The line shown as BK extends to the tell and is known as the "hot side" of the electrical system It provides a circuit
to the door switch and ulumately to all electrically operated components through the timer switches You will note
that dashed lines enclose the timer, cycle selector, and door switches This is to indicate that these switches are
inside the component structure
Ester Line Charts
To use the wiring diagram in diagnosis, i_ is very important that you understand the Ester tine charts This chart, as
shown in Figure68, is used to determine when and forhow tong a particular circuit or circuits are energized The
heavy shaded bars represent the period of lime the internal switches of the timer are closed

Most circuits pass through the selector switch The switch functions are shown at the lower left corner of the esteriine
chart A power loss at the input side of the timer may be caused by a defective selector switch,
Input and output terminals of the timer are easily determined by referring to the order of timer terminal markings at
the Ester fine charts' left side The input color listed first, and the output color listed last. To completely understand
the relationship between the wiring diagram and esterline chart, refer to the following example and Figures 69 and 70,
Example
Begin at the fill phaseof the cycle when a normal wash has been selected. The following timer switch contacts are now
closed(Refer to FigureGg;
• Power Bus I - Switch 1
• Timer Motor- Switch I0
• Water Valve - Switch 24
