9.9. E xpansion valve adjustment (pump pressure)
Beneath the front panel, near the spout of the
water/steam nozzle, there is a knob to adjust the valve.
Turning the knob regulates the pressure of the coffee
delivery pump. To adjust the pressure, do the following:

Fill the coffee holder with the correct degree and
quantity of ground coffee.

Attach the filter holder and start coffee delivery.

Wait until the pressure gauge displays a stable
pressure value and then turn the valve adjustment
knob.

Turn in a clockwise direction to lower the pressure
in the circuit and anti-clockwise to increase the
pressure in the circuit.
It is recommended to set the pressure in the circuit to
between 9 and 10 Bar.

been successfully saved.
By changing the adjustment of the expansion valve
(section 9.9), the dose
programmed may not be the same. It is recommended
to adjust the valve and the grind before programming
the doses.
