaced side walls extending from the front wall to define a substantially U-shape cross section with an upper edge partially defining an upper opening; an inner panel spanning the side walls and having an upper edge partially defining the upper opening; a crown spacer disposed between the front panel and the inner panel, adjacent the upper opening; and a crown overlying the crown spacer and the upper opening and having opposing upper and lower surfaces bounded by front and inner edges connected by spaced side edges, and tabs extending downward from the lower surface and spaced inward from the side edges an amount substantially equal to the thickness of the upper edge along the side walls to define overhangs from the tabs to the side edges; wherein when the crown is mounted to the front panel, the tabs are received within the upper opening and in contact with an in surface of the side walls, beneath the upper edge, the overhangs overlie the corresponding upper edge along the side wall, and an outermost edge of the side edge aligns with an outermost edge of the side wall such that the side edges are substantially flush with the side walls. ### Claim 11 (depends on 10) The dishwasher door assembly of claim 10 wherein the front panel comprises a return flange extending from the front wall toward the inner panel and terminating in a rear edge adjacent to the front edge of the crown. ### Claim 12 (depends on 11) The dishwasher door assembly of claim 11 wherein the front edge and the rear edge are complementary in shape. ### Claim 13 (depends on 12) The dishwasher door assembly of claim 12 wherein the complementary shapes are curved. ### Claim 14 (depends on 12) The dishwasher door assembly of claim 12 wherein at least a portion of the front edge overlies the rear edge. ### Claim 15 (depends on 10) The dishwasher door assembly of claim 10 wherein the tabs comprise multiple spaced flanges. ### Claim 16 (depends on 15) The dishwasher door assembly of claim 15 wherein the multiple spaced flanges have a chamfered outer surface. ### Claim 17 (depends on 16) The dishwasher door assembly of claim 16 wherein the chamfered outer surface comprises a rounded corner. ### Claim 18 (depends on 10) The dishwasher door assembly of claim 10 wherein the tabs comprise a chamfer distal from the lower surface. ### Claim 19 (depends on 18) The dishwasher door assembly of claim 18 wherein the chamfer comprises a rounded corner. ### Claim 20 (depends on 10) The dishwasher door assembly of claim 10 wherein the crown comprises at least one of a fascia for a user interface or a display.
