Setting Pump Pressure On Older Models
The older machines have a different style expansion valve which
requires removing the outer shell. The old style expansion valve
will be located on the bottom of the boiler and may be positioned
facing up or down as shown to the right. The adjustment nut is the
one that is attached to the soft silicone hose and is shown in the
picture to the lower left.
To set the pump pressure turn the adjustment
nut shown in the picture to the left.
Turning clockwise will increase the pressure,
counter clockwise to decrease.
Be sure the attached silicone line does not get
twisted or this can cause the pressure to rise.
Group Gasket And Shower Screen Replacement
The group gasket is a black rubber gasket that makes the seal between the portafilter
and the group head. We recommend replacing the gasket on a yearly basis which will
make the replacement procedure much easier. The Alexia uses an E61 8.5mm gasket.
They can be purchased from our website at the link below.

Replacing the group gasket requires the removal of the shower screen as well so we
also recommend replacing the shower screen at the same time. The E61 shower screen
can be purchased from our website at the link below.

If water is leaking around the portafilter while brewing then the group gasket should be
replaced.
Before replacing the group gasket and shower screen the machine should be turned off
and cooled down so that the grouphead is cool to the touch.
