Filter Baskets for the Chefman CafeMaster Pro
- Size matches the 51mm Chefman CafeMaster Pro group.
- Compatibility inferred from size; not stated by the listing.
- The portafilter's ear/lug geometry appears proprietary to this Chefman group. Even a correctly-sized 51mm third-party bottomless or spouted portafilter may NOT lock into the brew head. Verify the exact ear/lug fit against this specific model before buying any replacement or upgrade portafilter, and prefer sellers with a returns policy.
- 51mm is a thin accessory ecosystem to begin with; many '51mm' listings are cut for DeLonghi/Dedica groups and are not guaranteed to index into a Chefman group even at the same diameter. Confirm the part is fitted to this Chefman, not just to a 51mm DeLonghi, before buying.
- We analyzed manufacturer specs and could not confirm a user-removable shower screen, so screen-swap accessories should be treated as unverified for this machine.
- Skip machine-specific 'bottomless portafilter' purchases until you have physically verified the ear fit; a mismatch here is the most likely and most expensive wrong buy.
- Dose range 14-18g - match it to your grinder output.
- What size to buy
- Buy 51mm for the Chefman CafeMaster Pro.
- What to avoid
- Avoid 54mm and 58mm filter baskets - they will not fit the 51mm group.
- If you own another machine
- Own a Breville Bambino? Use the 54mm page instead - these 51mm parts will not fit it.

Before buying filter baskets
Does any 51mm filter basket fit the Chefman CafeMaster Pro?
No. The nominal size is only the first check. Model-specific locking geometry, basket depth, mounting pattern, or clearance may also matter. The portafilter's ear/lug geometry appears proprietary to this Chefman group. Even a correctly-sized 51mm third-party bottomless or spouted portafilter may NOT lock into the brew head. Verify the exact ear/lug fit against this specific model before buying any replacement or upgrade portafilter, and prefer sellers with a returns policy.
Is a filter basket the first upgrade to buy?
Not automatically. The Chefman CafeMaster Pro's stored upgrade order starts with tamper; fix grinder, basket, dose, or maintenance issues before adding optional tools.
