4. Service
4.1. Service Booklet
The service booklet is in each machine for information of maintenance done. It has space for breakdowns, which should
be noted down by the service technician.
4.1.1. Open machine
Open machine front: Open front cover, remove ground drawer and loosen screw
Remove side panels: Loose screws in the top cover plate. Then pull side panels upwards and remove.
4.2. Preventive Maintenance
Preventive maintenance ensures a continuous quality of products and reduces unscheduled breakdowns. During
preventive maintenance service will be done and necessary spare parts will be exchanged.
The bases for preventing maintenance are kits with all necessary parts. They are available as “Service kit” and
“Extension kit”.
The preventive maintenance is driven by the number of brewing cycles and/or the predefined time. Reaching the
number of cycles or the time, the coffee machine indicates the message "Perform the preventive maintenance".
We recommend adjusting the maximum brewing cycles to 40’000 cycles and the time to 1 year.
The brewing cycles depend on various criteria as regularity of brewing and cleanings, composition of water, cleaning
product, climatic conditions, etc.
In case of unfavorable conditions adjust the number of brewing cycles.

4.3. Grinder
4.3.1. Limit Grinder adjustment
The grinder adjustment from outside can be limited with the springs we deliver with the machine.
Make first the basic adjustment and then mount the spring as shown in the pictures to limit the grinder adjustment.
4.3.2. Block Grinder adjustment
To block the grinder adjustment, make first the grinder adjustment and then
turn on the blocking screw on the left and on the right inside the machine for
blocking the adjustment wheel.

Technical Manual V6.00 11 01.05.2017
4.3.3. Change Grinder burrs
A counter for the coffee is integrated in the software, which we recommend to set to 1000 kg. As soon as the amount is
reached, a message will inform to replace the burrs. The burrs should be replaced as well, when the grinding time
becomes noticeably longer or the grind becomes irregular.
-Close the bean hopper and grind the beans still in the grinder
-Switch off the machine
-Remove the bean hopper and the top plate
-Empty the grinder completely with a vacuum cleaner
-Remove the grinder adjustment from the grinder
-Turn the upper burr-holder counter-clockwise until the head emerges completely;
-Unscrew the screws and remove the burrs from the burr-holder:
-Carefully clean the burr supports, the burr-holder thread and its housing;
-Position the new burrs in their holders and block them firmly in place;
-Reassemble the machine, performing the previous steps in reverse.
-Switch on the machine
-Calibrate the new burrs.
4.3.4. SAG –Self adjusting Grinder
The grind setting will be managed according the brewing time of the coffee and not by the manual adjustment. This is
done with two motors with worm gear, which are mounted at the grinders.
To work with SAG, the extension board is a precondition as the calculation and the adjustment of the motors is managed
by the board. SAG is available as option for all machines of the Egro ONE Series.
When installing the machine, the grinder setting must be done as written in the installation manual. The parameter
<Product Setup> <Grinder> <SAG> <Module Type> has to be set to “Manual”.
When the grinder setting is finished you can activate SAG
SAG is working with a reference product for each grinder. Most time it is Espresso for the left grinder and coffee for the
right one. The parameters which have to be considered for the reference product are: grams, pulses, pre-infusion and
pressure. If for the left grinder product, no 3 “espresso” is selected, not only this product will be taken in account, but all
products, which have the same values for the above mentioned parameters, e.g. “Cappuccino”.
Take care at a BYO-machine that the reference products on the machine and on the tablet are the same.
The change of grinder burrs will be done the same way as described in the chapter above.

Technical Manual V6.00 12 01.05.2017
4.4. Brewing unit
4.4.1. Remove the brewing unit
Unlock the frame, remove left sheet metal, and disconnect the tubes from the pistons and the cables from the main
board. Unscrew fastening screws and disassemble brewing unit.
4.4.2. Remove the spindle motor
To remove the spindle motors, the screws at the top or at the bottom must be removed. Subsequently, the motor with
the piston are pulled out up or down and can be taken apart.
4.4.3. Brewing units
The Egro ONE has two generations of brewing units, which can be seen below. The main differences of the new one
(BC18) are the plastic parts for the funnel, the ejector and the ground slider. The brewing unit is fixed with screws on top
and bottom (BC18) and not with bolts (L61). The brewing chamber is fixed with openings and screws in the metal part.
L 61
BC18
4.4.4. Calibrating the brewing unit
When replacing the brewing unit (BC18) as well as the exchange of spindle motors, the brewing unit must be recalibrated.
The auto calibration can be found in <Machine setup> under the <Factory settings>.

Technical Manual V6.00 13 01.05.2017
4.5. Outlet
All machines have an outlet, which is manually adjustable in the height. This outlet has a handle to move the
outlet.
4.5.1. Adjust outlet
The outlet can be adjusted from the force you need to move.
4.5.2. Automatic outlet AS
The Automatic Spout (AS) is driven by a motor and offer the possibility to define five different cup heights,
which will be assigned to the products. This is also valid for hot water products, when the machine has a
central outlet.
If the machine has the hot water outlet on the side, the cup height must be defined as “top” so that no
movement takes place.
Machines with AS have no handle on the outlet. Anyhow it is possible, when needed, to move the outlet
slowly by hand.
This should only be done, if the outlet does not move anymore with the motor.

Technical Manual V6.00 14 01.05.2017
4.6. New milk system
4.6.1. Default values
The default values are considered as recommendations. As not all systems work the same, they might be adjusted. The
values are set for a milk temperature of 5°C.
The temperature setting “Medium” is to be used for foam products.
The higher the value of the milk temperature (low/medium/high) the more milk will be delivered. As the steam delivery is
constant the milk product will be cooler.
The higher the value of the foam structure (fine/medium/big) the more air will be pumped. By adding air, the
temperature of the milk products will increase.

4.6.2. Milk temperature
First, the milk temperature has to be adjusted. This is done in percentage of the power of the milk pump on the Top Milk
XP machines and with restrictors for the Quick Milk.
Please take care, that foam products always have a higher temperature than milk products with the same settings.
4.6.3. Foam structure
We recommend using only one temperature setting for foam products. This simplifies the setting of the foam structure
(in %). When changing the temperature setting the foam structure has to be adjusted.
4.6.4. Correction time
The correction time should be adjusted in a way that the milk reaches the frother head when the steam will be switched
on. This can be seen by a seriously increase of steam or by the switching of the steam valves.
If the correction time is too short, it could happen that after a rinsing no milk will be charged.
4.6.5. Change to pressure sensor
All configurations of the new milk system can work with a level measurement based on a pressure sensor. Order the
pressure sensor according to the single or double milk configuration of your system and follow the instruction given here
for each sensor.
For the sensor(s), an auto calibration is available and the technician can adjust it for the milk container in use at the customer.
-Remove the milk pump unit from the fridge
-Remove the tube from the white plastic part and take out the milk tube
-Remove the circlip and move the plastic part through the opening
-Insert the new plastic part with the mounted pressure sensor. The sensor with the red point on it is the standard
/left sensor, the blue point shows the right one, which is only used with two kind of milk.
Attention: Take care not to damage the cables and the sensor
-Secure the plastic part with the circlip and install the pump unit in the right place
-Plug in the milk tubes
-Connect the wires of each sensor together with the other sensor.
-Connect them to the mainboard of the coffee machine (connector J3)
-Make the auto calibration for each sensor.

Technical Manual V6.00 15 01.05.2017
The cable for the pressure sensor is done with two numbers:
10110976 Wiring pressure sensor NMS ONE (to connect with the machine)
10110835 Wiring pressure sensor NMS 1Milk (to connect with 1 pressure sensor)
10110839 Wiring pressure sensor NMS 2Milk (to connect with 2 pressure sensor)
When ordering the machine with KS9, the cable is in the fridge and has to be connected to J34 on the control board or to
J4 on the extension board, if it is in the machine.
When ordering the machine for FUM or SMPU the cable in the coffee machine is already mounted.
4.6.6. Milk level calibration
ATTENTION! Set <Product Setup/Milk/Module Type> first to “Fridge”.
The menu for the level measurement is in the software under Product Setup/Milk.
The machine has an automatic calibration, which allows the technician to adjust the milk container the customer is using.
The calibration should be done, when the machine is correctly positioned on a stable, leveled surface.
The auto calibration for the milk level guides with a sequence of steps through the procedure. It takes some minutes
depending on the capacity of the milk container. When the “Fill”-button appears, press it at least up to the point that the
metallic restrictor holder is completely in the water.
Attention, water is coming out of the outlet of the coffee machine!
As preparation take care that the milk tube is hanging free in the container and almost touch the bottom of it.
When having two machines, which take the milk out of the same container(s), take care to set the Zero level a little bit
higher to avoid that the products cannot be finished as both machine can take out milk at the same time.
Perform the auto calibration for both machines independently (not together).

Technical Manual V6.00 18 01.05.2017
4.6.8. Cold Milk Foam CMF
The milk system received additional components, to produce Cold Milk Foam (CMF).
This should be ordered with the machine, as a later retrofit is possible but very complex.
CMF is only available for Top Milk with one milk and one machine! All other versions cannot be equipped with
it.
At the rinsing and cleaning of the machine the way through the CMF-module will be considered, when a CMF-
product was produced before. Additional maintenance work is not necessary for the CMF-module.
Cold milk foam can have different stiffness. We integrated three levels with the following parameters:
Liquid
Creamy
Stiff
Milk pump
46%
44%
42%
Air pump
50%
50%
50%
Mixer
100%
100%
100%
The stiffness will be done mainly with the milk pump. Mixer and air-pump should not be adjusted.
If the retrofit with the CMF-module is planned, take care that the coffee machine must have the extension
board.

Technical Manual V6.00 19 01.05.2017
4.7. Old milk system
4.7.1. Adjusting milk temperature
The milk temperature will be adjusted by the flow. If the requested temperature is not reached, restrictors can be used.
Restrictors for cool box are available in Ø 1.1 –2 mm. Check steam pressure, if necessary.

When the refrigerator is placed under the counter a restrictor (0.4mm) has to be added to the air pipe between the fridge
and the coffee machine. The restriction can be placed anywhere on the air pipe; however, we suggest to put it in the
junction between the coffee machine and the fridge, which is easy to reach.
With this modification, the fridge works successful even with milk pipes of more than 1.5m.
Without this restriction, the milk pipes might not be emptied completely by the system after the automatic water rinsing and
so the first milk product after the rinsing would show some water coming out of the spout before the milk arrives.
The settings have to be modified in < Product setup> <Milk>:
