Introduction
You are holding the Service manual for the DW90 generation of dishwashers.
The DW90 dishwasher series is available in several different models. The DW Outdoor model,
that this guide is focusing on, is designed for outdoor use. The type designation is most important
when identifying a particular machine model. This information can be found on the serial number
plate on the right of the inside of the door, where the machine’s model designation is specified.
The first two digits of the serial number specify the year of manufacture
while the third and fourth digits specify the week of manufacture. The
remaining digits form the sequential number.
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.

Troubleshooting strategy
Troubleshooting is an important part of the service call, so we have drawn up a troubleshooting
strategy that describes, in broad terms and step by step, what you need to do to find and diagnose
faults arising in our machines.
• Ask the customer to describe the problem.
• Check whether the customer’s description matches the reported fault.
• Check that the machine is correctly installed:
- Electrical connection - Drainage
- Water connection - Machine correctly levelled
Fault
found?
Incorrect installation or external factors that affect performance and functionality (for
example, water pressure, electrical supply, drainage).
The machine operates normally. No deviations can be found. The customer probably
needs to be informed about proper use of the machine. If necessary, also inform the
customer about the warranty conditions and the fact that the customer will be charged
for the service call.
Yes
Open the service menu:
1. Check the settings
2. Run a test cycle
3. Note any fault codes
If the above actions do not uncover the fault:
• Conduct general troubleshooting. Use the documentation available at ServiceSaver
(service manuals, service memos, wiring diagrams and other documents).

Inlet valve
The inlet valve has an electrical connector
that is coded to ensure it is not mixed up. It is
fitted with a filter, which can be removed for
cleaning. Both single and safety valves are used
as inlet valves. The inlet valve contains a filter
to stop particles then a flow limiter to limit
the flow to a maximum of 4 L (1 gallon)/min.
It opens when the water pressure exceeds 0.3
bar (4.3 psi) and provides full flow at about 2
bar (29 psi). It has a pressure range of 0.3 bar
(4.3 psi) to 10 bar (145 psi). The inlet valve is
fitted to the air gap and can be replaced from
the rear of the machine.
Purpose: To ensure that the machine
is supplied with water for the different
dishwashing cycles.
Safety valve
The safety valve has two independent valve seats,
each controlled by a separate electromagnet.
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
line voltage (e.g., a 230 V valve = 2 x 115 V coils)
Single valve
The single valve comprises an electromagnet
and a valve seat.
Components and function description
Here we describe the function and
specification of the most important
components. Certain components are found
only in more highly specified machines or in
particular markets. See the Troubleshooting
section for fault and information codes.
CU, Control Unit
The CU, or Control Unit, is a unit that functions
as both a control panel and a logic component.
The control panel is fitted with a display and touch
buttons for selecting programs, options and Start/
Stop. The control panel is an integrated part of
the CU and cannot be replaced separately. The
logic component manages functions needed for
dishwashing programs and diagnosis. The CU
has an internal power supply for the logic. In the
event of a fault, the CU can diagnose a number of
components and functions and display fault codes.
To facilitate troubleshooting the service menu
includes a component diagnostics function, which
activates the outputs in a particular sequence.
Accelerometer
The control unit contains an accelerometer, a
sensor that senses position and acceleration. It
controls the touch buttons and the brightness
of the light. The accelerometer turns off at a
specific angle to avoid causing a distraction
when seen from the worktop. It is calibrated
when the door is closed.
If this symbol appears on the display
the door is not open enough. Open
the door until the display lights up.
