INTRODUCTION
Aim of this manual
This manual aims to explain in a clear and simple way the phases a Service Engineer
should follow to solve problems highlighted by the different alarm codes in EWM2000
electronic appliances with electronic control.
Operating procedure
1. Find the type of control involved by checking the summary at page V.
2. Every user interface is connected with a summary table of the operations necessary to
read the possible alarms, to access the diagnostic cycle and to configurate the main
electronic board (see column "Diagnostic Table").
3. Read the memorized alarm and consult the relative information (see "alarm codes",
from page 8.1).
4. Delete memorized alarm.
5. If you cannot access the diagnostic cycle, consult chapter "No access to diagnostic
cycle" (page 7.1).
6. In case of replacement of main PCB check if there are burn marks (see page 13.1-
13.2)
7. After every replacing of the main electronic board, you need to configurate the module.
You can find further information about the configuration code at page 10.1
("configuration code").
8. After every operation, check the functioning of the appliance through the diagnostic
cycle. For further information see page 6.1 (diagnostic cycle phases)
9. (Delete memorized alarm).

ACCESS TO THE To access the diagnostics system:
DIAGNOSTICS switch off the appliance and turn the programme selector knob
to RESET
press the START/PAUSE button together with one of the other
buttons and then, holding down both buttons, press the
ON/OFF button to switch on the appliance.
hold both buttons down until the buzzer (if featured) sounds and
the LEDs begin to flash (about 4 seconds)
Correct operation of all the components in the appliance can be
checked by turning the programme selector knob clockwise.
1. Operation of the user interface (step 0, page 6.1)
DIAGNOSTIC CYCLE
2. Water fill to wash compartment (step 1, page 6.1)
3. Water fill to pre-wash compartment (step 2, page 6.1)
4. Water fill to conditioner compartment (step 3, page 6.1)
5. Hot water fill or fill to bleach compartment (certain models only)
(step 4, page 6.1)
6. Heating and, in Jetsystem models, recirculation (step 5, page
6.1)
7. Check for leaks from tub (step 6, page 6.1)
8. Drain and spin, check for pressure switch congruency (step 7,
page 6.1)
9. Drying (washer/dryers only) (step 8, page 6.1)
To read the last alarm condition, after accessing the diagnostics
system:
turn the programme selector knob two positions counter-
clockwise from the RESET position (23 o 11).
ALARMS
Cancelling the last alarm condition
press START/PAUSE button and no. 6 button at the same time
during the course of the diagnostic cycle (2÷9).
The alarm is cancelled also when a new configuration is given to
the main PCB.
To access the machine configuration procedure, first enter the
diagnostics system, and then:
CONFIGURATION OF THE MAIN PCB
turn the programme selector one position counter-clockwise; the
display window shows the code relative to the position of the
programme selector and, after two seconds, the code relative to
the first of the 16 digits of the configuration code (position 0).
when one of the option buttons is pressed (with the exception of
the START/PAUSE button), all the digits which make up the
configuration code are displayed in sequence.
press the START/PAUSE button to modify the configuration
code (digit by digit).
when all 16 digits have been entered, check that the code is
correct, then memorize the code by pressing the
START/PAUSE button and one of the option buttons at the
same time; these buttons should be held down until the buzzer
(if featured) sounds.
EXITING THE
DIAGNOSTIC
To exit the diagnostic cycle, switch the appliance off, on, and
then off again.
