DISHWASHER •
Some electro-mechanical CleanDesign models
have
Potscrubber
cycle,
and
Wash Heat
Boost
option.
When
the
Potscrubber
pushbutton
is depressed
on
the
control
panel,
contacts
19-20 are closed.
This
set
up
a
circuit
through
timer
switch
contacts
5M-5B
(that
are
closed
during
main
wash)
to
terminal
Hi
on the Cycle Extender
Switch.
From
Hi
the
circuit
inside
the
extender
is
through
a 5400 Ohm resistor, and
through
a
normally
closed
set
of
switch
contacts
to
terminal L2,
which
goes
to
the
other
side
of
the
power
supply.
The 5400 Ohm
resistor
heats
up
and causes
the
bi-metal
switch
contacts
H2-L2
to
open. When
this
happens,
the
timer
motor
circuit
is opened,
and
the
resistor
circuit
is
also opened.
When
the
bi-metal
switch
cools
down,
the
switch
contacts
H2-L2 reclose, and the
timer
starts
running
again, and
the
resistor
heats
up
again.
This
action
is repeated
over
and over
until
the
timer
motor
moves
the
cam enough
to
open
up
timer
switch
contacts
5M-5B
that
supply
power
to
Hi.
The GSD1400T is a
full
featured electro-me-
chanical
model
and has Wash Heat
Boost
option
and
Potscrubber
cycle.
During
the main
wash
cycle
the
Wash Heat
Boost
option
oper-
ates when
contacts
17-18 are closed.
This
sets
up
the
circuit
through
timer
switch
contacts
7M-
7B. This
condition
causes
the
extension
of
Potscrubber
cycle by approximately
11
minutes,
and
other
cycles
by
approximately
21
minutes.
