4.1 Chassis
The DishDrawer chassis is one complete assembly composed of 5 steel metal components locked together by a proprietary
riveting process. The chassis exterior is made of a lacquered electro-galvanised material.
4.2 Drawer Fronts
Prefinished drawer fronts are formed from steel blanks. The drawer fronts are attached to the tub by means of formed hooks
and two square pins that are inserted through either side of the tub.
4.3 Electronics
4 TECHNICAL OVERVIEW
The electronics system is made up of 2 separate boards, the wash controller and the motor controller. Each tub has 1 wash
controller, and in the base of the product is a motor controller, which both tub wash controllers are connected to.
The wash controller is the main control. This board controls the wash program selected on the LED display. It monitors the
water temperature, tells the motor controller to activate the lid actuators, wash motor and fill valves as required. The wash
controller also controls the drying fan, detergent dispenser and water softener (if fitted).
The display LED is also connected to the wash controller, and depending on model, may control the tub it is connected to, or
control both upper and lower tubs. There are no secondary touch switches shown on the tub. All cycles are selected through the
display.
The power supply to the wash controller is isolated, but it is still recommended that the power be disconnected from the main
supply before any servicing is carried out.
The motor controller is situated in the base of the chassis, and is connected to the 2 wash controllers by way of a harness.
The motor controller controls the wash motors, fill valves, lid motors and elements on both tubs. It has two 24V rails, one of the
24V power supplies is used for the loads that the motor controller runs, this supply is not isolated and must be treated as live at
all times.
The other 24V supply is isolated and is fed up to the wash controllers to allow them to run their loads.
The motor controller requires several conditions to be met before it will run certain loads. For example, in order to prevent
accidental flooding it won’t run the motor in the wash direction unless the tub is closed and the lids are down.
In addition, except in diagnostic mode, it won’t turn on an element unless the wash motor has prime, which requires the tub to
be closed and the lid to be down.
Unlike previous versions of the DishDrawer, the element is now switched by a double pole relay. This protects against certain
element fault conditions which can occur. The element is further protected by two non resettable thermal limiters.

4.4 Drying Fan
Immediately after water from the final hot rinse has been drained from
the tub, the drying cycle begins.
The drying fan draws air through the vent in the rear into the tub where
it absorbs water from the dish load. The moisture-laden air is then
mixed with a larger quantity of ambient air (drawn from the kitchen),
to minimise the amount of vapour visible when air is exiting from the
bottom of the drawer front.
A flap valve is located in the fan housing. This is closed to prevent moist
air from entering the space behind the door panel during the wash. The
fan runs continuously during the drying cycle for various times
depending on the program selected, 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 anything up to 120 minutes depending on
the program.

4.6 Motor
The motor is a fully electronically controlled 80V, 60w, 3 phase, 6 pole
brushless DC motor, running on wash at between 2200 - 2800 rpm
depending on the cycle selected, and at approximately 5000 rpm on drain.
4.7 Motor 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.
4.8 Spray Arm
The spray arm is shaped for most efficient water flow. 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
are 2 sluicing jets located at the bottom of the spray arm to direct soils
into the drain filter.
The filter plate is positioned below the dish rack and spray arm.
The filter plate has a rubber over mould around the edge and centre to
reduce soil re-depositing.
These improvements will ensure a better wash performance.
The drain filter fits tightly into the filter plate, due to the rubber over
mould around the edge.
4.9 Filter Plate
4 TECHNICAL OVERVIEW
The tub home sensor determines when the tub is closed. The tub home
sensor consists of an infrared transmitter and receiver mounted on the
right side of wash controller. When the tub is fully closed, infrared light
is transmitted from the sender through a light pipe on the side of the tub,
through a prism mounted in the chassis trim, then back through the other
light pipe to the receiver. If the tub is not fully closed, the circuit is not
complete and the appliance will not operate.
4.5 Tub Home Sensor

4 TECHNICAL OVERVIEW
4.10 Drain Filter
4.11 Lid System
The lid is a single piece of polymer plastic with a diaphragm/seal co-injection moulded into it. The centre of the lid can move
relative to the seal. 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 24 volt motor.
When the product is first plugged in and switched on at the wall, the lid motors are powered up to ensure that the lid is fully
raised.
4.11.1 When Activated
At the beginning of the wash cycle, both lid motors are powered up to pull the lid down onto the tub flange in approx 2 -3
seconds. The lid remains down for the duration of the wash and is only lifted when the DishDrawer beeps to signal the end of
the cycle, or if the cycle is paused to gain access to the tub.
If power to the DishDrawer™ fails with the lid down, the tub can still be forced open manually if access is required. It is very
difficult however to close the tub again without raising the lid. The lid actuators can be wound up manually with the tub fully
removed. Failure to raise the lid before closing the drawer can result in the lid seal being damaged.
4.11.2 During a Power Failure
The drain filter is a combination of a large catchment area for solid food
pieces and a fine mesh for straining wash water, it is designed to minimise
soils re-depositing on the wash load.
The Drain filter assembly can be separated into 2 pieces for fine cleaning,
but we recommend rinsing out as one piece. If reassembling use guide
arrows to orientate and ensure they click together snuggly.

16
4.12 Filling with Water
The wash tubs of the DishDrawer fill by a single water inlet hose. Hot water connection is recommended for the USA market
only, while cold water connection recommended for the AU & NZ markets.
From the connection to the water supply tap in the kitchen, the inlet hose enters the cabinet of the dishwasher at the base, into
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 water softener (if fitted) then to the detergent dispenser which directs water
into the tub.
The controller allows only one inlet valve coil to operate at a time, and the top tub always has priority on fill.
4.12.1 Dispensing Detergent and Rinse Aid
The dispenser is mounted in the front of the wash tub, and is held in
place with 2 brackets and 6 T10 torx screws.
The dispenser consists of 2 separate detergent chambers, the large
one is the main wash bucket, the smaller one is utilised for any extra
detergent required for hard water areas.
The detergent dispenser door is opened manually to fill the detergent
buckets, and is then closed manually.
There is a positive displacement pump unit and storage tank
incorporated within the dispenser to dispense rinse aid.
The rinse aid volume dispensed is adjusted through the user
preference options, refer to section 5.
When the rinse aid tank is empty, a glowing red light on the tank filler
cap will alert the customer to refill the rinse aid tank.

4.12.2 Amount of Water
The tub fills with approximately 2.8 litres (3/4 gallon) of water.
The phase 9 model uses a new HYBRID filling system. This new filling system works slightly differently to the older dynamic
filling system by looking for a good consistent prime over a LONGER time period (about 15 secs) and looks for this over a 40
sec period.
4.12.3 Flood Protection
A flood sensor is mounted in the base of the product. It is housed
in the plastic housing. The flood sensor detects any water spillage
and will alert the customer to the flood by showing an E1 on
the display panel and will beep. The drain pump will also run
continously.
4.13 Heating
The heating element is a small circular sheathed element with a
stainless steel flat plate on the wet side.
There are 2 thermal limiters to detect an element over heat
situation. These limiters are non servicable and the element would
need to be replaced should they fail.
The element is held in place by by a cover and 3 torx screws.
4.13.1 Heating Element
4 TECHNICAL OVERVIEW
The initial fill will have up to THREE attempts to find this prime,
so the product will start and stop while filling, and will initially
look overfilled, as water will be up to the bottom of the spray arm
(this is normal).
If this prime is found then some EXTRA water is added depending
on which cycle was chosen and washing starts. If not there is now
a series of small fills to CREEP up on the Prime to make the same
decision.
This series of small fills gradually increases till this prime is found,
this is how LOW PRESSURE (which is low fill rate) will accurately
find prime as well.
So the series of short fills IS NOT a fault, but a more robust
detection process and will ensure the product does not get any
large overfills.

4.13.2 Heating the Water
The heater plate is situated below the water duct cover. The water
is passed over the heating element during the wash cycle via the
duct. The heated water is then picked up by the motor rotor and
distributed to the wash load via the spray arm.
4.13.3 Maintaining the Temperature
The water temperature is monitored by a thermistor situated
in the base of the tub.
It is connected to the wash controller, which monitors the
water temperature.
4.14 Drain Cycle
The drain pump is a self priming centrifugal pump that only pumps
when the motor is rotating in the drain direction (anti-clockwise). It
has a 5 blade impellor pushed onto a spline on the lower 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 drain sump in the tub, and is
sealed by a small o-ring.
The outlet pipe has a non-return valve to prevent soiled water
returning to the tub.
The drain hose is an extruded blow moulded hose that is routed
through the link assembly and exits out the base of the product and
is connected to the domestic drain.
The drain speed during the drain cycle is approx 5000 rpm. In the
hardware output diagnostic mode, it is set at the same speed as drain,
to help diagnose drain problems.

4.15 Water Softener ( some markets only)
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 of the resin is controlled by the electronic controller.
Delivering Softened Water: - Supply water arrives from the inlet valve then through an inline Strainer to remove large deposits.
The strainer is attached to the water softener by an inlet spigot.
Strainer Spigot
In the water softener the water passes through an air break and a diverter valve. It is then either directed
through the resin to the dispenseras softened water, or directly to the dispenser, then into the tub.
The electronic controller measures the volume of water treated soft water, and adds an appropriate amount of non-treated hard
water, to deliver a mix that is at the required hardness according to a pre-determined schedule. Water is treated according to its
supply hardness. The customer is able to select one of 5 supply hardness 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 five 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. The frequency
of the pump is 3 Hz, and makes a slight rattling sound. Later in the wash cycle, 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. During the flush the fill
valve turns on and off alternately for 5 seconds for a number of times depending on the hardness setting. 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 if one is fitted. 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) or 375 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 (63 gallons) at 30 – 100 ppm from 375 ppm supply water (setting 3)
144 litres (38 gallons) at 30 – 100 ppm from 625 ppm supply water (setting 5)
