Cleaning and care
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 insufficient descaling.
∙ A lengthening of the brewing time,
increased noise during brewing or
residual water remaining in the container
indicate that descaling has become
necessary.
∙ An excessive build-up of lime deposits
is very difficult to remove, even when
strong descaling agents are used.
∙ After 100 brewing cycles, the display
shows Descale. The appliance needs
descaling as described below. Once
descaling is complete, the Descale
indicator goes out.
∙ Descaling must not be done right
away, but should be done soonest. The
Descale indicator may be cancelled by
simultaneously pressing and holding
the h and min buttons for around 3
seconds. A new reminder will be issued
only after a further 100 brewing cycles.
∙ Descaling may also be initiated at any
time prior to the Descale indicator
showing.

The descaling process
∙ For descaling, a vinegar solution may be
used as follows:
∙ Mix 80 ml of vinegar essence with the
indicated maximum amount of cold
water.
∙ Pour the descaling solution into the
water container. Insert a paper filter
without adding any ground coffee.
∙ Press the and PROG-buttons
simultaneously, keeping them pressed
for around 3 seconds. The display
shows Descale. The descaling cycle
starts. To ensure thorough descaling,
the water is heated in intervals.
∙ Switch the unit off once the descaling
solution has passed through the system
completely.
∙ Repeat the procedure if necessary.
∙ D uring descaling, ensure sufficient
ventilation and do not inhale any vinegar
vapours.
∙ To clean the appliance after descaling,
let it run through 2-3 filtration cycles
using clean water only.
∙ Do not pour descalers down enamel
sinks.
