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.
- 5 -
The tub extends 510mm out of the cabinet by travelling along two rigidly attached
slides on either side of the tub.
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.
- 6 -
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.
- 7 -
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.
- 8 -
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 anticlockwise.
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.
- 9 -
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.
- 10 -
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.
- 11 -
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.
- 12 -
4.3 Diagnostic Modes

(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.

display, and the backlight alternates between RED and OFF.
- 16 -
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.
