Descaling
CAUTION
— damage to the machine due to limescale deposits
Limescale can damage the machine.
•
Descale the machine as soon as the machine indicates that
this is necessary
.
This increases its service life and saves energy.
• Do not use any descaling agents made on the basis of formic acid.
• Use a standard, liquid descaling agent suitable for coffee and
espresso machines. Other agents may damage materials in the
machine and/or have no effect.
The descaling process cannot be interrupted. If an interruption
nevertheless occurs during the descaling process (e.g. due to
a power outage), it must be completed the next time the machine
is switched on. The machine will not be able to brew coffee again
until the process is completed.
When the “Descale”
symbol appears on
the display, the machine
needs to be descaled.
Descale the machine within the next few days. Do not wait any longer,
otherwise so much limescale may build up that a descaling agent will
no longer have any effect.
Descaling takes about 15 minutes.
Do not leave the machine unattended during the descaling process.
Requirements:
The machine is switched on and ready for use.
1. Pull the water tank up
and out of the machine.
2. Pour a standard, liquid
descaling agent suitable for
coffee and espresso machines
into the empty water tank.
Pour in water up to the MAX
mark. Please observe the
manufacturer's instructions.
3. Reinsert the water tank
into the machine. Press it
down as far as it will go.
4. Place an empty container (with
a capacity of at least 500 ml)
under the coffee/milk spout.
Remove the drip tray if
necessary.
You will need
to empty the container
underneath several times
during the descaling
process.
