The interior of the heat-retaining carafe
insert consists of high quality double-walled
glass with a vacuum in-between for better
insulation. Any streaks or bubble marks
inside the carafe looking like bubbles or
scratches do not affect its functional use nor
its heat-retaining ability.
In case the glass is damaged for one or
the other reason as mentioned below,
there is a risk that the glass carafe
implodes. This might happen quite some
time after the glass carafe has actually been
damaged.
∙ Therefore do not drink out of the carafe
and do not put your hand into it. Always
close the carafe with its screw cap. The
coffee can be poured out easily by half
a turn of the cap, without removing the
cap. Do not leave the vacuum carafe
unattended near where children may
reach it.
To prevent damage to the glass carafe:
∙ Avoid shocks and great differences in
temperature.
∙ Do not stir in the carafe, for example with
a metal spoon.
∙ Do not use hard brushes or abrasive
cleaning agents.
∙ Do not wipe the inside with a cloth. Dust
particles may cut the glass (similar to a
glass-cutter).
∙ Do not wash in a dishwasher.
∙ Do not use in a microwave oven.
Descaling
∙ Depending on the water quality (lime
content) in your area as well as the
frequency of use, all thermal household
appliances using hot water need
descaling (i.e. removal of lime deposits)
on a regular basis to warrant proper
functioning.
∙ Any warranty claim will be null and
void if the appliance malfunctions
because of insuffi cient descaling.
∙ A lengthening of the brewing time and
increased noise during brewing indicate
that descaling of the coffee maker has
become necessary.
∙ An excessive build-up of lime deposits is
very diffi cult to remove, even when strong
descaling agents are used. It may also
cause the brewing system to leak. We
therefore strongly recommend descaling
the appliance after each thirty to forty
brewing cycles. For descaling, a vinegar
solution may be used as follows:
∙ Mix 4-5 tablespoons of vinegar with the
indicated maximum amount of cold water.
∙ Pour the descaling solution into the water
container, insert a paper fi lter into the
fi lter holder without adding any ground
coffee as described in section Making
coffee, and let the appliance run through
one fi ltration cycle. Repeat the procedure
if necessary. During descaling, ensure
suffi cient ventilation and do not inhale any
vinegar vapours.
∙ To clean the appliance after descaling, let
it run through 2-3 fi ltration cycles using
clean water only.
∙ Do not pour descalers down enamel
sinks.
Cleaning and care
∙ Before cleaning the appliance, ensure it is
disconnected from the power supply and
has cooled down completely.
∙ To avoid the risk of electric shock, do not
clean the appliance with water and do not
immerse it in water. The appliance may be
