Bottomless Portafilters for the De'Longhi Dedica Duo
- Size matches the 51mm De'Longhi Dedica Duo group.
- Listing names a DeLonghi model or machine it claims to fit.
- The EC890M has no built-in grinder - pre-ground or a separate grinder is required, and non-pressurized basket upgrades are only worthwhile with a capable espresso grinder.
- 51mm De'Longhi/SMEG accessories are widely cross-listed for the older Dedica models (EC680/EC685/EC885, SMEG, EUPA), and De'Longhi lists the EC890M with the same 51mm portafilter - but as of this writing most third-party listings still name only the older EC-codes, not the EC890M/Dedica Duo. We infer the EC890M shares the Dedica 51mm ear geometry from its portafilter size and product family; it is not yet confirmed on retailer listings, so check that a listing explicitly names a Dedica/EC890-family fit before buying, not just '51mm'.
- This is a thermoblock machine with no 3-way solenoid / true group, so espresso-machine backflush discs and blind-basket routines do not apply.
- What size to buy
- Buy 51mm for the De'Longhi Dedica Duo.
- What to avoid
- Avoid 54mm and 58mm bottomless portafilters - they will not fit the 51mm group.
- Upgrade priority
- Recommended early - a high-impact upgrade.
- If you own another machine
- Own a Breville Bambino? Use the 54mm page instead - these 51mm parts will not fit it.

Before buying bottomless portafilters
Does any 51mm bottomless portafilter fit the De'Longhi Dedica Duo?
No. The nominal size is only the first check. Model-specific locking geometry, basket depth, mounting pattern, or clearance may also matter. The EC890M has no built-in grinder - pre-ground or a separate grinder is required, and non-pressurized basket upgrades are only worthwhile with a capable espresso grinder.
Is a bottomless portafilter the first upgrade to buy?
Not automatically. The De'Longhi Dedica Duo's stored upgrade order starts with filter basket; fix grinder, basket, dose, or maintenance issues before adding optional tools.
Will a bottomless portafilter fix channeling?
No. It exposes the underside of the basket so uneven flow is easier to see; grind, distribution, dose, tamp, and basket condition still determine the result.
