1.1
Working principle coffee making system
Put the ON/OFF switch to I to turn the appliance on. The display lights up and shows the standard
choices. Press one of the selection buttons and then the START-button.
The solenoid valve (fig.1E) opens and the cold water reservoir is filled to the maximum electrode (fig. 1A).
Then the solenoid valve closes and two of the three flow heating elements are switched on (fig. 1F). If the
maximum electrode (fig. 1A) is detached, the third element is switched on. This way of starting is called
SOFT START and is used to start the flow process more gently.
A number of seconds after the maximum electrode is detached, the solenoid valve opens again until the
water level has reached the maximum electrode again. The amount of water that has flowed in is
continuously measured by the flowmeter (fig. 1D). If the set amount of water is reached, the solenoid
valve closes and the water level drops. If the minimum electrode is detached, the flow heating element is
switched off and the leak out time becomes active. The coffee runs from the filter unit through the coffee
blender into the container where it is kept warm by the heating element (fig. 1G). The amount of coffee
can be measured using the gauge glass. The coffee can be poured into cups or jugs using the no-drip tap.

1.2
Descale indicator
The coffee maker is equipped with a descale indicator.
The local water hardness can be set in the settings menu.
Using the table in the user guide, the water hardness can be converted to a certain water volume after
which it must be descaled. If the set amount of water has flowed through the system a spanner symbol will
appear in the display and the system can be descaled at a suitable moment.
In the operator menu the user can easily see how far away from a descaling signal the machine is. The
coffee making system also has a separate descaling program that the user can execute by loading it.
1.3
Safety devices
The coffee making system comes with a swivel arm and container detector.
The following technical problems cause the system to be switched off. In that case an ERROR code report
appears in the display followed by 3 long beeps.
- The maximum level is not reached within 40 seconds of the brewing process being switched on.
- The flowmeter does not indicate whether or not the solenoid valve has been opened.
- The minimum electrode is interrupted during the brewing process.

Fig. 2 Working principle of the hot water system
2.1
Working principle hot water system
Put the ON/OFF switch to I to turn the appliance on. The display lights up and shows the standard
choices. Press the hot water system on/off button.
The solenoid valve (fig. 2D) is driven and the cold water reservoir is filled to the minimum electrode (fig.
2B) and keeps on filling for 30 more seconds. Depending on the setting, a flashing tap symbol or
temperature indication appears in the display. The heating element (fig. 2) is switched on. The second
element (fig. 2G ) is switched on after a delay of a few seconds.
When the temperature sensor (fig. 2E) measures a temperature that is 1°C off the temperature setting, the
first heating element (fig. 2G) is switched off again. When the set temperature is reached the second
heating element (fig. 2F) is switched off. The whole boiler is filled in small charges and heats (see Working
principle charge fill/heating system) until the maximum electrode (fig. 2A) is reached.
2.2
Draining hot water
The hot water can be drained using the hot water drainage tap. The water reservoir is automatically
refilled (in charges) and kept at temperature. The maximum electrode has a small filling delay so that the
electrode always has sufficient contact with the water. Also, when the electrode no longer in contact with
the water level, it will be refilled with a short delay.
01 / 2006 (rev 2)

ComBi-line service enclosure
2.3
Charge filling/heating system
The heating system works according to the so-called charge filling/heating system. This means that after a
drawing off a (large) quantity of hot water the boiler is not filled with cold water in one go, but in smaller
charges. The boiler fills for a maximum of 30 seconds with fresh water (approx. 0.75 litres). This water is
first heated to the set temperature. The boiler continues this 30 sec filling /heating cycle until the boiler is
completely full. Using this system enables the user to have (some) hot water again in a short time.
2.4
Switching on the continuous heating function
The hot water temperature can be changed in the settings menu. The maximum temperature that can be
set is 97°C. An extra feature is the 97+ setting. This heats the boiler for an extra period of time in order to
make better water for tea. If the 97+ continuous heating function is set, then the heating element (fig. 2F)
stops when 96° is reached. After the boiler water has reached 97°C the heating element (fig. 2G) keeps
on heating for an extra time period*, and then switches off.
*Continued heating CB5W = 50 seconds / CB10W + CB20W = 100 seconds (Continued heating times yet
to be confirmed)
The continuous heating function only starts working:
- after the last charge filling has occurred.
- if hot water has been drawn off and fresh water has been added.
WARNING
The hot water system moisture outlet can be found on the top of the column.
Steam can escape through this opening during normal heating and heating with the continuous heating
function (97+) switched on! Do not touch the moisture outlet. There is a danger of burning.
2.5
Switching on the temperature display
The tap symbol that appears in the display when the hot water system is switched on can be replaced by
the hot water temperature in the settings menu.
2.6
Descale indicator
The hot water system is equipped with a descale indicator.
The local water hardness can be set in the settings menu.
Using the table in the user guide, the water hardness can be converted to a certain water volume after
which it must be descaled. If the set amount of water has flowed through the system a spanner symbol will
appear in the display. The system can be descaled at a suitable moment.
In the settings menu the user can easily see haw far away from a descaling signal the system is. The hot
water system also has a separate descaling program that the user can execute by loading it.
2.7
Safety devices
The following technical problems cause the heating elements and the solenoid valve to be switched off
and an ERROR code report to appear in the display followed by 3 long beeps.
- When the solenoid valve is open for longer than is normally the case
- If the maximum level is not reached after 10 minutes of the hot water system being activated.
- When the temperature sensor gives an invalid value.
- When the heating elements stay on for longer than 20 minutes.
- When the minimum electrode is interrupted during the heating process.

JP1
An EPROM is considered from electric and physical point of view a very sensitive component. This
means that you have to take extra care of the following points when placing or replacing an
EPROM:
•
•
•
Take care for a good transport of possible ESD influences.
Notice the correct position of the EPROM (see notch at exclamation mark).
Store the EPROM in a ESD free package.
Every time you change EPROM or main board you have to load default settings in the
software !!!
Installation PP34a
•
•
In case a new main board PP34a is installed the jumper JP1 has to be closed (see arrow).
This jumper prevents the battery from getting low.
Avoid any kind of ESD.
