Group Gasket And Screen Installation- continued
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
Chris’ Coffee Service does not recommend descaling by the end user.
Often times home descaling can cause more problems than it solves. Various home
descaling agents 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/warranty reasons we strongly discourage descaling and will not provide any
instructions on the process. Please seek a qualified service technician to properly descale
your machine.
