Installation guide - Fitting a portafilter
General guidance for this part type - always follow your device manual- No tools required
- A handle that turns past center or leaks usually means the group gasket is worn.
- Bottomless portafilters show channeling; a spraying shot points to uneven tamping, not a faulty part.
- 1Check the match. Confirm the group head size and the number of locking ears match the compatibility list on this page.
- 2Fit the basket. Press the filter basket into the portafilter until it sits flush; press in baskets snap in with thumb pressure.
- 3Insert it. Line up the ears with the slots in the group head and push up.
- 4Lock it. Turn the handle until it locks firmly, typically near perpendicular to the machine. Do not force it further.
- 5Run a blank shot. Run water only and check for drips around the rim.
