3. Service Functions

3.1 Service Tips

These models are equipped with Service functions
which help service technicians diagnose the machine
and find issues more easily and directly.

The Service functions include:

• Error code read out: The error codes of the last 3
errors shall be displayed

• Actuator Test: The actuators can be turned on
one-by-one

• LED Test: The test turns on all LEDs and the
display on the panel. Also, this test will erase all
saved error codes

• Functional Test Cycle: A short wash cycle which
involves all actuators

When diagnosing a machine, it is recommended that
the service technician should follow these steps in
order:

Step 1: Run the Error code read out. Record the 3 error
codes and look up their meanings.

Step 2: Run the Actuator Test. Pay attention to the
actuators which relate to the errors found in Step 1.

Step 3: Run the LED Test. The saved error codes will
be erased during this test.

Step 4: Run a test cycle.

Step 5: Run the Error code read out again.

If necessary, repeat the steps.

3.2 Location of LEDs and Buttons

There are only 3 buttons involved in the service
function test. For all models in the Durham range,
the first 3 buttons from the left are used for input. The
output of the service functions are shown by the LEDs
above these 3 buttons and in the display.

For models not equipped with a display, 2 additional
LEDs on the right-hand-side of the control panel are
used for output.

3.3 Program Presentation Mode

3.5 Error Code Read Out

The Service mode shall only be accessible from
the Program Preparation Mode. The machine is in
the Program Preparation Mode when a program is
selected but not started.

If the machine is not in the Program Preparation
Mode, pressing the CANCEL button will bring the
machine into this mode.

Pressing the CANCEL button may start the 1-minute
draining cycle. If this happens, close the door and
wait. Open the door at the end of the draining cycle
and the machine will be in the Program Preparation
Mode.

3.4 Access Service Mode

In all models in the Durham range, the full function
Service Mode includes:

• Error code read out

• Actuator Test

• LED Test

• Functional Test Cycle

According to hardware configuration of the
dishwasher and the marketing requirements, Service
Mode may vary in individual models and can be a
subset of the above listed functions.

To access Service Mode, make sure the machine is in
the Program Preparation Mode, press and hold K1and
K3, simultaneously for at least 5 seconds. The LEDs
L1, L2 and L3 blinks to indicate the Service Mode is
accessed. All other LEDs and the display (if equipped)
are OFF.

Machine is now in the Service Menu Mode. This mode
can be exit by pressing the CANCEL button, or 60
seconds after the last button is pressed.

After accessing the Service mode (L1, L2 and L3
blinking):

1. Press button K1 to show the first error code.

• L1 blinks to indicate the machine is in the Error
Code Reading Mode.

• The first error code saved in memory is
shown in the display if the model has a

display. If the model is not equipped with a
display, the error code is shown by the LEDs
L4 and L5. Details of the error code are listed
in the Error Codes section of this document.

2. Pressing button K1 again will show the second
error code.

3. Pressing button K1 once more will show the third
error code.

4. The Error Code Reading Mode shall exit by
pressing the CANCEL button or waiting 60
seconds after the last button is pressed.

3.6 Actuator Test

When the machine is in the Error Code Reading Mode
and showing the third error code, pressing K1 again
will switch the dishwasher into Actuator Test Mode.

1. Press button K1 for the fourth time to move into
the Actuator Test Mode. Pressing the button K1
repeatedly will sequentially activate one actuator
at a time.

• L1 will turn off. L2 will blink to indicate the

machine is in the Actuator Test Mode.

• The activated actuator number is shown in

the display, if the model has a display. If the
model is not equipped with a display, the
actuator number is shown by the number
of blinks of L4. For example, the actuator
number 5 will cause L4 to flash a total of 5
times, pause, then repeat this. The following
table provides the actuator details:

9

NUMBER OF K1 PRESSED ACTUATOR COMMENT

5 Drain Pump

6 Inlet Valve Off when water level is reached

7 Heater On only if water level is reached

8 Wash Pump

9 Dispenser

2. Pressing the button K1 when the actuator number 10 is activated will cause the machine to cycle back to
Error Code Reading and show the first error code saved in memory.

3. The Actuator Test Mode will exit by pressing the CANCEL button or waiting 60 seconds after the last button
is pressed.

3.7 LED Test

After accessing the Service Mode (L1, L2 and L3 blinking):

1. Pressing the button K2 will start the following function.

• All used LEDS and display (digits show “8:88”) blinks 5 seconds on 1 second off.

• If a buzzer is equipped, it will beep for 5 seconds.

• The error codes saved in memory are erased.

2. The LED Test mode shall exit by pressing the CANCEL button, or waiting 60 seconds after the last button is
pressed.

3.8 Functional Test Cycle

After accessing the Service Mode (L1, L2 and L3 blinking):

1. Pressing the button K3 will start the Functional Test Cycle. The cycle will not start if the door is open.

• L3 will blink for the duration of the cycle.

• The display will show the remaining time of the cycle.

2. The test cycle runs as a normal wash cycle. It shall be cancelled by pressing the CANCEL button or by
allowing the Functional Test Cycle to run to its end.

4. Error Codes

4.1 Error Management

In Durham range, the error codes are defined in
families of errors and current errors, displayed as:

iXY

i = error indication

X = family of the error

Y = current error

4.2 Display of Error Codes

The complete error code will be stored among the
three errors that can be stored by the appliance. A
new error code is only stored if it differs from the last
one stored. The three most recent error codes can be
displayed only in Service Mode or using the Sidekick
tool.

Only the error family codes are displayed to the user.
The complete error codes are displayed in Service
Mode.

Appliances with a display will show the complete
error codes as above format.

Appliances without a display (EDW4905 and
EDW5905) will show the error codes by a number of
flashes of 2 indicator LEDs (L4 and L5). The number to
flashing of the left-hand-side LED (L4) displays family
code and the right-hand-side LED (L5) displays the
current error. For example, error code i41 = L4 flashes
4 times… L5 flashes once… L4 flashes 4 times… L5
flashes once…

cycle resumes. The “i00” alarm is also deleted.

The flow controller controls the water flow towards the dishwasher spray arms.

The flow controller is designed to control the water flow towards the top spray arm only, bottom spray arm only
or towards both spray arms.

5.15 Smart Sensor Technology

• The Smart Sensor Technology:

• Washes the dishes and detaches the dirt
continuously

• In this way the turbidity sensor can detect
the degree of dirtiness and will define, if
additional rinses are necessary.

• The measurements will be done continuously
during the cycle.

• Temperature, water consumption and duration is
adjusted to the degree of dirtiness.

5.16 Dispenser

The new dispenser includes the following features:

• Low voltage driving - 5VDC => Safety
improvement

• Multiple dosage => Performance/Quality
improvement

• Sliding lid => Performance/Quality improvement

5.17 Multi Dosage - Specification

• PERFORMANCE

The dosage of the rinse-aid has to be independent of
the filling status of the container, as long as the refill
indication is not reached. After indicating the refill
minimum for another 2 dosage cycles, the nominal
volume has to be guaranteed.

Dosage Procedure – Multiple Dosage

The first activation impulse opens the detergent lid; no
rinse aid should be dosed into the tub.

With each further activation impulse a dosage volume
of 1.5 ml has to be dosed into the tub.
