Scale Removal - DeLonghi BCO110 Owner's Instructions Manual

• 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.

SCALE REMOVAL

The scale contained in the water, over time, will
cause plugging up of some elements in the appli-
ance and will thereby compromise its correct func-
tioning. The result will be that more time is
required to make coffee. The formation of scale
depends on the hardness of the water and on how
much the coffee maker has been used. To achieve
the best performance, descaling must be carried
out every so often. The coffee maker has a built-in
system that counts the number of cups of coffee
that have been made. The ON DRIP pilot light will
begin to blink when it is time to carry out descal-
ing. To do so, proceed as follows:
• remove the anti-chlorine filter (if present) and the
permanent filter from the coffee maker (so as not
to bathe them with vinegar)
• Dissolve 2 dessert spoons (about 30 grams) of
citric acid (available in pharmacies) in the
water;
• Place the container on the heating plate;
• Press the DRIP/AUTO button twice, allow
the equivalent of two cups to percolate and then
turn off the appliance;
• Allow the solution to sit for an hour;
• Turn the appliance back on and allow the rest of
the solution to percolate;
• Rinse by allowing the coffee maker to operate
with only water at least three times (1 full con-
tainer each time).
• Press the PROG and
simultaneously to reset the counter to zero.
IMPORTANT: if the machine is left unconnected to
the electrical mains for over two months, before
using it again it is necessary to carry out the
process of scale removal as described in the pre-
ceding section.
