DESCALING THE BOILER (if present)
The appliance can count the functioning
hours of the steam generator and therefore
inform the operator when it is necessary to
activate de-scaling of the steam generator
via the special cycle
[dE]
.
When the appliance is switched off, the
display
7
shows the
[dE]
message and
display
9
shows the days missing until
recommended de-scaling of the boiler,
indicated by the
[dE End]
message.
NOTE:
Display
9
indicates the DAYS missing
until the appearance of the
[dE End]
message.
The message starts to appear 15 days
before the appearance of the
[dE End]
message.
The
[dE End]
message does not stop the
appliance definitively for obvious service
reasons. It is however recommended to
activate the
[dE]
program as soon as
possible after the appearance of the
[dE
End]
message.
To check the amount of hours missing until
the appearance of the
[dE End]
message,
with the appliance live and display off,
press button

. The display

shows
[USb]
,
turn knob

until

the knob to confirm the selection.
The display

shows
[P00]
, turn knob
8
until the display shows
[dE]
. The display
9
shows the hours missing until the
appearance of the
[dE End]
message.
The presence of scale causes loss of power
in the steam circuit and serious damage to
the steam generator.
Note that the steam generator runs a drain
and wash cycle automatically every day so
as to regenerate the water in it. Descaling
frequency is defined by several parameters
entered on the electronic card by the
technician at the time of installation on the
basis of the characteristics of the supply
water (upstream from the softener) and on
the basis of its technical characteristics.
The end of the
[dE] descaling
cycle permits
resetting the total number of hours and the
removal of the message: to permit this
operation, disconnect the oven from the
electric mains for a few seconds after the
end of the descaling program.
Descaling should be performed with the
appliance cold and clean (see
“Daily
Cleaning”
), preferably with the assistance
of the authorized technician.
