De-scaling
The service life of your automatic
espresso machine will be lengthened if
you de-scale it regularly. To do this,
please use an environmentally friendly
de-scaling agent, and use it as stated
in the manufacturer's instructions.
When de-scaling, it is essential first
to unscrew the boiling sieve from
the boiling head with the aid of a
coin (Fig. 19).
0 First fill about half a litre of water
into the fresh water tank and then add
the de-scaling agent – never the
other way round!
0 Place a sufficiently large container in
the middle of the drip grill.
0 Allow about one-third of the de-scal-
ing agent and water to run through
the system by operating the appliance
as if you were making espresso (see
Section „Making espresso coffee").
Switch the appliance off again, and
leave the de-scaling agent to work in
for 10 or 15 minutes.
0 Then run the rest of it through the sys-
tem. It may be necessary to repeat the
de-scaling if the lime deposits are
heavy.
0 After the last cycle, run one or two
tankfuls of clear, fresh water through
the system to prevent the de-scaling
agent from having any affect on the
flavour of the espresso.
0 Then fit the boiling sieve back into the
boiling head.
Remark: Please do not use any pow-
dered de-scaling product!
What do I do if...
• the espresso temperature is too low?
– Run a boiling cycle but without any
espresso ground coffee before actu-
ally making espresso, and with the
sieve and carrier in position, in order
to pre-heat them.
– Tamp the espresso ground coffee
down a little more firmly.
– Pre-warm the cups.
– De-scale the appliance.
• the through-flow speed falls off
noticeably?
– Do not tamp the espresso ground
coffee down so firmly.
– De-scale the appliance.
– If the espresso ground coffee is too
finely ground it can block the
Crema-Plus sieve. If so, we recom-
mend the use of the problem-solving
sieve (Fig. 1/O).
• the espresso runs out at the side of the
sieve carrier?
– Make sure the sieve carrier is fitted
into the holding ring properly.
– Tighten the sieve carrier a little more
firmly into the holding ring.
– Clean the espresso ground coffee of
the edge of the sieve carrier.
– Clean the seal.
• no espresso comes out?
– Ensure that the fresh water tank is
full.
– Ensure that the fresh water tank is
properly fitted into position.
– Ensure that the sieve carrier is prop-
erly fitted into the holding ring.
– Do not tamp the espresso ground
coffee down so firmly.
– Move the steam lever to the „OFF"
setting.
– Clean the boiling sieve.
– De-scale the appliance.
