5.5Empty water system

After every operation, some water remains in the coffee machine. Therefore the water system must be emptied

if the coffee machine will not be used for a long time

as antifreeze measure

for repairs and shipment.

1) Switch off coffee machine.

4)Press and hold button "small cup".

5)Switch the coffee machine on again.

6)Release button "small cup".

2)Remove water tank.

3)Place a beaker under the coffee out let.

Model Citiz & Co:

Only one core unit should be emptied at

the same time (danger of mains supply overload).

After this procedure, the coffee machine

will not be ready for approx. 10 min (until the thermoblock cools to below 100 °C ).

The pump starts to drain the water system and stops automatically.

The coffee buttons blink fast simulta neously.

7)After automatic stop, switch off the coffee machine.
