Descaling
Cleaning button
If the cleaning button stays lit up in red,
the machine needs to be descaled.
Do this within the next couple of days.
Do not wait any longer, otherwise so
much limescale may collect that a
descaling agent will no longer have any
effect.
Descaling takes approx. 30 minutes.
CAUTION — damage to the machine due to limescale deposits
• Descale the machine as soon as it indicates that this is necessary
(after approx. 50 litres).
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 can not be stopped. If the descaling process is
interrupted (e.g. due to a powercut), it must be completed immediately
once the machine is switched on again. The machine will not be able
to brew coffee again until the process is completed.
• If you do not descale the machine, then, until you do perform the descaling
procedure, the cleaning button will light up in red whenever you switch the
machine on.
• If you wish to perform an interim descaling (before the cleaning button lights
up in red), press the cleaning button several times until the button lights up in
red, then proceed as described.
Requirements:
The machine is switched on and ready for use.
1. Place a container with a capacity of
at least 600 ml under the beverage
spout.
You will need to empty the
container underneath several
times during the descaling
process.
2. Remove the water tank from the
machine.
3. Pour a standard, liquid descaling
agent suitable for coffee and
espresso machines into the empty
water tank.
Tip: We recommend using durgol
®
swiss espresso
®
descaler, which
is available from any Tchibo branch
and from specialist retailers.
Handle
4. Pour in water up to the handle.
5. Reinsert the water tank into the
machine.
