MAINTENANCE
WARNING
SWITCH OFF THE ELECTRIC SUPPLY (04) BEFORE PROCEEDING WITH THE USER'S
MAINTENANCE. IT IS RECOMMENDED TO CLEAN THE BOILER ONLY WHEN THE MACHINE
HAS COOLED DOWN (SWITCHED OFF FOR AT LEAST 5 HOURS).
8.1 MAINTENANCE OF THE STEAM GENERATOR
ELIMINATION OF SCALE DEPOSITS FROM THE BOILER
The unit is equipped with a maintenance warning which is working by writing
CALC
on the display
alternatively with the visualized temperature.
When the sign lights up it is possible to finish the cleaning task, then disconnect the power plug and
let the appliance cool down for at least 5 hours
.
It is essential to follow the above procedure to make sure that steam under pressure is no
longer present inside the machine.
(we suggest to proceed with the boiler cleaning prior to the
next usage of the machine provided that minimum 5 hours have been passed after having
disconnected the power plug.)
Put a basin under the unit and remove the underlying boiler drain cap (05), wait until the boiler is
completely emptied and insert the cap again only once you have removed eventual deposits from it
with running water as they may cause water leakages during the usage.
The cleaning process is finalized, insert again the power cord (04) into the electric power outlet and
switch the unit on by activating the general switch (03) and the buttons (07) and (08). We
recommend to activate also the switch (17A) on the steam hose and to press the safety switch (13)
to let out the air from the empty boiler.
Restore maintenance intervals CALC
Turn on the appliance by activating the switch (03) and the button (07), then again press the button
(07) and keep it pressed for approx. 10 seconds, the writing CALC will disappear from the display
and will only appear again for the next maintenance intervention.
The maintenance of the boiler is finished, proceed following the instruction described in chapter 7.
