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. The Duetto uses an E61 8.5mm gasket.

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.

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.

Gasket and Screen Removal

There are two ways to remove the group gasket and shower screen depending on how old they are. If you replace the gasket yearly then the first method shown is recommended. If the gasket is older and dried out then the second method shown will be necessary.

Method 1

In the picture to the right shows an indent that goes around the perimeter of the screen.

Insert either a flat blade screwdriver or a spoon into the indent and then carefully pry the gasket and screen down. You may have to do this on a few spots to remove them.
