wash it carefully with warm water.

• Make sure that the three holes of the milk

frother, illustrated in fig. 28, are not plugged.
If necessary, clean the holes with a pin or nee-
dle and soaking the frother bit in warm water. 

• Clean the steam release tube carefully so as to

not get burned. 

• Screw the milk frothing bit back into place.

CLEANING AND MAINTENANCE

• Before beginning any cleaning or maintenance

operation, turn the machine off, remove the
plug from the electrical power source and let
the machine cool down.

• To clean the machine, do not use solvents or

abrasive detergents.  A soft damp cloth should
be used to clean the surfaces.

• Regularly clean the filter holder, the drip col-

lection pan, the hot water drip spout, and the
coffee pots.  Do not wash the filter holder in the
dish washer.

• Never immerse the machine in water:  it is an

electrical appliance.

• Check from time to time that the holes in the fil-

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 lime
from this water can accumulate with the passage
of time.  Lime deposits can compromise the proper
functioning of the appliance.
The 

espresso coffee machine

must be decalcified

every 2 to 6 months (depending on the hardness of
the water and the frequency of use) using white
wine vinegar.  Proceed as follows:
• Fill the coffee pot for espresso coffee with vine-

gar to level 4;

• Pour the vinegar into the hot water tank and

replace the plug;

• Attach the filter holder;
• Place the small coffee pot under the filter hold-

er;

• 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 coffee
pot.  Release some steam every so often by
turning the steam release knob.

• When the 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 in order
to remove every trace of vinegar left in the cir-
cuits.

The 

drip coffee machine 

must be decalcified every

90 cycles.  The lime removal can be done by using
the special lime remover solvents made for drip
coffee machines found on the market.
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.  Insert the tank into
the machine.

• Place the coffee pot onto the hot plate and the

filter holder on this without coffee;

• Press the ON/OFF drip coffee switch, perco-

late 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 percolate through the circuits;

• To rinse the appliance, operate the machine

with plain water and without using ground cof-
fee at least 3 more times (3 full tanks of water).

The repairs of the coffee machine due to mainte-
nance operations that haven’t been carried out,
such as lime removal etc. will not be covered by
warranty.
