3.0 TECHNICAL OVERVIEW
3.1 Electronics
The DD601 electronic controller has two separate micro controllers on the main printed circuit
board. One is for motor control and output switching and the other is for controlling interface and
console functions.
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 a serial communications port for fault
finding and product information.
All output peripherals (solenoids, fans etc), except the heating element, are run on low voltage
(24v).
The power for all low voltage devices comes from a 100w switchmode power supply, which is
cooled by a heatsink and when necessary the drying fan.
The element is switched by a relay and protected by a fail safe relay.
3.2 Motor
The motor is a fully electronically controlled 40V 60w 3 phase 6 pole brushless DC motor,
running at approximately 2300-2850 depending on wash cycle selected, 2500 rpm on Normal, Fast,
and Rinse cycles, 2300 on Delicate and 2850 on Heavy Wash, 4200 rpm on Drain.
3.3 Cabinet
3.3.1 Chassis
On the double drawer the double chassis is one complete assembly composed of 5 steel
metal components locked together by a proprietry riveting process. The chassis exterior is
made of white prepaint, while other components are made of electrogalvanised material.
On the single drawer four bolts and washers are used to secure the chassis to the shelf using
the steel inserts.
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 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 510mm out of the cabinet by travelling along two rigidly attached slides on
either side of the tub.

- 9 -
3.3.2 Drawer Fronts
Prefinished drawer fronts are formed from a prepainted blank of steel. 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.
3.4 Filling
3.4.1 Cold Inlet
The tub of the dishwasher fills by a cold water inlet hose only. From the connection to the
cold water pipe 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 customised link assemblies at the back of the
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.
3.4.2 Mixing the Detergent
Filling cold water enters the detergent dispenser, flushing the detergent from the cup,
through the dispenser into the tub.
3.4.3 Amount of Water
The tub fills with approximately 2.2 litres of water, level with the base of the spray arm
attachment. Once this level is reached, the wash pump (which has sensed the fill at 30
second intervals during the fill), becomes primed and pumps the water through the spray
arm which will then rotate.
The water level is monitored by sensing the motor load through the electronics.

- 10 -
3.5 Dispensing Detergent
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 necessary.
Additionally a positive displacement pump unit and storage tank are incorporated within the
dispenser to supply rinse aid. The rinse aid dispensed volume is adjusted utilising the dishwasher
electronic controller. A glowing red light on the tank filler cap indicates an empty rinse aid tank.
3.6 Lid Seal
3.6.1 When Activated
At the beginning of each wash cycle, the lid seal inflates while the pre wash drain cycle
removes any residue water from the tub. This runs for approximately 60 seconds, then the
tub fills.
3.6.2 What is the Lid Seal
The lid seal is a static plastic moulding retained in the lid which provides a dynamic seal to
the tub. The dynamic seal is created by a bellows section gasket bridging between the top
flange of the tub and the lid. The dynamic seal also locks the tub/drawer during washing.
3.6.3 During Wash
The bellows section gasket is inflated by a solenoid activated diaphragm air pump. This
cycles during the complete cycle at timed intervals to maintain a 35kpa sealing pressure.

- 11 -
3.7 Wash Cycle
3.7.1 Tub
The tub is the main cavity where all the wash activity occurs. The tub is a plastic recepticle
which has a wash pump and sprayarm 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.
3.7.2 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.
3.7.3 Spray Arm
The spray arm is shaped for most efficient waterflow. The holes are positioned for best
penetration into the washload, with the water jets angled to ensure the sprayarm rotates at
the most efficient speed.
3.8 Heating
3.8.1 The Element
The heater plate is an element consisting of a porcelain enamelled steel plate with a thick
film resistive circuit written onto the dry side. The element is clamped in place by a
lockring nut and supports the motor at the base of the tub.
3.8.2 Heating the Water
The heater plate lies beneath the filter plate. This creates a flow through water heating
system during the wash cycle by allowing water to flow through the filter plate, over the
surface of the element and into the wash pump.
3.8.3 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 unservicable.

- 12 -
3.8.4 Overheating Control
The heater plate is only activated during the wash cycles. It is not used for drying. The
temperature is maintained by the thermistor. The element circuit is continuously monitored
by the electronic controller and will switch a fail safe relay if a fault is detected in the
heater circuit. The element is thermally monitored by the thermistor on the element
through the electronic controller.
3.9 Filter Plate
The filter plate is a stainless steel disk which lies below the dishrack and sprayarm and completely
encompasses the base of the tub.
3.9.1 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 1.5mm or smaller soils flow through its micro mesh filter,
eliminating re-depositing of soil during the wash. Only soils up to 6mm pass through the
drain filter during the drain cycle. This requires the drain filter to be regularly emptied and
cleaned.
3.9.2 Removing and Cleaning the Filter Plate
The drain filter can be emptied with the dishrack in place by removing the cutlery basket
and opening the plastic section of the dishrack. The filter plate is removable for cleaning
by removing the dishrack and sprayarm and unlocking the lockring nut anti-clockwise.
3.10 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 made from acetal pushed into a
spline on the end of the rotor shaft. The drain cycle is a 60 second timed drain period.
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.

- 13 -
3.11 Drying Cycle
Immediately after water from the final hot rinse has been drained from the tub, the drying system
begins operation.
The fan draws air through the tub, where it absorbs water from the dishload. 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 the drawer front.
The fan runs continuously during the drying cycle and will restart if the tub is opened and closed
again. After the drying cycle is complete, the fan continues to run for 30 minutes, but will not
restart if the tub is opened.
The fan is pulsed when needed throughout the entire wash cycle. This draws ambient air through
the electronics heatsink to maintain the electronics components within their specified operating
temperatures.
3.12 Deflating
3.12.1 Lid Seal
The lid seal is a static plastic moulding retained in the lid which provides a dynamic seal to
the tub during the washing cycles.
3.12.2 When the Lid Seal Deflates
At the end of the dishwasher programme, or a pause in the programme, an exhaust valve
releases the air pressure from the bellows section gasket. This deflates the seal and unlocks
the tub and drawer.
3.13 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.

- 14 -
3.14 Wiring Cover
The wiring cover protects the customer from the 240V mains supply which passes over the link
assembly and under the lockring to the front of the tub. 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.
4.0 DIAGNOSTICS
4.1 Setup & Diagnostics
The DishDrawer comes with comprehensive fault codes and built in diagnostics, to save the user &
service person time and worry, if the dishwasher ever exhibits a fault.
4.2 Fault Modes
The faults are displayed in the LCD as one of 8 F (fatal) faults or one of 3 U (user) faults. A Fatal
fault will usually require the assistance of a qualified service person, while many User a faults are
simply blockages or installation errors, easily fixed by the user. In the Integrated models, an LCD
is not available, and faults are indicated by a Red center LED, with the fault number indicated on
the touch switch panel with Red LED’s. The indication below for the Touch Switch Panel is from
left to right, with ‘_’ meaning the LED is Off, and ‘#’ meaning the LED is On. A fatal fault is
accompanied by a continuous pulsating beep, while a user fault is accompanied by a more pleasant
continuous pulsating tone pattern. The last two faults are logged into EE memory, with 8 bytes of
information logged to aid location of the fault. These bytes are available for interrogation by a PC if
required. The fault codes shown on Pages 20/21 have been implemented in the DishDrawer.
To clear any fault press the Power button. It the fault is still present then it cannot be cleared.

- 15 -
4.3 Diagnostic Modes
4.3.1 Temperature Display Mode
During a wash cycle, the current water temperature can be displayed on the LCD instead
of the time remaining. To enter temperature display mode, start a wash cycle as normal.
Initiate a keylock by pushing and holding the Keylock button for 4 seconds.
Once in keylock mode push and hold Start/Pause for 8 seconds to enter temperature
display mode. The temperature is now displayed and the MIN symbol is switched off.
Keylock mode can now be exited.
To cancel temperature display mode, either repeat the above procedure or enter power off
mode by pressing Power. Temperature display mode is automatically cancelled at the end
of a wash program (even in CC mode).
4.3.2 Rinse Aid / Tub-Open Beep Water Pressure Setup Mode
To enter this setup mode, hold the Programme and Eco touch switches simultaneously for

displayed.
Push Power at any time to exit this setup mode.
4.3.3 Rinse Aid Setup
The current rinse aid setting is shown using orange LED’s on the touch switch panel.
The amount of rinse aid dispensed into a rinse cycle can be varied to suit the level of
hardness of the local water supply. It is adjusted for 1 - 5 dispenser levels
(1 = approx 1ml of rinse aid , 5 = approx. 5mls of rinse aid).
Push Programme to advance the rinse aid setting. Once the desired setting is achieved,
push Power to exit. The rinse aid index is stored in EE memory, so even with the power
removed, the rinse aid level is retained.
4.3.4 Tub-Open Beep Setup
The beep sequence that occurs when the tub is opened can be turned on or off using the
Keylock button. If the Smily Face on the LCD is On then the beep sequence will occur
when the tub is Opened. If the Smiley face is Off then no beeps will occur when the tub is
Opened. Push Power to exit when the desired setting has been selected.
The Integrated Model will sound a single beep when turning this option off, while the
actual beep sequence is sounded when turning this option on. The DishDrawer will default
to 'beeps on' if the mains power is removed.

4.3.5. Water Pressure Set Up
The DishDrawer can be set to either High(Standard) or Low inlet water pressure. The LCD
displays the current water pressure setting.
If “HP” is displayed then the settingis High Pressure.
If “LP” is displayed then the setting is Low Pressure. Low pressure is generally less than
50kPa or equivalent to that supplied by a ceiling tank.
Push the Start/Pause button to alternate between HP and LP.
Integrated: A high beep is sounded when changing the HP, and a low beep is sounded
when changing to LP. Push Power to exit when the desired setting has been selected.
4.3.6 Dishwasher Diagnostics
Dishwasher Diagnostics can only be entered in Power Off mode, ie. When there is no
display on the LCD or the badge LED’s are off. Diagnostics is entered by holding the
Keylock and Start/Pause buttons simultaneously for 6 seconds. Ensure that Keylock is
pushed first to prevent the dishwasher from starting a wash, from a Start/Pause keypress.
There are currently four levels of diagnostics. To move to next level push Power. Once a
mode has been entered, pushing Power will exit diagnostics completely (except Display &
Show Off modes). If no mode is entered then the display will cycle through the four levels
and exit after the last. On entering diagnostic mode the first level is Download Mode.
4.3.7 Display / Download Mode
In this mode all LED’s (except Rinse program) and LCD segments (except keylock) are
illuminated.
4.3.8 Optical LED Download / Fault Display
An optical data download is available here to download all EE data to a PC via the Rinse
Program Red LED. Hold the reader pen over the Rinse Program LED and press Start /
Pause to initiate the download. A short beep indicates the start and finish of download.

the backlight alternates between RED and OFF.

- 19 -
Cycle Count Retrieval
To display the cycle count on the LCD screen, Pause the dishwasher 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 Green.
The High byte is displayed when the backlight is Orange.
To calculate the Total diswasher cycle count use the formula below.....
Cycle_Count = ((200 x High_byte) + Low_byte).
Eg. Low_byte = 156
High_byte = 21
Cycle_count = ((200 x 21) + 156) = 4,356.
