Group Gasket And Screen Installation
Step 3
With the gasket and screen in the portafilter,
press the portafilter into the group head as
shown. Apply equal upward pressure on the
portafilter so the gasket goes in evenly. Once
the gasket is up far enough then lock the
portafilter into the group head and turn as far
right as possible. Then remove the portafilter
and re-install the insert basket and then work
the gasket up further into the grouphead
using the portafilter with the basket installed.
If you are having trouble then remove the
portafilter and press the screen up further by
hand and then try using the portafilter again.
Maintenance Tip: Replacing the gasket on a yearly basis will make the replacement
procedure much easier. There are also benefits to having a new gasket. It will provide a
better seal for a better espresso extraction and it also enables you to be able to remove
the shower screen without ruining the gasket to provide for better cleaning which will
result in better tasting shots.
Descaling
Descaling is the process of running a descaling agent such as citric acid through the
machine to remove the accumulation of mineral deposits.
If you are using softened water then it should not be necessary to descale the machine.
Often times descaling can cause more problems than it solves. It can react to the
minerals and foam over ruining electrical components. If the solution is too strong it can
cause*the*chrome*plating*inside*the*group*to*flake*off*and*get*in*the*coffee*or*if*it’s*too*
weak it can dislodge minerals and cause a blockage. For liability reasons we strongly
discourage descaling and will not provide any instructions on the process.
