ter for espresso coffee are not obstructed. If
necessary, carefully clean the filter with hot
water, scrubbing with an abrasive pad.
DESCALING
If the water in your area is quite hard, the calcium
from this water can accumulate and reduce the
machine’s efficiency.
The espresso coffee machine must be decalcified
every 1-3 months (depending on the hardness of
the water and the frequency of use) using white
wine vinegar. Proceed as follows:
• Fill the carafe for espresso coffee with vinegar
to level 4 of the ‘water level’ side.
• Pour the vinegar into the steam boiler and
replace the cap.
• Attach the filter holder.
• Place the small carafe under the filter holder;
• Turn the machine on and position the Vario
System selector to the “LIGHT” position.
• After a few minutes, the hot vinegar will begin
to flow, through the filter holder, into the
carafe. Release some steam every so often by
turning the steam release knob.
• When all of the solution has gone through the
machine, turn off the appliance and let it cool
down.
• Repeat these operations at least two times
using clean water instead of vinegar to remove
every trace of vinegar left in the circuits.
The filter coffee machine must be decalcified every
40 cycles. Descaling can be done by using special
lime scale solvents made for filter coffee machines.
Alternatively, white wine vinegar can be used, fol-
lowing this procedure:
• Pour two cups of white wine vinegar and three
cups of water into the tank.
• Place the large carafe onto the hot plate but
leave the filter empty.
• Press the ON/OFF drip coffee switch, filter the
equivalent of a cup of the solution and then
turn off the appliance.
• Allow the vinegar to sit in the machine for an
hour.
• Turn the machine back on and allow the rest of
the solution to filter through the circuits.
• To rinse the appliance, operate the machine
with plain water and without using ground cof-
fee at least 3 times (3 full tanks of water).
