51mm

Tamper:

Portafilter:
pressurized
Stock:
51mm pressurized dual-wall baskets (single-shot and double-shot) held by a retention clip; forgiving of grind but not a precision-basket platform. We could not confirm the exact basket construction from a manufacturer spec sheet, so treat this as a spec inference rather than a documented figure.
First upgrades:
Tamper -> Dosing funnel -> Protective mat
Avoid:
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.

Before you buy

Common wrong buys: Assuming any '51mm' bottomless or spouted portafilter will fit — the group ears look proprietary, so a same-diameter part can still fail to lock in. · Chasing espresso-shop grind fineness with the pressurized baskets; grinding too fine chokes the machine, and the dual-wall basket won't reward it anyway. · Leaving milk in the 500 ml frother reservoir or skipping a rinse of the frothing path after use, which lets milk residue dry inside and clog the built-in frother. · Skipping regular descaling despite the 'internal cleaning function' — that cycle is not a substitute for periodic descaling of a 15-bar boiler, especially on hard water; follow the interval in your manual. · Overfilling the double basket or tamping unevenly, then blaming the machine when the puck sprays — technique, not hardware, drives most bad shots here.

Chefman CafeMaster Pro questions

What size accessories fit the Chefman CafeMaster Pro?

The Chefman CafeMaster Pro uses a nominal 51mm system. Confirm model-specific locking geometry before buying a portafilter body because diameter alone does not prove fit.

What should I check before changing the Chefman CafeMaster Pro basket?

This is a 51mm portafilter, the smallest of the common consumer diameters, so your basket options are far narrower than the 54mm and 58mm worlds. Buy 51mm baskets only.

Does the Chefman CafeMaster Pro need a separate grinder?

It has no built-in grinder. For non-pressurized baskets, use an espresso-capable burr grinder with adjustments fine enough to control the shot; puck-prep accessories cannot replace that control.
