3.0 TECHNICAL OVERVIEW

3.1 Chassis

The DishDrawer chassis is one complete assembly composed of 5 steel metal components locked together by a
proprietry riveting process. The chassis exterior is made of a lacquered electrogalvanised material called
Galvoclean.

Unlike most other dishwashers, the chassis assembly is a load carrying structure designed to impart stiffness to the
product and to ensure deflection is minimised.

The feet of the Double cabinet are assembled into the chassis by means of four steel inserts which are clinched in
place to form a permanent threaded connection.

The tub extends 520mm (2015/32”) out of the cabinet by travelling along two rigidly attached slides on either side of
the tub.

3.2 Drawer Fronts

Prefinished drawer fronts are formed from a painted, brushed or Iridium finish stainless steel blank. The drawer
fronts are attached to the tub by means of formed hooks and two pins which are inserted through either side of the
tub.

On the integrated model, the front panel supplied on each drawer is the mounting panel for the joinery finished
drawer front. The joinery finished drawer front is supplied by the customer.

3.3 Electronics

In the DD603/ DS603 (Phase 3) electronic controller the functions of controlling the motor as well as controlling the
user interface console have been combined into a single 16-bit Micro Controller on the main printed circuit board.

This Micro controller also controls a transformerless 85w switchmode power supply. This power supply utilises a
large dropping resistor on the heater plate in conjunction with phase control of the mains voltage in order to produce
a variable voltage rail. From this the controller can supply voltages from 5V to 85V to the various components in the
DishDrawer.

NOTE:- With power supplies of this nature all components regardless of supply voltage should be treated as live to
earth. i.e = supply voltage.

The user interface comprises a printed circuit board for front controls and a touch switch panel for internal controls.

The electronics can connect to a computer service tool via an optical light pen for fault finding and product
information.

The element is switched by one single pole relay. Overheat protection is effected by a short length of solder in series
with the dropper resistor track on the heater plate. In an overheat situation this solder melts causing the power
supply to go open circuit.

3.3.1 Tub Home Sensor

A tub home sensor is used to determine when the tub is closed and it is safe to start a cycle. The tub home sensor
consists of an inferred LED (sender) and an inferred transistor (receiver) mounted on the circuit board in the
controller. Inferred light is transmitted from the LED through an optical light pipe to the right hand side of the tub. The
inferred receiving transistor also has an optical light pipe leading from it out to the side of the tub. When the tub is
closed the two light pipes are optically connected via a prism mounted in the trim on the side of the chassis.

- 11 -

March 2004 Manual 599082

3.3.2 Touch Switches

Two touch switches are used on the secondary control panel one to select the required wash cycle and one to turn
the Eco option on or off. They are capacitive touch switches and are supplied with an analogue signal from the
controller that will change in the presence of an earthed mass (i.e. customer’s finger).

3.4 Motor

The motor is a fully electronically controlled 80V, 60w, 3 phase, 6 pole brushless DC motor, running on wash at
between 2300-2850rpm depending on the cycle selected and at approximately 4200 rpm on Drain.

3.4.1 Rotor

The rotor is a four pole permanent magnet rotor with a graphite bearing at each end of the vertical shaft. At the
lower end of the rotor shaft is the drain impellor and at the upper end is the wash impellor.

3.4.2 Spray Arm

The spray arm is shaped for most efficient waterflow. The holes are positioned for best penetration into the wash
load, with the water jets angled to ensure the spray arm rotates at the most efficient speed. There is a flap valve
moulded into the top of the spray arm. This part lets air through the spray arm when the DishDrawer is filling with
water. The DishDrawer fill levels are more consistent with the flap valve system.

3.5 Wiring Cover

The wiring cover protects the customer from all electrical components in the motor area underneath the tub. All
electrical components regardless of voltage should be treated as live with respect to earth. It also serves to protect
the motor assembly, drain and fill hoses from damage when opening and closing drawers. The wiring cover acts as
a cosmetic part of the product.

3.6 Lid System

3.6.1 Lid Operation

The lid is a single piece of polymer plastic with a static seal co-injection moulded into it. Each side of the lid is clipped
into a yoke which is in turn connected to a worm drive lid actuator assembly containing a small brushed DC 24V
motor.

3.6.2 When Activated

At the beginning of each wash cycle, both motors are powered for approximately 10 seconds, which pulls the lid
down onto the tub in approx 5 seconds. The lid remains down for the duration of the cycle and is only lifted when the
DishDrawer beeps to signal the end of the cycle or if the customer pauses it to gain access to the tub.

3.6.3 During a Power Failure

If power to the DishDrawer fails with the lid down you can still force the tub open manually if access is required. It is
very difficult however to close the tub again without lifting the lid. The lid can be wound up manually with the tub fully
removed. Failure to raise the lid before closing the Drawer could result in the lid seal being damaged.

3.7 Tub

The tub is the main cavity where all the wash activity occurs. The tub is a polymer plastic receptacle which has a
wash pump and spray arm at the base. The tub also has guide vanes around its walls which direct falling water from
the wash cycle in a clockwise direction around the filter plate. This clears the filter plate of food particles into the
sump where they can be trapped or pumped out during the drain cycle.

- 12 -

March 2004 Manual 599082

3.8 Filling

3.8.1 Water Inlet

The tub of the DishDrawer fills by a single water inlet hose, hot water connection for USA and Japanese products
and cold water connection recommended for the Australasian/UK/ Europe products. From the connection to the
water supply in the kitchen, the inlet hose enters the cabinet of the dishwasher at the base, onto a dual water valve.
Each tub is supplied water independently via one of the dual valve coils and a fill hose that runs through a
customised link assembly at the back of each tub and travels along the base of the tub under the wiring cover to the
front. At the front of the tub, the fill hose connects to the detergent dispenser which allows water to enter the tub,
firstly through the pre rinse section of the dispenser for the pre rinse cycle and secondly through the main wash
section for all other cycles.
In a product fitted with a water softener, water is directed through the softener before entering the dispenser.

3.8.2 Dispensing Detergent and Rinse-aid

The dispenser is mounted in the front wall of the wash tub.

The detergent dispenser consists of two detergent chambers, one for pre wash and the other for the main wash.

The detergent dispenser door is opened manually for detergent loading and then manually closed ready for the
detergent to be transported to the wash tub by the inlet water. To enable each detergent chamber to be dispensed
separately, an inlet water diverter valve controlled by the electronics is required.

Additionally a positive displacement pump unit and storage tank are incorporated within the dispenser to supply rinse
aid. The rinse aid dispensed volume can be adjusted by the customer in option adjustment mode. A glowing red
light on the tank filler cap indicates an empty rinse aid tank.

3.8.3 Amount of Water

The tub fills with approximately 2.5 litres / 0.8 US gallons of water, approximately level with the base of the spray
arm. Once this level is reached, the wash pump (which has sensed the fill via the electronics) becomes primed and
pumps the water through the spray arm which will then rotate. The load on the wash pump is constantly monitored
throughout the wash cycle and the water level adjusted if necessary.

3.9 Heating

3.9.1 The Element

The heater plate is an element consisting of a porcelain enamelled steel plate with a thick film resistive circuit printed
onto the dry side. As well as the heating circuit a large dropping resistor is also printed onto the heater plate which
forms part of the controllers power supply. The element is clamped in place by a lockring nut and supports the motor
at the base of the tub.

3.9.2 Heating the Water

The heater plate lies beneath the filter plate. A flow through water heating system is created during the wash cycle
by allowing water to flow through the filter plate, over the surface of the element and into the wash pump.

3.9.3 Maintaining the Temperature

Attached to the element is a sub printed circuit board with a temperature sensitive thermistor. This connects by
means of a RAST 2.5 connector system to the wiring harness of the element. Sensor components are
unserviceable and if they fail a new heater plate is required.

- 13 -

March 2004 Manual 599082

3.9.4 Overheat Protection

The heater plate is only activated during the wash cycles. It is not used for drying. The temperature is maintained
by the thermistor. If a failure occurs with the electronic control of the heater plate, overheat protection is effected by
a thermal fuse on the heater plate itself.

The thermal fuse consists of a short length of solder in series with the dropper resistor track which will melt at a
relatively low temperature, 268 – 302oC (514 – 576oF) causing the controllers power supply to go open circuit
disconnecting power to the element.

3.10 Lockring Nut

The lockring nut holds the heater plate into the base of the tub and motor housing assembly to form a watertight
seal. It does this by compressing two large ‘O’ rings between the heater plate and tub and between the heater plate
and the motor assembly.

It has clips which hold the drain hose, fill hoses and the wiring loom in place.

Another function of the lockring nut is to support the wiring cover with three clips.

3.11 Drain Cycle

The drain pump is a self priming centrifugal pump which only pumps when the motor is rotating in the drain direction
(anti-clockwise). It has a five bladed impellor pushed into a spline on the end of the rotor shaft.
The drain pump housing, which incorporates an inlet and outlet pipe, is welded to the motor housing, hence
captivating the motor.
The inlet pipe plugs straight into the sump and is sealed there by a small ‘O’ ring.
The outlet pipe has a non return flap valve to prevent soiled water returning to the tub.
The drain hose is an extruded blow mould hose which is routed over the link assembly and exits out of the base of
the product and is connected to a domestic drain.
The drain speed during the wash program is approx. 4200 rpm. In hardware output diagnostics test mode it is
approx. 5000 rpm. This can account for draining OK in diagnostics but not during normal operation.

3.12 Filter Plate

The filter plate is a stainless steel disk which lies below the dish rack and spray arm and completely encompasses
the base of the tub.

3.12.1 The Filter System

The tub is designed with vanes which swirl the water around and over the filter plate. At the front of the tub, located
as part of the filter plate, is the drain filter. Large soils collect in the drain filter and only smaller soils flow through its
micro mesh filter, eliminating re-depositing of soil during the wash. The drain filter should be regularly checked and
cleaned.

3.12.2 Removing and Cleaning the Filter Plate

The drain filter can be emptied with the dish rack in place by removing the cutlery basket and opening the plastic
section of the dish rack. The filter plate is removable for cleaning by removing the dish rack and spray arm and
unlocking the lockring nut anti-clockwise.

3.13 Drying Cycle

Immediately after water from the final hot rinse has been drained from the tub, the drying system begins operation.

The drying fan draws air through from the vent in the rear of the tub, where it absorbs water from the dish load. The
moisture laden air is then mixed with a larger quantity of ambient air (from the kitchen), to minimise the amount of
vapour visible when exiting from bottom of the drawer front.

- 14 -

March 2004 Manual 599082

The fan runs continuously during the drying cycle and will restart if the tub is opened and closed again. After the
wash program is complete, the lid drives up, and the fan continues to run for 30 minutes, but will not restart if the tub
is opened.

3.14 Water Softener (where fitted)

The Water Softener uses a softening material (resin) to prevent most of the elements that cause hard water from
being present in the wash water. The resin can only treat a limited amount of water before it needs to be
regenerated. Regeneration is achieved by pumping salty water (brine) through the resin, and flushing away the hard
elements to the drain. The process of delivering softened water, and regeneration is controlled by the Electronic
Controller.

Delivering Softened Water:- Supply water arrives from the inlet valve. In the water softener it passes through a
piper interrupter (air break) and a diverter valve. It is then either directed through the resin to the dispenser, or
directly to the dispenser, then into the tub. The electronic controller measures the volume of water treated, and adds
an appropriate amount of non-treated water, to deliver a mix which is at the required hardness according to a pre­determined schedule. Water is treated according to its supply hardness. The customer is able to select one of 5
settings in option adjustment mode.

Regeneration:- Regeneration is triggered when the amount of water that has been treated since the last
regeneration nears the capacity of the Water Softener. The quantities treatable for each of the 5 settings of supply
hardness have been predetermined, and are stored in the electronic controller. When triggered, immediately after
filling for the main wash, the brine pump is activated and delivers a volume of salty water into the resin, at an amount
appropriate to the hardness setting. When the wash cycle finishes, the resin is flushed with supply water, and the
by-products of regeneration are delivered into the wash water, and drained with it away to waste. Normal treatment
of incoming water then resumes.

Salt:- the customer is required to fill the salt tank with dishwashing salt from time to time. Salt is used in the water
softener by mixing it with water to produce the salty water (brine) used in regeneration. When the salt level is low, a
salt level detector causes a glowing red light to appear in the salt bung, and a “Salt” symbol appears in the LCD.
When this happens, the customer should remove the salt bung, and using the salt container provided, pour salt into
the salt reservoir until salt can be seen at the opening. The “Salt” symbol on the LCD will disappear and the red light
will not be visible when the salt tank bung is replaced. In areas where the supply water is moderately hard (21 dH –
degrees of hardness, 375ppm – parts per million, Water Softener Setting 3) the salt reservoir will need to be filled
about once a month, and in harder areas more frequently. Delivery of treated water from one fill of the salt reservoir:

240 litres at 30 – 100 ppm from 375 ppm supply water
144 litres at 30 – 100 ppm from 625 ppm supply water

cycle you want. Then turn the DishDrawer off again reenter diagnostics and restart the Continuous Cycle as above.

Press Power to Exit at any time.

Cycle Count Retrieval

(not available on integrated models)

To display the cycle count on the LCD screen, pause the DishDrawer while running a Continuous Cycle. The two
bytes of the cycle count will be displayed alternately, in syncronisation with the changing backlight.
The Low byte is displayed when the backlight is Off.
The High byte is displayed when the backlight is On.

To calculate the Total DishDrawer cycle count use the formula below.....

Cycle_Count = (200 x High_byte) + Low_byte.

Eg. Low_byte = 156

High_byte = 2
Cycle_count = (200 x 2) + 156 = 556.

5.1.7 Temperature & Voltage Display Mode

7.0 FAULT CODES

The faults are displayed in the LCD as one of 5 F (fatal) faults or 1 U (user) fault along with the symbol of a spanner.
A fatal fault will usually require the assistance of a qualified service person, while a U1 user fault indicates the
machine had failed to prime within a certain length of time usually because the tap has not been turned on. For this
reason at the same time a U1 comes up in the display we also show the symbol of a tap. In the Integrated models,
an LCD is not available, and the presence of a fault is indicated by a Red center LED, with the fault number
indicated on the touch switch panel with Red LED’s.

Once a fault is repaired it can be cleared by pressing the Power button. If the fault is still present then it will not
clear.

A fatal or user fault is accompanied by a continuous pulsating beep which can be turned off by pressing either the
power, start/pause, or key lock button.

The last two faults are logged into EE memory.

The other U (user) faults have been removed. The old U2 fault, which was the tub forced open during a cycle, has
been removed completely. Instead if the tub is forced open the product simply pauses as if someone had pressed
the start/pause button. The old U3 fault, which indicated a failure to drain i.e. water left in the tub, will not show up a
fault and the DishDrawer will continue through the cycle.

March 2004 Manual 599082

Customers Complaint Coffee/Tea Stains left in Cups

Cause of problem
(1)

How to resolve the
problem

Not enough detergent being used. To remove these stains requires a stronger
concentration of detergent in the water.
More detergent is also required in hard water areas as minerals in the hard water
reduce the effectiveness of the detergent.

Fill the main-wash detergent cup to the top & for best results also fill the pre-wash
detergent cup. Run on normal or heavy cycles not Eco.

Cause of problem (2)

How to resolve the
problem

The product is being over loaded which is preventing water reaching the cups on the
upper cup racks.

Advise customer of correct loading.

Customers Complaint Dishes have blotchy marks on them that look like water stain

marks not food

Cause of problem

How to resolve the
problem

Not enough rinse aid being used. The water is not soft enough during the final rinse
and therefore hard water droplets containing impurities are drying on the dishes
instead of running off during the dry cycle.

Confirm that the customer is using rinse aid.

The rinse aid may need to be turned up to a higher setting (4 or 5 lights) and for
optimum dry performance run the DishDrawer on normal or heavy cycles not Eco.

Check that the rinse aid dispenser is dispensing correctly in diagnostics.

Customers Complaint Glasses & Cutlery have a Cloudy White film on them and/or Plates

have a White Chalky film on them

Cause of problem

How to resolve the
problem

Hard water & not enough detergent being used. Minerals from the water are building
up on the dishes or the Water Softener is not set to the correct Water Hardness
Level or is faulty.

Once this film forms on the dishes it cannot be removed by normal running in the
dishwasher. The dishes will need to be cleaned by soaking them in an acidic
solution such as white vinegar and water.

Where a Water Softener is not fitted;

To prevent the build up re-occurring the customer will need to fill both the main-wash
& pre-wash detergent cups to the top with a power detergent and we would
recommend running on normal cycles.

In problem areas with very hard water the customer may need to use a detergent
additive designed for use in hard water areas or fit a water softener to the incoming
water supply.

Where a Water Softener is fitted;

Set the Water Softener for the correct local Water Supply hardness. Check that the
Water Softener is functioning correctly in Diagnostics;

C1 Water Softener Diverter Valve

- 33 -

March 2004 Manual 599082

In hardware output Diagnostics Test Mode

FU – turn the Fill Water Valve on
P2 – turn the Motor Drain on
C1 – Water Softener Diverter Valve

On – water bypasses the resin tank
Off – water flows through the resin tank

C2 Water Softener Brine Pump

Turn the Brine Pump on in Diagnostics mode. Observe a small quantity of water
(approx. 30 ml per min.) flowing out the bottom of the dispenser. (Drop the
Dispenser Door down to observe this.) Observe a change in the water level
(approximately 120ml per 4 min.) in the Salt Reservoir. The Reservoir should pump
dry of water in this time.
Note:- Fill the Salt Reservoir with Salt (and then water if not already) before
performing this test.

Pipe Interrupter (Air Break) Function

A critical component in the performance of the Water Softener is the pipe Interrupter
(PI). There is a certain amount of spray leakage from the PI which is used to provide
water to the Salt Reservoir.

If the spray is inadequate, there will be insufficient water in the Salt Reservoir to
make Brine.

If there is too much spray then the excess bypasses the Water Softener and defeats
the softening process by pouring untreated water into the Tub.

To check that the amount spray leakage is appropriate:-

Fill the Salt Reservoir with water.

In diagnostics mode, Turn on the Fill Water Valve, and the Motor Drain. Water will
flow out of the Dispenser into the Tub, as well as out of the Water Softener Overflow
into the Tub.

Observe the flow from the Water Softener Overflow (beside the Dispenser). There
should be a trickle (25-100 ml per minute). With experience you can guess what is
appropriate. If the trickle is outside these rates, replace the softener as the PI is
faulty.

To check that there is water in the Salt Reservoir, remove the Drawer front and
observe the level of water in the tank. (A quick way to check that there is water in
the Salt Reservoir is to remove the Salt Bung and test the water level by placing
your finger down through the opening.)

Detergent or Rinse Aid in the Water Softener

If detergent or rinse aid is poured in to the Salt Reservoir it will destroy the Water
Softener. This could also happen if the Salt Bung is left off or falls out. Evidence of
this could be white streaks through the Resin.
