4. Service
4.1. Service Document
The service document for information of maintenance done, will be delivered with every machine. It has
space for breakdowns, which should be noted down by the service technician.
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 base for preventing maintenance are “Service kits”with all necessary parts.
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. Change Grinder burrs
A counter for the ground coffee is integrated in the software. We recommend to set to the counter in the
EgroTech App <Counter/Grinder/Ma. Value left> and <…/Max. Value right> to 1000 kg. As soon as the
amount is reached, a message will inform to replace the burrs.
-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.
If the grinding process takes an unusually long time, the grinder should be recalibrated. If the grinder during
the calibration takes more than 5 seconds to grind 10 grams of coffee, the burrs must be replaced.
If the grinding result is irregular, the burrs must also be checked and replaced if necessary.
4.3.2. SAG –Self adjusting Grinder
The grinder setting will be managed according the brewing time of the coffee. This is done with a motor
with worm gear mounted to the grinder.
All machines of Egro NEXT have SAG by default
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
pressure
If for the left grinder the product “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”.

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 control 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
Egro NEXT can be equipped with two different
brewing chambers –BC18 or BC22.
BC18 is the default brewing unit. It has the smaller
diameter of the brewing chamber and can work with
up to 18 gram of grind coffee.
4.4.4. Calibrating the brewing unit
When replacing the brewing unit or after the
exchange of spindle motors, the brewing unit must be
recalibrated.
The auto calibration can be found in <Machine setup>
under <Factory settings> of the EgroTech App. The
password can be found in the menu of EgroTech App.

4.5. Outlet
4.5.1. Manual outlet
This force, which is needed to adjust the outlet, is controlled
by a spring. To adjust the spring use an allen key on the two
screws on the backside of the outlet.
Move clockwise for stronger movement and to the opposite
direction for easier movement.
4.5.2. Automatic spout AS
The Automatic Spout (AS) is driven by a motor and offer the possibility to define five different cup heights
in the EgroTech app, which will be assigned to the products in the Egro UI.
The parameter cup height is also used for hot water products if the machine has a central outlet and should
be set up according to the cup used.
If the machine has the hot water outlet on the side, the cup height must be defined to “top” so that no
movement of the outlet 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.

4.6. 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 Egro NEXT TopMilk and with restrictors on the Egro NEXT QuickMilk.
Please take care, that foam products always have a higher temperature than milk products with the same
settings.
TopMilk
Milk temperature
High speed (Low milk temp.)
95
Medium speed (Medium milk temp.)
70
Low speed (High milk temp.)
57
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.
TopMilk & QuickMilk
Foam structure
Fine
33
Medium
38

4.6.4. Correction time
The correction time enlarges the milk delivery time for the the first product after the rinsing. This is
necessary as the milk pipes are empty. It 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 TopMilk configurations of the milk system can work with a level measurement based on a pressure
sensor.
For a retrofit the the pressure sensor level measurement, select in the Web Shop 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)
-Perform the auto calibration for each sensor.
When ordering the machine with KS9, the cable is in the fridge and has to be connected to J4 on the
extension board.
When ordering the machine for FUM (Fridge Under Machine) or SMPU (Standanlone Milk Pump Unit) the
cable in the coffee machine is already mounted.
4.6.6. Milk level calibration
ATTENTION! Set <Product Setup/Milk/Module Type> first to “TopMilk”or “TopMilk CMF”.
The menu for the level measurement is in the software under <Product Setup/Milk>.
The system with the pressure sensor must be correctly configured in order to be able to calculate the
available milk in the fridge.
The machine has an automatic calibration, which allows the technician to adjust the system to the milk
container in use.
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).

4.6.8. Cold Milk Foam CMF
Cold Milk Foam (CMF) is an option of the milk system, which should be ordered with the machine/fridge.
CMF is only available for Egro NEXT TopMilk with one milk and one machine! All other versions cannot be
equipped with it.
Special maintenance work is not necessary for the CMF-module. For the rinsing and cleaning of the milk
system the way through the CMF-module will be considered automatically, when a CMF-product was
delivered before.
Cold milk foam can have different stiffness. We integrated three levels with the following parameters:
Liquid
