Part 3 Cleaning and care
Regular cleaning is essential in order to ensure problem-free operation of the coffee
machine and to ensure optimum coffee quality. Cleaning is done only every 27days or
230brewing cycles for the small coffee machines. In order to prevent the brewer from
breaking if the brewing chamber becomes clogged, cleaning tablets with asponge
must be used.
During cleaning, the sponge swells up, thus ensuring adefined water flow rate in the
brewing chamber during cleaning.

the last cleaning.
3/2 Warm-up rinse/coffee system rinse
When switched on, awarm-up rinse is performed. The water quantity is 60ml. If
the hot water temperature in the hot water boiler is >70°C, awarm-up rinse is not
performed.
When the machine is switched off, acoffee system rinse is performed unless no
beverage was brewed since being switched on.
The warm-up rinse can be started manually by means of the customer-care menu to
warm up the brewing system.
3/3 Automatic milk system rinse Connect&Clean
The request to rinse the milk system is shown automatically in the display after
removing amilk beverage after 20minutes has passed.
The monitoring period begins when the last milk beverage is removed. If the preset
interval of 20minutes has passed without amilk beverage being removed again in
the meantime, the request to rinse the milk system appears in the display. At the
same time as the message is being displayed, the steam valve is opened twice for
0.5seconds. This serves to clean the elastomer nozzle (steam nozzle.)
Waiting time: 20minutes
Rinse water volume: 90ml pulsed
Pulse of steam: 1x 4s
The request for rinsing the milk system can be postponed by pressing the Cbutton.
When the machine is switched off, the milk system is automatically rinsed. If power
is lost or if the machine is switched off by aprogrammed timer, the milk system is
automatically rinsed the next time the machine is switched on.
