INTRODUCTION
1. Introduction
You are holding ASKO’s service manual for the DW70 generation of dishwashers.
The DW70 dishwasher series is available in four different basic models, designated DW70.1, DW70.3,
DW70.4 and DW70.5. On the next page, we present the various panels found on each type, making it
easy to identify the different machines. The different models are named differently in different mar-
kets. The type designation is most important when identifying a particular machine model.
The type plate can be found on the right of the inside of the door.
The first two digits specify the year of manufacture
while the third and fourth digits specify the week of
manufacture.
It should be easy to service a dishwasher. It is important that you, as a service technician, are afforded
conditions that enable you to work in an efficient and satisfactory way. Our hope is that this service
manual will prove a useful tool in your daily work.

3. Installation
Suggested machine installations
The dishwasher can be installed built-in,
completely freestanding or partially free-
standing.
CAUTION!
Connections to electricity, water and drain-
age must be performed by qualified profes-
sionals.
A. Built-in
The dishwasher can be installed under a
worktop and integrated with the kitchen
cupboards. Read the instructions in the user
manual and the installation instructions for
the actual machine type.
B. Freestanding
A freestanding machine must be fitted with an
anti-tilt device. This comprises two brackets,
which are screwed into place as illustrated in
figure 1. An alternative to the anti-tilt device
is a counterweight that is fixed directly to the
back of the machine.
Push in the machine so that the rear feet slide
into the mounting brackets. Now the machine
will not tip over if a load is placed on the
door when open. If the machine is installed
completely freestanding, side panels and a
worktop should be fitted. These accessories
can be purchased where you bought the
dishwasher.
C. Partially freestanding
If you install the machine so that either side is
visible, you can fit a side panel.
D. Machines with wooden door
Stronger door springs are available for pur-
chase for machines with a fitted wooden
door. Springs are available for various
weights and sizes of wooden door. Door
springs can be purchased where you bought
the dishwasher. Follow the instructions in
the installation manual for fitting the wooden
door.

Connection to water supply
The supply pipe must be fitted with a stop-
cock. The stopcock should be positioned
above the sink unit or at the front of the sink
unit cabinet.
The inlet pipe has a coupling with either a 1/2”
or a 3/4” internal thread, depending on the
country.
Once the machine in installed: Open the stop-
cock to flush the pipe. Check that all connec-
tions are watertight.
Electrical connection
Machines fitted with a cable and plug must be
connected to an earthed socket.
Technical data
See the type plate on the right-hand side of
the door.
CAUTION!
The power cable must be disconnected or the
power to the socket turned off when work is
carried out!
Drainage connection
• The drainage hose connects to a connec-
tion nipple on the sink unit’s water trap (see
illustration below). Note that the hose must
be attached at the same height as the un-
derneath of the sink unit otherwise dishwater
from the sink may run down into the dish-
washer (see illustration).
• The drainage hose connects to a connection
pipe on the sink unit’s water trap. It must have
an internal diameter of at least 16 mm.
• The drainage hose may be extended to a maxi-
mum of 3 m. Any connections and connecting
pipes must have an internal diameter of at least
16 mm.
• No part of the drainage hose may be more
than 950 mm above floor level.
The hose must not be routed directly to the
floor drain or similar. In such cases, the hose can
act as a siphon and empty the machine.
The hose must always discharge at least 350
mm above floor level.
• Attach the hose holder.

COMPONENT INFORMATION
Flow meter
The flow meter is fitted in the air gap. The
flow meter is used to control the water intake
so that the right volume is taken in regard-
less of the water pressure. It is even possible
to program the machine for time-controlled
water intake.
The flow meter comprises an impeller with two
magnets that is driven by the water flow. On the
outside, on the flow meter housing, is a sensor,
a reed switch, which closes each time the mag-
nets pass. The number of pulses from the sensor
is proportional to the volume of the flowing
water. A minimum water flow of 2 litres/minute
is required for the flow meter to operate. If
the necessary level is not reached within one
minute, the program stops.
Output signal: 220 pulses per litre.
Circulation pump
The circulation pump comprises an asynchro-
nous motor, with a pump component and a
condenser.
Spray arm diverter
Certain machines are fitted with a spray arm
diverter. The spray arm diverter comprises a
synchronous motor that drives a disc valve
via a gearbox. The disc distributes different
4.2Componentsandfunctiondescription
Here we present the functions and specifica-
tions of the various electrical components.
Some components are only found in high-end
machines or in particular markets.
Inlet valve
Both single and safety inlet valves are used.
The valve contains a filter to stop particles then
a flow limiter to limit the flow to a maximum of
4 l/min. The valve opens when the water pres-
sure exceeds 0.3 bar and provides full flow at
about 2 bar.
Safety valve
The safety valve has two independent valve
seats, each controlled by a separate elec-
tromagnet. The valve seats are connected
in series. This doubles the safety factor. The
electromagnets are also connected in series
(electrically), which means each magnet’s
rated voltage is half the mains voltage (e.g., a
230 V valve = 2 x 115 V coils)
Single valve
The single valve comprises an electromagnet
and a valve seat.

COMPONENTINFORMATION
amounts of water from the circulation pump
to the lower and upper spray arms at different
pressures. The motor/gearbox also drives a
cam with four different step times. A switch
detects the cam (step time) and provides
the control unit with feedback on its current
position when setting the desired spray arm
status.
Note that the spray arms never rotate at the
same time. The spray arms can report the
following status:
• Upper spray arm half or full pressure
• Lower spray arm half or full pressure
Depending on the program, dishwashing
stage and options, the spray arms are set to
various intervals and pressures.
Machines that lack a spray arm diverter utilise
a water distributor instead, which routes the
water to both spray arms. The spray arms
always rotate at the same time.
Heating element
The heating element is of the flow-through
type and is fitted between the bottom drain
and the suction side of the circulation pump.
It comprises a pipe with a heating coil. One
side of the heating coil is fitted with an over-
heating cut-out with a trigger temperature
of 98°C and an automatic reset. The other
side is fitted with a safety fuse that blows at
229°C.
Drainage pump
The drainage pump comprises a 30 W syn-
chronous motor and a pump component. The
direction of rotation is random, making the
pump partially self-cleaning.
Fan
The fan extracts the damp air from the ma-
chine during the drying phase of the program.
The fan system has a fan motor that drives
a double-sided fan wheel. Dry air is sucked
in from the opening on one side of the fan
wheel. The hot and damp air from the clean-
ing compartment is drawn through the other
side of the fan wheel, when a Vax motor
opens a damper. This is done with a slight
delay. Dry and damp air are mixed in a con-
duit that ends at the top of the door, where
the air is expelled through a nozzle.
Detergent and rinse aid dispenser
The detergent and rinse aid dispenser is
fitted with an electromagnet which upon first
activation dispenses detergent and upon
second activation dispenses rinse aid. The
system is reset when the dishwasher door is
opened.
The dispenser contains a chamber of adjust-
able volume to set the desired rinse aid dose.
The rinse aid level can be checked using the
optical indicator on the top of the dispenser.
Some models have a sensor, a reed switch,
fitted to the dispenser. This measures the
rinse aid level, which is then indicated on the
panel.
Main power switch
The main power switch has 2 pins and breaks
the phase and the earth. However, power to
the filters, overflow cut-out, drainage pump
and inlet valve is not cut when the main
power switch is turned off.
On the DW-70.4 the main power switch is elec-
tronic and is integrated with the control unit.
It puts the machine into standby mode when
deactivated.
EMC protection
EMC protection ensures that the machine
does not interfere with nearby electrical
equipment. It also protects the machine from
external interference.

12
Door switch
A micro switch detects when the door has
been opened. The program is paused and
power to certain components (motor, valves
etc.) is cut. The program continues where it
left off when the door is closed.
Overflow cut-out
The overflow cut-out comprises a float that
triggers a micro switch. This switches off the
inlet valve electrically and starts the drainage
pump. The protection remains in place even if
the main power switch is turned off.
Light
The light is a 5 W/12 V halogen bulb powered
by a control unit via a micro switch. The lamp
turns on when the door is opened more than
5°. The lamp is dimmed when lit to reduce
the start current and to extend the life of the
bulb. The control unit features protective
components that limit the current to the light
in case of a short circuit or if a bulb with too
high a power rating is fitted. The bulb can be
replaced from inside the cleaning compart-
ment.
Cables
The machine is fitted with coded connectors
to prevent incorrect wiring. The cables com-
ply with the Rast 2.5 and Rast 5 standards.
Water softener
The water softener softens the intake water
to prevent limescale deposits on dishes and
in the machine. The ion exchange resin is
recharged by opening the salt water valve
(found on the water softener) and releasing
water saturated with salt into the ion ex-
change chamber during the main wash. The
ion exchange chamber is rinsed clean at the
end of the main wash.
A mixer valve on the water softener controls
the water passing through or bypassing the ion
exchange resin. The higher the water softener
setting, the greater the amount of water pass-
ing through the ion exchange resin. When the
mixer valve is open, the water bypasses the ion
exchange resin.
Some models have a sensor, a reed switch,
to detect when the salt needs refilling. Other
models use an optical indicator in the salt filling
hatch.
Air gap
On the side of the machine is an anti-back-
flow device to prevent dirty water from being
siphoned back into the water system, such
as if a vacuum develops in the water system.
Machines with a water softener also have a
water pocket that is filled with about 2 dl of
water. This water pocket is emptied when the
salt water valve is activated.
Thermistor
The thermistor is at the front edge of the
bottom drain and detects when the selected
water temperature has been reached. If the
thermistor is short-circuited or detaches
from the circuit board, the heating element is
turned off.
Pressure sensor
The pressure sensor is connected to the
pressure chamber in the bottom drain. It
measures the pressure, which corresponds
to the water level in the machine. If the water
level in the machine is too high (for five con-
secutive seconds) the drainage pump starts
and all other components are switched off.
When the right level is reached, the program
continues where it left off. If the level sensor
generates an output signal of <1 VDC during
the prewash (indicating a blocked filter), an
additional prewash is activated with an SCS
step.
The level sensor also controls the draining time
(can be extended from 25 seconds to a maxi-
mum of 3 minutes). Does not apply to DW-70.1
The sensor also checks the need to refill (such
as if a bowl fills with water). Does not apply to
DW-70.1
COMPONENT INFORMATION

13
Turbidity sensor
Machines with an auto program have a
turbidity sensor that measures how cloudy
the water is. The sensor comprises an LED
and a phototransistor. Between these two is
the dishwater. The less light that reaches the
phototransistor, the cloudier the water. The
sensor is calibrated during the last rinse of
the auto program. At different points during
the auto program the output signal from the
turbidity sensor provides data used to deter-
mine how the program will continue (number
of prewashes, temperature, program time,
number of rinses and so on).
If the turbidity sensor fails, the machine as-
sumes the water is “very cloudy”, which results
in a longer program time, prewashes, additional
rinses and so on.
The turbidity meter is located at the front edge
of the bottom drain.
Humidity sensor
The humidity sensor is located in the fan
house. The sensor is of the capacitive type
and measures relative humidity. The humid-
ity sensor measures the ambient humidity
before the drying process begins. The drying
process continues until the humidity sensor
detects a level slightly above ambient humid-
ity (min. time 30 min. and max. time 70 min.).
