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.
This is general guidance for the part type, not a model-specific procedure. If the part does not fit without force, stop and recheck compatibility.

Customer reviews
Perfect fit for the sage bambino machine just a bit tight to turn into lock position with the baskets supplied. very well made and good value.
It’s works great but with the mesh that goes into the try to filter the coffee sometimes it comes out when taking it off the machine but other then that for the price it’s great
Fits the Sage Bambino! Excellent workmanship, but the filters are useless. I'll keep the original ones.
