DELAY
WASH
TIMER
Model

has
an
eight hour delay
timer
that
is mounted in
the console. See
Figure
1.
This delay
wash timer will delay the
start
of a
selected
dishwasher
cycle
up to
eight hours.
A single-throw
double-pole
switch in the
delay timer controls the start
of
the
dishwasher
cycle. See
Figure

for
the
location
of
the delay
timer contacts
in
the
wiring diagram.
When the
DELAY WASH
feature
is
selected, contacts
T
to
W-G
are closed. lf the DELAY
WASH
fea-
ture
is not
selected,
the T
to
W-O contacts
are
closed and the
dishwasher will
start the selected
cycle
immediately.
The
dishwasher uses a Rapid
Advance
Timer.
RAPID
ADVANCE
TIMER
Model
753900
is
equipped
with
a
Rapid
Advance
Timer.
This
timer does
not have a dial
or
knob. There
are actually two
timer
motors.
One
is a standard-speed
motor that
rotates
the
timer
one
full
revolution
in
68
minutes,
while
the
other
motor turns
rapidly.
The
Rapid Advance
motor
simply
serves
to ad-
vance
the
timer cams
to a
predetermined
star'
ting
position.
This starting
position
is
program-
med
through
the
pushbutton
selector
switch
and
various
contacts
in the
timer itself
for
any
given
cycle selection.
This action
is
similar
to a standard
timer
being
manually
advanced
to
a
SHORT
CYCLE
by the
user
for cycle selection.
The table
in
figure
3
shows
how
the
timer is ad-
vanced through
the cycle
for
any
given
cycle
selection.
Once
the timer
has
advanced
to the
predetermi-
ned
starting
position,
the
electrical circuit
is bro-
ken to the
Rapid
Advance
timer
motor by one
of the timer switches
and
one
of the selector
switches.
The
Rapid
Advance
motor stops
and
the
normal timer
motor takes
over
to
complete
the
selected
cycle.
The timer
is
mounted behind
the access
panel
of the
dishwasher.
To
gain
access
to
the Rapid
Advance
Timer, the
access
panel
must be
removed.
The
timer starts
all cycles,
except the
MlNl
WASH and
ECONO cycle,
at
increment
1
of the
timer.
The
POTS &
PANS
and
NORMAL
WASH cycle
go
through
all
cycles
for
a
complete
360
rotati'
on.
The
RINSE &
HOLD cycle
goes
through
the
first
wash and
rinse
cycles
only. The
RINSE
&
HOLD
cycle
finishes in
increment
14
of
the
timer.
The
Rapid Advance
Motor advances
the
timer
to the
drain cycle
in
increment
39.
When
the
drain cycle
is completed,
the
timer
advances
to the OFF
position.
