MAINTENANCE
Steam ready 06D
CAUTION:
WE RECOMMEND CLEANING THE BOI-
LER ONLY AFTER THE APPLIANCE HAS COOLED
DOWN, i.e. IF IT WAS SWITCHED OFF AT LEAST 5
HOURS BEFOREHAND (WITH THE PLUG DISCON-
NECTED).
The True Temp Technology makes it possible to use
distilled or osmosis water in the Thermostar (contrary
to many other commonly available steam cleaners). It
is therefore not necessary to decalcify the appliance. If
you use calcium-free water and the maintenance dis-
play indicates “CALC”, you can simply switch off this
display (see *1).
The appliance is equipped with a maintenance alert
system which activates if “CALC” is displayed alterna-
ting with the temperature. You can continue to work if
this appears. Then disconnect the plug and allow the
appliance to cool down for at least 5 hours. Follow the
aforementioned steps to ensure that no steam or pres-
sure is present in the boiler interior.
1 Switch off the appliance. (Disconnect plug)
2 Fill water reservoir (1) with water.
3 Place a suitable small tub underneath the appliance
or position it on top of the kitchen sink and remove
the discharge cover (04) from under the appliance.
Allow all the water and calcium deposits to drain
from the boiler. Shake the appliance a little to com-
pletely remove all the calcium deposits.
4 Replace the discharge cover (04) and refi ll the appli-
ance with water (1).
5 Then switch on the appliance and allow the pump to
run for approx. 2 to 3 minutes until the water from
the bottom tank fi lls the boiler completely (until the
pump stops making noise). The appliance is now
ready to use again!
The boiler button/heater (06B) must remain off
during the entire decalcifi cation process. Do not
turn the machine upside down or calcium may
enter into the valves!
If you are using water with a high calcium con-
tent, it is recommended to refi ll the appliance
with water and repeat the aforementioned steps.
*1 RESETTING THE MAINTENANCE INTERVALS CALC
Switch on the appliance by pressing buttons (2) and (06A), then press and hold button (06A) for
approx. 10 seconds. “CALC” will not appear until the next time maintenance is due.
Hour counter
This appliance is equipped with two hour counters. In
order to read the number of hours, switch off the appli-
ance using button (06A) and then activate button (06F
and 06G). Pressing this button will alternatively show
the hours for counter 1 and/or 2.
