The new "Clean Design" dishwasherline has been
developed
to satisfy areductioninenergyrequire-
mentsand
to addnewmodelfeatures. Thechanges
are in
number of cycles, time of fills, wash arm
configuration, appearance, control panel cover,
sump cover, filter frame, piston and nut shaft
height, Calrod shape, new Low Travel switches
and
indicator lights. Astyrofoam moisturebarrier
has been changed in
the inner door. The power
shower hose is smaller diameter, and on the low
end models is packed with the clamp and placed
in the
upper rack for shipment.
"SmartWash" Wash Arm
Clean Design DISHWASHER
The appearance is a continuation of the "EURO"
look flush front, and the model line Low Travel
switches and
Indicator lights give the electro-
mechanical models the
"electronic" look. Use of
chrome trim has been reduced and matching color
trim is the norm.

WASH ARM SERVICE AND DISASSEMBLY:
1. Check spray arm holes for bits of china, seeds
and
other foreign matter.
2. Check spray arm rotation.
3. Remove nut tower (illustration on the right) -
LEFT HAND THREADS-
by using ascrewdriver-
blade.
4. Lift out Power Tower assembly and Nut Tower.
5. Remove 1(4" hex head screw from the center of
the wash arm to release arm.
6. Spray arm hub and entire spray arm assembly
can be removed
by turning spray arm hub (right
hand threads) and removing.
7. Reverse to reassemble.
The
illustration are right shows the parts that are
common to both the Standard and the Whirlybird
spray arm sytems. Parts that are interchangeable
are:

MOTOR STALLED-HUMS
1. Remove power. Try to turn fan blade clock-
wise to determine if seal is tuck and can be
broken loose. If motor shaft can not beturned,
cutter blade may be bound up. Proceed to step
#2.
2. On inside of dishwasher, remove sump cover
as shown on illustration at right. Remove the
grid and reach down into the sump. Check for
blockages such as bone, wire ties, etc. Check
"pocket" on left side of sump; if it contains
debris, clean
thoroughly. If motor s haft cannot
be turned, remove mechanism.
AMOUNT OF WATER-CHECKING
Check level allowing dishwasher to fill normally
for first fill. Measure the water level by standing
arule
on the pedestal in the tub bottom center,
just in front of the spray arm hub. The water
level
should be 3/S" to 1" high. If the water level
is to low, check for clogged screen in water
valve, and check float switch.

CALROD REDESIGN
The illustrations to the right also show the new
shape
of the Calrods, to accomodate the new
wash arm design. The Calrod supports have
also been changed
to ametal bracket type with
3
point mounting to prevent the Calrod from
touching the inner door, sides or lower wash
arm. Remove a
114" hex screw in the top of the
Calrod brackets
to remove. The rear support is
also a1/4" hex, with a pivot and hole to
stablilize the bracket. The electro-mechanical
CleanDesign
models all have a500 watt Calrod.

The Low Travel Switch is an innovation that
gives the look of amembrane type touch pad to
pushbutton switches, and provides the "elec"
tronic" appearance to the electro-mechanical
models. While
the touch pad appears exactly
like any
other it does require a light push to
activate the Low Travel Switch pushbutton.
Low Travel Switch pads are organized from the
heavy wash cycles on the left to the lightest on
the right. The Wash Heat Boost and Heated Dry
options can be changed only by first touching
the Options reset LT switch pad. Each Low
Travel switch has an indicator light directly
above it,
which will stay on until the door latch
is opened.
Arotary
dial is used to start the dishwasher, as
well as
start time delay, and other cycles such
as
Short Wash, a rocker switch is used for
Heated Dry on/off on some models.
(Note: The unit is shipped with a protec-
tive film on the etscutcheon. When re-
moved without care it may bend the Lexan
face
which is bonded to an aluminum
panel)

The inner door panel is separated as before with
the exception that the door latch handle will now
pass through the door panel opening without
removal. The illustrations on the right show how
to remove and service the Control Panel assem- :~~~~~:}-------- -

timers are different since they have
reduced
times for fills and 1less fill to accomplish
reduced energy requirements

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 a5400 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.

Cycle extension for models other than the
GSD1400S
occurs in a similar manner. When
Wash Heat
Boost pushbutton is depressed on the
control panel, contacts 9-10 are closed.
This sets
up a circuit through timer switch con-
tacts 4M-4B to terminal H1 on the cycle extender
switch. From H1 the circuit inside the cycle
extender
switch is through a5400 Ohm resistor,
and
through anormally 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 4M-4B that supply power to
H1. Selecting wash heat boost option will extend
wash times
of all cycles except Potscrubberand
Rinse and Hold
by approximately 21 minutes.

Water usage has been reduced by shortening fill
times. (illustration below). The cam
chart below
shows that Potscrubber has 7fills, which can be
from 60 seconds to 42 seconds.
As an example the 1st fill in Potscrubber cycle is
60 seconds, while the intial fill on Short Wash
cycle
is actually fill #3 which is 53 seconds. The
shortest fill time is 42 seconds and is less than
any
of our previous models.
