Automatic Cleaning And Descaling; Please Note Before And During The Automatic Maintenance Programmes - Miele CVA 7840 Operating And Installation Instructions

Automatic cleaning and descaling

Risk of damage from spilt cleaning
and descaling solution.
Sensitive surfaces and/or natural
floors can suffer damage.
One way to catch the cleaning and
descaling solution is to place the
maintenance container under the
central spout before switching off the
machine.
Clear up any spillages of cleaning
and descaling solution.
When handling a descaling cartridge
which has already been filled with
water, ensure that the descaling
solution does not come into contact
with sensitive surfaces.
The coffee machine features automatic
maintenance programmes for cleaning
the milk pipework and brew unit, and
for descaling the machine. For this, the
Miele cleaning and descaling cartridges
must be fitted in the coffee machine. If
both types of maintenance programme
are due to run on the same day,
automatic cleaning will always be
performed before automatic descaling
(total time: approx. 2.5 hours).
You can set the time for starting
cleaning and descaling via the
Maintenance Timer.
The coffee machine will automatically
determine the days when to carry out
automatic descaling based on the
usage pattern.
During automatic cleaning, the milk
pipework gets cleaned and/or the brew
unit gets degreased. The coffee
machine also determines the cleaning
solution concentration and the cleaning
80
programme type for automatic cleaning
based on the number and types of
drinks made.
If you do not make any drinks, the
automatic maintenance programmes
will not be started.
In order to run the automatic cleaning
programmes, a solution is prepared by
mixing water with the cleaning agent.
This solution is then pumped through
the coffee machine pipework. After the
defined activation phase, all the
solution is rinsed out of the pipework
and the machine can then be used as
normal for making drinks.
During automatic cleaning and
descaling, you will hear various noises
(e.g. rinsing noises) at frequent intervals
even though the machine is switched
off.
Please note before and during
the automatic maintenance
programmes:
The coffee machine must be ready to
use and the following conditions must
be met:
– Ready-to-use cleaning and descaling
cartridges are fitted.
– The coffee machine must not be
disconnected from the electricity
supply during the automatic
maintenance programmes.
– The drip tray, brew unit and central
spout are inserted.
– The water container is inserted and is
filled with water at least up to the
 mark.
