remove the filter holder (

12) from the 

group head (

11

) by moving it towards 

the left, empty the coffee grounds and 

repeat the steps described above.

Do not touch the group heads or 

the steam and hot water nozzles 

when the machine is in operation 

and do not place your hands 

under the group heads or pipes 

during delivery in order to avoid 

possible scalding. 

When the machine is new, the 

filter holder may not be aligned 

(perpendicular to the machine) as 

shown in Figure 5. However, this 

does not prevent the machine 

from working properly. After 

being used for a short time, the 

filter holder will gradually become 

settled in the correct position.

G = Position of the closed filter 

holder when the machine is new

H = Position of the closed filter 

holder after the machine has 

been in use for a short time.

•

Coffee should be ground 

just before it is used. Once 

ground, coffee loses its flavour 

very quickly. If the coffee is too 

coarsely ground, the coffee will be 

light coloured and weak without 

froth and if the coffee is too finely 

ground the espresso will be dark 

and strong with little froth.

•

Warm cups help maintain the 

coffee at the right temperature. 

We therefore recommended that 

before using them, you place the 

cups on the cup warmer shelf (

3), 

which will be warmed by the heat 

given off from the boiler.

•

The pump pressure can be read 

on the respective pressure gauge 

(

5) during delivery. 

•

The correct pressure for making 

coffee is 8/9 bar. 

5–2. BREWING PRESSURE PROFILING 

CONTROL 

•

The pressure gauge (

33) mounted on 

the group head, allows the brewing 

pressure profile of the espresso to be 

read.

•

This allows the user to make sure that 

the grinding, pressing and the amount 

of the coffee in the filter is correct. 

•

If the brewing pressure is lower than 

the pump calibration pressure (9 

bar factory setting), it means that 

the coffee has been ground too 

coarsely, that the coffee has not been 

compacted correctly, or the amount of 

coffee is insufficient.

•

The  LPSGEG03 models are also 

equipped with the BPPC (Brewing 

Pressure Profiling Control) system and 

relative lever (

34).

•

The “BPPC” adjustment lever (

33) 

allows you to modify the pressure 

exerted on the coffee in real time as it 

is being dispensed. 

•

To modify the pressure profile during 

brewing, move the adjustment lever 

(

34) to the right or left respectively 

to increase or decrease the pressure 

exerted (Fig. 4).

•

This allows you to control the coffee 

brewing process manually and to 

obtain the best possible result with 

every kind of coffee or blend.

If the adjustment lever (

34) is 

facing towards the right (as in Fig. 

5), the coffee brewing pressure 

will be the same as the pressure 

exerted by the pump (8-9 bar), 

seen on the relative pressure 

gauge (

5).

It is not recommended to close 

the adjustment lever completely 

as the gauge pressure would 

indicate 0 bar and delivery would
