The ornamental design for a dishwasher, as shown and described.
FIG. 1 is a top-front perspective view of a dishwasher according to our design;
FIG. 2 is a front view thereof;
FIG. 3 is a right side view thereof;
FIG. 4 is a left side view thereof;
FIG. 5 is a top view thereof; and,
FIG. 6 is a bottom view thereof, a back view thereof showing no claimed portion of the design.
Broken lines are environmental only and form no part of the claimed design.
Dash-dot lines adjacent un-shaded areas represent bounds of the claimed design and form no part of the claimed design themselves.
The diagonal shading using solid lines indicates a transparent material. In particular, the forward-directed (i.e. lower-left to upper-right) shading, indicates a tinted transparent material layer (that is such that the texture represented by the texture shading is visible through the transparent material thereover.
The texture shading depicted beneath the tinted transparent material layer represents a surface texture on the layer on which it is depicted in the form of a metal surface treatment.
