Foreword:
Carrying out the Self-diagnosis, resets the following parameters to the factory's settings:
•
Buzzer active
•
Softener's Water Hardness set Level to d3
(d4 in case of Digit aesthetics)
•
Suggested Washing Program: Universal
•
Set Degree of Soiling
(when present): Medium
Self-diagnosis can be resetted while running. For doing so, proceed as follows:
•
Until
phase H it's enough to power the Dishwasher OFF with the O/I button. In case
of presence of water in tank, it will be drained at the next use of the appliance.
•
From phase L onward, push and hold the Programs Selection Button
(or
the Button
P1)
for
3
seconds.
If
the
Dishwasher
features
a Program Selection
Knob, move the
Knob to
0
(reset) and wait for the end of the drain phase.
Should a trouble be encountered during the Self-diagnosis, the related Error Code will be
directly
displayed
on the LCD. When the LCD display is missing, the Error Code is warned
through the
4 Hz flashing Program's LED. To actually see the type of Error, it's necessary to
restart the Self-diagnosis. Error is displayed in the beginning, through a
1 Hz blinking of the
Program's LED: one blink
