On a dishwasher wiring diagram, the dishwasher's components are arranged in a three-dimensional frontal view. The wires are represented by black lines, and the wire colors are abbreviated and shown next to each wire. For example, "Y" represents a yellow wire, "V" is used for violet and "R" means red. Black is abbreviated as "BK" and blue is noted "BU." "GRN" or "GN" stand for green, whereas gray is "GY."
In some parts of the diagram, some of the lines may be thicker than others. These thicker areas on the diagram represent wires that are inside the timer. A wire with a dash or slash represents a color with a stripe in it. For example, "BU-W" refers to a blue wire with a white stripe, and "T/R" means tan with a red stripe. Small white circles on the diagram indicate terminals. The terminals are places where it is possible to disconnect the wires from the component for testing purposes. Black dots indicate places where two wires are connected to one another. If two wires cross on the diagram but there is no black dot, then they are not connected. Dotted or shaded lines around a group of wires represent a switch assembly.
