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

a metal bracket type with

3 point mounting to prevent the Calrod from

touching the

inner

door,

sides

or lower

arm. Remove a 114 hex screw in the

top

of the

Calrod brackets

to

remove. The rear

support

is

also a

1 4

hex with a pivot and hole

to

stablil ize the bracket. The electro mechanical

CleanDesign

models

all have a 500

Calrod.

The Low Travel Switch is an innovation that

gives the look of a membrane 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 f rom 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.

A rotary dial is used

to

start the dishwasher, as

wel l as start time delay, and

other

cycles such

as

Short

Wash, a

rocker switch

is used

fo r

Heated Dry on/of f 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

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

se t 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

t imer 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

unti l the t imer 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

minutes

and other cycles by approximately

minutes.

Cycle extension

fo r

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

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

t imer 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

t imer 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 Potscrubber and

Rinse and Hold by approximately 21 minutes.

Water usage has been reduced by shortening fill

t imes. (illustration below). The cam

chart

below

shows that

Potscrubber

has 7 f il ls,

which

can be

from

60

seconds

to 42

seconds.

As an example the 1st fil l 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.
