Automatic Cleaning And Descaling; What To Ensure Before And During Automatic Maintenance Programs - Miele CVA 7840 Operating And Installation Instructions

Risk of damage from spilled 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
main dispenser 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 programs for cleaning the
milk pipework and brew unit, and for
descaling the machine. For this, the
Miele Cleaning and Descaling
Cartridges must be inserted into the
coffee machine. If both types of
maintenance program are due to run on
the same day, automatic cleaning will
always be performed before automatic
descaling (total time:
approx. 35 minutes).
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.

Automatic cleaning and descaling

The coffee machine also determines the
cleaning-solution concentration and the
cleaning-program type for automatic
cleaning based on the number and
types of drinks made.
If you do not make any drinks, the
automatic maintenance programs will
not be started.
In order to run the automatic cleaning
programs, a solution is prepared by
mixing water with the cleaning agent.
This solution is then pumped through
the coffee-machine pipework. After the
defined holding time, 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.
What to ensure before and
during automatic maintenance
programs
The coffee machine must be ready to
use and the following conditions must
be met:
- Ready-to-use cleaning and descaling
cartridges are inserted.
- The coffee machine must not be
disconnected from the power supply
during the automatic maintenance
programs.
- The drip tray, brew unit, and central
spout are inserted.
