Gaskets 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 gaskets - 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 gaskets
Does any 51mm gasket 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 gasket 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.
