GENERAL
Spirit User manual page 2
Designation
This manual applies to the Spirit 2-group (Duette) and 3-group (Triplette) espresso machines with
touchpad or Bastone operation manufactured by Kees van der Westen Espressonistic Works B.V.
Separate rotational pumps with electric motors are part of the appliance.
Precaution
Hot surfaces!
Parts of the machine will be hot when the machine is turned ON.
•The cup tray can reach temperatures up to 65°C.
•The metal groups are intended to radiate heat and can reach a set-temperature of up to 99°C.
Hot water and/or steam!
When the machine is heated up, hot water and steam can escape from various parts of the machine
upon manipulation of a corresponding interface (valve, switch, touch-button, …).
•Activating the group will lead to water being dispensed with a temperature of up to 99°C.
•Activation of the hot water dispense can lead to steam escaping with temperatures up to 130°C as
well.
•Activating the mix-water dispense can lead to overheated water (steam) being dispensed when
the cold-water addition is not set correctly.
•Opening the steam tap will start steam escaping from the steam wand-tips, the steam can reach
temperatures up to 130°C.
Safe operation
•The espresso machine needs to be installed with the feet at a height of 95-100 cm above the floor.
•The espresso machine has to be placed in a horizontal position on a sturdy and flat surface.
•If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or
similarly qualified persons in order to avoid a hazard.
•The new hose-sets supplied with the appliance are to be used. Old hose-sets should not be
reused.
•Intended use of the appliance is restricted to well-trained personnel only.
•The appliance must be installed in locations where it can be overseen by trained personnel.
•The appliance may not be left unattended when there is the possibility that children and/or
vulnerable people can reach the machine.
•This appliance can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been
given supervision or instruction concerning use of the appliance in a safe way and understand the
hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall
not be made by children without supervision.
•The mains electricity the appliance is connected to must include a residual-current-circuit-breaker
of 30 mA.
•The appliance may not be cleaned with the aid of a water jet.
•The appliance is not suited for outdoor use.
•Ambient temperature for correct operation of the appliance is 10-30°C (50-86°F).
•If ambient temperature falls below 5°C (41°F), keep the machine at ECO or ON to prevent freezing
of water inside the machine.
Note that the external rotational pump should be kept above freezing point of water as well.
Whenever the machine and/or pump have suffered freezing conditions, ask a technician to start-
up the appliance again.
•It is advised to install a leak prevention system as the appliances is directly connected to the water
mains. An unattended leak can cause serious damage to the premises.

Water Quality
Have a water treatment system installed and its function checked regularly. The treatment system
should at least have a carbon block that not only traps drug-remnants, Chlorine and organic
compounds but also prevents rigid particles >30 μm to enter the pump. Optimally, the water fed into
the espresso machine would fall in the upper-right part of the SCA “core zone”, see Figure 1, and have
a pH of 7.0-7.5 (at 25°C).

Table 1. Showing parameter values for water meant to brew coffee with.
Water with properties that lie within the SCA “core zone”and has correct pH combines technical
aspects enabling a safe operation and sensory aspects yielding a high quality brew, provided the other
parameters are met as well. High brew-ratio’s, as for espresso, shift the optimum of total hardness and
alkalinity towards higher values within the core zone.

The conversion from electrical conductivity to TDS depends heavily on the water composition and temperature, yielding results
that can vary significantly. Additionally, even if the estimated TDS value is accurate, it does not contain any information about
what the TDS is actually made up of.

Mains switch
The mains switch (see Figure 3 a) is located at the right hand side of the machine and has 3 positions:
OFF All power to the machine is disconnected.
NO HEAT The machine is connected to power, but power to the heating elements is disconnected.
The machine functions but there is no heat and thus neither hot water nor steam
pressure. The lack of steam pressure means that flow from the hot water spout is less
than normal.
ON Machine and heating elements are connected to power.

Temperature controller switches
Each boiler is equipped with its own temperature controller and ON-OFF switch (see Figure 5) so that
you can engage and disengage the heating of any group individually, e.g. when business is slow.
You may also disengage the steam/hot water boiler heating if only espressos are made. However,
keep in mind that in this case the heat exchangers are immersed in cold water so that the water
flowing into the coffee boilers is not pre-heated. With high output, the coffee boiler heating element
(900 Watt) may not be able to keep up with the demand and brewing temperatures may fluctuate more
than when the steam boiler is engaged.
Figure 5. Showing the temperature controllers with their ON-OFF switches for the steam boiler and the
two groups on a Spirit Duette. Switches are in the OFF position with levers pointing down, displays are
unlit.
Volumetric stop of a brew
When water flows through a coffee group, the flow meter of that group sends pulses to the controller.
The controller counts the pulses after activation of the group and will de-activate the group when the
pre-set number of pulses has been received (that is when the pre-set volume of water is counted).
However, the amount of water that will end up in the cup may still vary considerably.
The next paragraph describes why a consistent volume programming procedure should be followed to
have …
Consistency in programmed volumes
Volumes should be programmed as if you are making a normal brew: with fresh coffee grinds
in the filter basket and a 2 second flush.
See next paragraphs for step-by-step instructions for touchpad and Bastone versions of the Spirit, the
description and explanation below is valid for all Spirits.
The machine must have been used for a few days before accurately repeatable volumes can be
programmed.
Programmed volumes mutate during a few days after installation as during first fill there will be an
inflow of about 2.5 litres of fresh water to each group. After a few days the excess air, which is always
present in tap water, has segregated and will be expelled from each group and air content in the
coffee-water is stabilised.
The machine must be completely warmed up and used to make coffee a few times per group.
Using the machine ensures that the drain trap contains some water (which may evaporate overnight
when the machine is not used but still warm).
Variance in coffee bed characteristics (ground coffee particle size and distribution and packing/
tamping) should be a small as possible.
You have to make sure that the coffee-bed during volume-programming is the same as during the day
(for that reason: do not use grinds that have been in a storage container if you normally use grinding-
on-demand; level and tamp the grinds as if to make an actual brew; …).

USER MANUAL
Spirit User manual page 7
The amount of water in the feed line from group-valve to coffee-bed should not vary.
When a brew is finished, excess pressure on the coffee-bed is released via the 3-way group valve at
the back of the coffee boiler neck. This line may or may not drain completely before a new shot is
started. To have initial conditions as identical as possible we recommend a short flush (2 seconds) just
before locking in the filter holder with new grinds such that conditions in the feed line before a brew is
started is always the same.
Flow rate during the entire brew may not fall outside the range of the flow meter.
At the start of a brew, when the coffee bed is dry, flow-rate in the coffee system is very high. Right
after the pre-infusion stage when the coffee is wetted and swollen up, flow-rate in the coffee system
drops dramatically, the more so with smaller grain-size and closer packing of the coffee-bed. As there
is no flow meter available that can accurately count volumes in a wide range from very slow to very
fast flow we install different flow meters for different preferred brews: 0.7mm aperture (3300 pulse/litre)
for short brews like ristrettos and espressos, 1.15mm aperture (2000 pulse/litre) for longer brews like
(double) lungos. A flow meter intended for short brews may not accurately count the volume of a long
brew and vice-versa. The flow meter is installed during assembly of the machine according to the wish
of the client but can be exchanged for another type later.
If brews are made with very fine and closely packed coffee grinds, the flow at the early stage of the
brew becomes so slow that volumes counted by the controller may still deviate from brew to brew
when the flow at any time during the brew becomes slower than 25 ml/minute (0.7mm flow meter) or
35 ml/minute (1.15mm flow meter) as the impeller in the flow meter will come to a stand-still or is
running too slowly. When an LED on the group starts flashing during the brew it is certain that the flow
is too slow but the blinking may hold off even when flow was too slow for accurate counting. When you
prefer to brew that slowly we advise to use scales under the cup in combination with manually (de-)
activating the group for best weight consistency in the cup.

Touchpad
Each group is operated by a touchpad and each touchpad has 5 buttons with internal LED’s (see
photo in Table 2). The left hand side touchpad has some functions which are not available on the
other touchpad(s).
ON-OFF
The upper button (larger circle) is an ON-OFF group switch with programming function.
Press this button briefly to open the group valve and activate the pump, the LED in the button will light
up. Press it briefly again to deactivate the pump and close the group valve, the LED will go off.

Table 2. Listing the functions of the 5-button touchpads.
Program brew volumes
During the programming phase of a group, all other groups, even hot water, remain disabled.
You can program up to 8 different volume doses in a Duette, and up to 12 different doses in a
Triplette.
Volumes should be programmed as if you are making a normal brew: with fresh coffee grinds
in the filter basket and a 2 second flush. Have a pre-filled and tamped portafilter ready.
1. Keep the upper button (#5) of the left hand touchpad pressed for 6 seconds (until the upper LEDs
of all touchpads start flashing) to enter the programming mode. You may now program any one of
the lower 4 buttons of any touchpad.
2. Press one of the lower 4 buttons briefly to activate the group, the LED in the selected button will
light up (the upper LEDs of all touchpads will also be lit) and press briefly again after 2 seconds
(this is the short flush). This flush-volume will temporarily be stored in the memory.
3. Quickly lock in the filter holder with coffee grinds and with the same button activate the group
again to start the brew (preferably within 4 seconds but before 25 seconds have passed).
4. When the desired volume for the selected button is reached, press the button briefly again. The
“dosing” LED will go off and the programmed volume for that button will replace the initially stored
flush-volume in the memory of the controller.
5. Within 25 seconds (as long as the indicator light is flashing): continue to program another volume
(other button on touchpad, or go to next group, repeat the 2 second flush just prior to locking in the
filter-holder with fresh grinds and start the actual brew), or …
6. Briefly press the upper button (#5), or wait 30 seconds (until the indicator lights dim) before
touching any lever or button, to exit the programming mode. You can re-start from 1 for another
volume to be programmed.

USER MANUAL
Spirit User manual page 9
Left hand rules
Attention! Programming the left hand group overrides the stored volumes of the other group(s). If you
want different volumes on each group, start by programming the left group (using the left hand
touchpad), then program the other group(s).
Program hot water timer
The left hand touchpad also governs the hot water timer. Programming is similar to dosing the coffee
buttons. Keep the top button (#5) on the left hand touchpad pressed until the upper LEDs of all
touchpads start flashing (about 6 seconds). Briefly press down the hot water lever (see Figure 3 b) to
start water flow. Press briefly again when the desired amount of hot water is reached. The controller
actually stores the amount of seconds between activation and de-activation of the hot water
distribution. Briefly press the top button (#5) again to exit the programming mode.
Start automatic back-flush program
See paragraph “Back flush group” on page 19 for complete back-flush procedure.
The left hand touchpad is also used to start the automatic back-flush program (see also
Table 2).
To start the back-flush program:
1. Switch machine “OFF”.
2. Press-hold the #4 button on the left touchpad, turn the mains switch to “NO HEAT” or “ON”.
3. The cleaning program pressurises and de-pressurises all groups simultaneously for 8 times in a
row.
4. As soon as the program has ended, the main controller will return to normal operation (provided
that the mains switch is in position “ON”). It may take a while for the boilers to reach the
programmed temperatures as a lot of cold water has flown into the system during back-flushing.
Note! The controller incorporates several functions which you may accidently address while trying to
start the automatic back-flush program.

Bastone
(bastone = Italian for stick)
The Bastone version is very similar to the touchpad version but the touchpads have been replaced by
Bastone units that include a brew lever, an indicator light, a push button and a toggle switch. The push
button underneath each brew lever is the continuous (ON-OFF) switch for that group. Each brew lever
can be configured to deliver 2 pre-set volumes according to the position of the toggle switch
underneath the push button. The indicator light will light up when the group is active, or flash when the
controller is in programming mode. A pre-set volume can be stopped before the volume is reached by
shortly pressing the brew lever again.
Figure 6 a (left). Components of the right hand side Bastone unit.
Figure 6 b (right). Functions of the different Bastone components.
Program brew volumes
During the programming phase of a group, all other groups, even hot water, remain disabled.
You can program up to 4 different volume doses in a Duette, and up to 6 different doses in a Triplette.
Volumes should be programmed as if you are making a normal brew: with fresh coffee grinds
in the filter basket and a 2 second flush. Have a pre-filled and tamped portafilter ready.
1. Keep the push button of the left group pressed for about 6 seconds (until the LEDs of all Bastones
start flashing) to enter the programming mode. You may now program any one of the volumes.
2. Press the brew lever briefly to activate the group (the LEDs of all Bastones will be lit) and press
shortly again after 2 seconds (the volume of this short flush will be temporarily stored in memory).
3. Quickly lock in the filter-holder with coffee grinds and activate the group again to start the brew.
(preferably within 4 seconds, but certainly not later than after 25 seconds)
4. When the desired volume for the selected group is reached, press the lever briefly again. This
latest volume for that group will overwrite the previously stored -flush- volume in the memory of
the controller.
5. Briefly press the push button switch, or wait 30 seconds (until the indicator lights dim) before
touching any lever or button, to exit the programming mode. You can re-start from 1 for another
volume to be programmed.
Left hand rules
Attention!When you program a volume for the left hand group, the other group(s) will copy this
volume. If you want the right (and, if present, middle) group to be programmed differently from the left
group, start by programming the left group, then program the other group(s).

4. Briefly press the push button switch or wait 30 seconds to store the programmed volume and exit
the programming mode (the indicator lights go dim).
Start automatic back-flush program
See paragraph “Back flush group” on page 19 for complete back-flush procedure.
1. Shut down machine by turning mains switch to “OFF”.
2. Make sure that the toggle switch under the left hand group is in the left position (see Figure 7).
3. While pressing the left group lever down, turn the mains switch to “NO HEAT” or “ON”.
4. The back-flush program will start (if it does not start, check position of toggle switch).
5. As soon as the program has ended, the main controller will return to normal operation (provided
that the mains switch is in position “ON”). It may take a while for the boilers to reach the
programmed temperatures as a lot of cold water has flown into the system during back-flushing.

Dispensing hot water
Place a cup under the hot water spout and press the hot water lever down briefly (see Figure 8). The
flow will stop when the pre-set time has elapsed, or when the lever is pressed down briefly again,
whichever comes first. An interrupted dispensing is not stored in the memory, pressing the hot water
lever again will start a new dispensing cycle.
Figure 8 (left) showing the hot water lever and spout.
Figure 9 (right). Showing the right hand side steam lever and wand (with protective cap on steam tip).
Steaming
The Spirit has two identical steam wands with solenoid valves activated by a lever on the front of the
machine (see Figure 9) and/or optional foot pedal on the floor. You may reduce the maximum steam
power of an individual steam wand by adjusting the horizontal handle adjacent to the cup warming tray
on top the machine (see Figure 10).
Close to its most downwards position, the steam valve lever will lock in position. Lifting the lever
upwards a little will unlock it so that it automatically returns to the rest position (steam valve closed).
Before steaming milk it is necessary to open the valve for a short while to purge water from the steam
wand and heat up the wand and valve. The purged water is condensate from steam coming in contact
with the cold tubing, valve and wand. Position the tip of the steam wand over the drip tray when
purging the condensate.
Directly after steaming milk, flush the steam wand with a little steam and clean the tip of the steam
wand with a damp cloth. For hygienic reasons, do not use this cloth for anything other than cleaning
the steam tip.
Set maximum steam power
The steam power handle operates a ball valve incorporated in the steam line (see Figure 10).
Changing the position of the handle will adjust the steam power at the steam tip. You cannot
completely close the steam power with the handle to protect the solenoid. Before adjusting the
maximum steam power, make sure that the machine is fully heated up.
It is advised not to decrease the steam power by reducing the steam pressure in the boiler (lower
boiler temperature), as this will reduce the amount of steam that can be produced.

Change boiler temperatures
The factory set operational temperatures of the boilers are 93 °C (coffee) and 125 °C (steam) (199 °F
and 257 °F) respectively. 125 °C is equivalent to approximately 1.35 Bar steam overpressure.
Switch boiler temperatures with Störk ST25-Eco controllers
Your machine is equipped with Störk ST25-Eco controllers which allow you to easily change the
temperature of the corresponding boiler to a second (lower) setpoint. This way you can save energy
during the night or set a coffee-boiler on “stand-by” during slow periods while preserving a relatively
short start-up time.
Figure 11. The Störk ST25-Eco controller. (Left) The lit indicator dot signifies that the heating element
is activated. (Right) the controller in ECO-mode.
Factory standard is that the second setpoint for a steam-boiler controller is 70 °C (158 °F) and for a
coffee-boiler controller 50 °C (122 °F), see Table 3. While the second setpoint is active, the display will
show “Eco” instead of the actual temperature in the boiler.

and buttons are used to increase and decrease the temperature.
4. Releasing all buttons will enforce the newly set temperature.
The operational temperatures can be set within the following ranges:
•Steam boiler: 0-130 °C (32-266 °F).
•Coffee boiler: 0-100 °C (32-212 °F).

Notes!
The temperature sensor of the steam-boiler is placed above the water-level for quick response to
steam withdrawal. At temperatures below 110 °C (230 °F) the sensor will not register a change in
(water) temperature quickly. For that reason, the steam-boiler temperature may be up to 6 °C higher
than the Eco-setpoint at the moment you switch from Eco to operational mode.
Do not adjust the temperature of the hot water dispense by changing the temperature of the steam/hot
water boiler.
You can adjust the hot water dispense temperature by changing the pressure of the steam/hot water
pump.
Brew pressure gauge
In Spirits from October 2016 onwards, the pressure gauge no longer displays the pressure inside the
coffee boiler but the pressure in the line at the exit of the group valve, thus the actual pressure on the
coffee bed.
Pressure gauge that shows pressure on the
coffee bed. When the group is inactive, the
pressure displayed is thus (very close to) 0.
This means that when the group is inactive (open connection between coffee-bed and drain) the
pressure gauge will display 0 bar. When brewing a shot the coffee-bed becomes less permeable after
wetting (pre-infusion stage) and pressure will rise until brew-pump pressure is reached (ideally 9 bar).
If 9 bar pressure is not reached during a normal brew, either the pump pressure is set too low, or the
coffee bed was not able to produce enough counter pressure (not enough coffee grinds, coffee grinds
too coarse, channelling in coffee bed during extraction, …), or the gauge is malfunctioning.
Checking opening pressure of expansion valve
You can check the opening pressure of the expansion valve of a group by first having a long flush
(about 20 seconds) then quickly locking in a blind filter and activating the group again. Pressure will
quickly rise to pump pressure and then the expansion of heating up the cold inflow of water will
increase the pressure inside the coffee system above pump-pressure. The gauge should reach a
maximum value between 11 bar and 13 bar and then remain constant. If the pressure rises above 13
bar, the expansion valve should be re-adjusted. If the pressure does not rise above pump-pressure,
the expansion valve may need adjustment or the one-way valve in that coffee-circuit may be
malfunctioning: call in a technician.

Set hot water temperature
Hot water from the steam/hot water boiler is mixed with some cold water before it is dispensed. Water
temperature at the hot water spout depends on the temperature and amount of the mixed-in cold
water. The temperature of the incoming water differs from place to place and possibly on season as
well. The amount of cold water inflow is related to the inflow pressure and can thus be adjusted by
changing the (outgoing) pressure of the steam/hot water boiler pump. Increasing the pump pressure
decreases the temperature at the spout and vice versa.
With incoming water temperature of approximately 10 °C (50 °F) and a steam/hot water boiler
temperature of 125 °C (257 °F) and a pump pressure of 8.5 Bar, the water at the hot water spout is
approximately 95 °C (203 °F).
Procedure
1. Wait for the machine to be completely warmed up: at least “ON” and heating for 25 minutes and
used (as if) to make coffee and dispense hot water at least 5 times over the last 5 minutes.
2. Get the main controller in adjusting mode (to get a long lasting flow of hot water):
Touchpad: press-hold the upper button on the left hand touchpad for 6 seconds;
Bastone: press-hold the programming button below the left group lever for 6 seconds.
3. Within 5 seconds, activate water dispensing by shortly pressing the hot water lever down. Water
will start flowing.
Note! Work swiftly: the boiler quickly empties when hot water is dispensed continuously.
4. Measure the temperature of the outflowing water with a quick-response temperature sensor* and
de-activate the hot water by shortly pressing the lever again. The water temperature should be
around 95 °C (203 °F).
5. See Figure 12. If the temperature is too low: decrease pump pressure of the steam/hot water
boiler pump (turn set screw counter-clockwise).
If the temperature is too high: increase pump pressure (turn set screw clockwise).
Figure 12. Adjust hot water temperature by changing the pump pressure of the steam boiler pump.
6. After adjusting the pump pressure, measure the temperature again.
7. When the required temperature is reached, re-set the hot water timer to the desired amount of
water (see section “program hot water timer”).
8. When the required temperature cannot be reached, the fixed restrictor in the mixblock can be
exchanged for one with a larger diameter (to obtain a lower temperature at equal pump pressure)
or smaller diameter (to obtain a higher temperature). Contact a qualified technician for this.
* If you do not have a quick response temperature sensor, decrease the pump pressure until
boiling water is flowing from the spout (flow will sputter instead of dispensing a calm flow). Then
increase the pump pressure a little until a calm flow is obtained.

Shot timers
The timers on top of each group (see Figure 13) measure the time in seconds that the corresponding
group valve is open and thus indicate the brew-time. As soon as the group valve opens the time is set
to zero and counting starts. The timer stops counting when the group valve is closed and the
measured time between opening and closing of the group valve is displayed until the group valve is
opened again.
The shot time gives an excellent indication of the brew process and can assist the trained barista to
refine that process.
Figure 13. The Spirit shot timers.
A pre-set amount of water will pass through the machine when the brew process is started. Pump
pressure and diameter of smallest duct in the set-up (generally the restrictor underneath the group-
valve) determine the “free flow” rate (the flow rate when no filter holder with coffee bed is locked in).
During the pre-infusion phase, the combination of pump pressure, size of the restrictor, optional Idro-
matic and the coffee bed characteristics determine flow rate onto the coffee bed. The starting pressure
in the coffee boiler may fluctuate between 9 and 13 Bar but has very minor influence.
During the extraction phase, it is mainly pump pressure and coffee bed characteristics that determine
the flow rate. Variables in the coffee bed are numerous, the most important depend on the grinder
(amount of coffee particles and particle size distribution) and the barista (levelling and tamping of
coffee and thus packing of particles). Other variables in the coffee bed are: roasting grade, freshness
and air humidity.
During “free flow” the timer gives an indication of the condition of the smallest restrictor in the
espresso machine which, depending on individual set-up, has an orifice of 0.5 –0.8 mm. With such
small openings, even a minor divergence can cause quite a large difference in free flow rate.
Production variances of the restrictors are known to cause a difference in free-flow “shot time”
between groups of up to 15%.
Notes!
Measuring the free flow time will only give a rough indication of (smallest) restrictor size and will give
no information about pre-infusion and/or extraction. Only with a filled and tamped filter holder in the
group can timing measurements be used to give information about pre-infusion and extraction phase.
During the extraction phase, the coffee-bed in the filter is completely dominant in terms of flow rate
and any production variations in restrictor sizes are completely swamped by the restrictive effect of the
coffee-bed.

Indicator lights
Two groups of indicator lights are found on the bottom of the electronics box, see Figure 14. The set
on the left hand side (3 lights) indicate if the steam boiler heating element gets power or not. The set
on the right consists of 2 (Duette) or 3 (Triplette) lights and indicate if the individual coffee-boiler
heating elements get power or not. If the machine is functioning correctly, the 3 lights on the left
(steam boiler heating) should always light up simultaneously, the lights on the right show more erratic
behaviour. All lights should be “in sync” with the indicator dot on the corresponding temperature
controller.
If there is a problem with the machine, these indicator lights help to determine possible causes.
Figure 14. The heating element indicator lights on a Spirit Duette, left indicator lights for the steam
boiler, right for the coffee boilers. The indicator dot on the left hand coffee boiler controller is lit and the
corresponding indicator light (left light of right set) as well. The indicator dot on the steam boiler
controller is lit, as are all steam boiler indicator lights (left set). The right coffee boiler controller is in
ECO mode and the indicator dot is not lit, the corresponding indicator light (utmost right light) is off.

Daily to weekly routine
Clean body
The outside of the machine can be cleaned with window cleaner in a hand spray flask in combination
with a soft, clean, cotton cloth. When the machine is turned “ON” it will be warm and you have to work
swiftly to prevent stripes: spray and immediately rub.
Resistant smudges on high gloss panels may be removed with silver polish and a soft cloth (these
surfaces scratch easily, even copper polish may leave marks).
Lift the drip tray grill from the machine and clean it with washing up liquid and a sponge.
Activate the groups (without filter holder locked in) or let the hot water run for a moment and use a
brush to push remains into the drain.
As often as needed (with regular use once every day), pour one teaspoon of coffee dissolving powder
into the drain and flush it with some hot water down the drain to prevent clogging of the drain hose.
Remove filter basket
Materials needed
•Group screen extractor (or back end of teaspoon)
Procedure
1. Remove the filter holder from the group.
2. Pry the filter basket from the filter holder (see Figure 15).
3. When remounting the filter basket, make sure the spring remains in the indentation of the filter
holder and grabs the basket.
Figure 15. Pry filter basket from filter holder with the group screen extractor.
Clean filter holder
Remove the filter basket from the filter holder and clean the filter basket with a little washing up liquid
and plastic scouring pad or firm brush. Soak the metal part of the filter holder for 10 minutes in a
solution of 1 tablespoon of coffee dissolving powder in 0.5 litre hot water. The plastic handle will
eventually disintegrate in this solution and should thus be kept out of the solution.
Caution! Never clean the filter holder in a dish washer as dish washer detergent will ruin it.

DAILY TO WEEKLY ROUTINE

Clean steam wand
Milk easily bakes to the hot inner and outer surfaces of the steam wand and tip. Therefore, the steam
wand and tip should be cleaned with a damp cloth directly after each use. Do not use this cloth for
anything else than the steam wand.
Note! Immediately after steaming milk you should purge the steam wand with a little steam. This will
prohibit milk creeping into the pipe, and even into the valve house, through so called capillary rise.
Flushing also prevents clogging of the 4 holes in the tip. In the event that clogging occurs, place the
end of the steam wand and tip for several minutes in a glass of hot water. The remains will soften and
can be wiped off easily. NEVER scrape, grind or cut the steam wand or tip since it leads to damage.
Back flush group
Back flushing cleans the group and conduits from coffee residue which influences the taste of the
extraction since fresh (hot) water is transported to the coffee bed through these parts. It is advised to
back flush the groups at least once a day and when the machine is intensively used several times per
day.
Note! The automatic cleaning program is best performed at the end of the day and is very useful as
there is no need to repeatedly engage-disengage each group individually. You should run the program
twice: first with cleaning powder, then rinse the blind filter baskets and run the program again without
cleaning powder. In this second run you quickly empty a blind filter in between pressurising of the
groups, when the groups have depressurised you do the same with the next group, etc.
Described next is the procedure for an individual group in which the other group(s) remain(s)
operational.
Materials needed
•Plastic group brush (included in shipment)
•Blind filter (looks like a filter basket but has no holes, included in shipment)
•Coffee dissolving powder (included in shipment)
•Group screen extractor (included in shipment, or back end of teaspoon)
Procedure
1. Remove filter holder and flush the group for approximately 5 seconds.
2. Clean the group screen and group seal with the plastic group brush.
3. Pry the filter basket (e.g. with the group screen extractor) from the filter holder (see Figure 15) and
replace it with the blind filter.
4. Scoop 1 teaspoon of coffee dissolving powder in the blind filter and lock the filter holder in the
group.
5. Activate the group until full 9 Bar pressure is reached, then de-activate the group.
6. Wait for approximately 3 seconds then activate the group again for approximately 5 seconds.
7. Repeat steps 5 and 6 eight times (wait 3 seconds, activate group 5 seconds), or use the automatic
back-flush program (see page 9 or 11).
8. Remove the filter holder from the group, clean the blind filter by flushing it under the tap, activate
the group for approximately 5 seconds to remove possible powder from the group screen.
9. Lock filter holder in group, activate pump for about 5 seconds, de-activate pump, remove filter
holder and pour out remaining liquids.
10. Repeat step 9 four times (or use the automatic back-flush program).
11. Pry the blind filter from the filter holder and replace the filter basket.
Warning! Finishing the back flush routine without cleaning powder is essential to prevent remnants
of cleaning powder settling between the plunger and housing of the 3-way group valve.
