Replacing Portafilter Gasket
➡
vimeo.com/20084652 (password: prebrewpressure)
The portafilter gasket forms a seal between the portafilter and the grouphead,
preventing leaks. Over time, the portafilter gasket will become hard and lose its
seal. If it becomes difficult to insert the portafilter or if dripping occurs around
the portafilter body while brewing, replace the portafilter gasket.
Parts and tools:
•
Replacement 6mm portafilter gasket (part #46000-56091)
•
Flat-head screwdriver
•
Pick or awl
•
Cleaning brush or towel
Procedure:
1. Complete steps 1-3 of “General Group Cleaning” under “Grouphead”.
2. Use a pick or awl to remove the old portafilter gasket, pressing the
pick into the gasket and pulling downwards. If the gasket breaks into
small pieces, continue picking until the entire gasket has been
removed.
3. Insert new portafilter gasket in such a way that the flat side touches
the grouphead and the round side is visible from the bottom. Gently
press the gasket into place, then use a screwdriver, pick, or awl to
secure it in place.
4. Return the clean dispersion screw and screen to the grouphead.
‣
CAUTION: failure to reinstall the dispersion screw and screen
before next use may cause the grouphead to clog with coffee
particles. Do not attempt to brew espresso before the dispersion
screw and screen have been correctly installed.
