# DeLonghi Dedica Accessories | 51mm Tampers & Upgrade Kit ## DeLonghi Dedica Accessories — Transform Your EC680 / EC685 with Precision Puck Prep The **DeLonghi Dedica** (EC680 / EC685) is one of the most popular entry-level espresso machines, but it ships with accessories that limit its potential. The rubber tamper that comes in the box is designed for the pressurized baskets — swap it for a **precision 51mm tamper** and an unpressurized basket, and your Dedica becomes a genuine specialty espresso maker. ### The Dedica Upgrade Path The most impactful upgrades for the DeLonghi Dedica, in order of ROI: 1. **Unpressurized basket** — The stock pressurized basket hides extraction flaws. An IMS or VST-style unpressurized basket lets you taste what your grind and puck prep actually produce. 2. **51mm precision tamper** — The Dedica's 51mm portafilter is smaller than most machines. A calibrated flat tamper at 51mm ensures even pressure across the full puck surface. 3. **WDT tool** — Grounds from budget grinders clump. A WDT tool breaks the clumps before you level, preventing the dry cores that cause channeling in unpressurized baskets. 4. **Puck screen** — A 51mm or 58mm puck screen (depending on your basket) keeps the shower screen cleaner and creates a more uniform water contact pattern across the puck. ### 51mm — The Dedica's Unique Portafilter Size The DeLonghi Dedica uses a **51mm portafilter**, which is narrower than the industry-standard 58mm. This size is shared by a number of compact machines but requires purpose-fit accessories. Using a 58mm tamper on a 51mm basket causes severe channeling and can damage the basket. ### Compatibility Quick Reference Machine Portafilter Size Recommended Tamper DeLonghi Dedica EC680 51mm 51mm flat base DeLonghi Dedica Arte EC685 51mm 51mm flat base DeLonghi Dedica Style EC685M 51mm 51mm flat base DeLonghi La Specialista Arte EC9155M 51mm 51mm flat base ### Frequently Asked Questions #### What size tamper for the DeLonghi Dedica? The DeLonghi Dedica (EC680 and EC685) uses a **51mm portafilter**. The correct tamper is **51mm**. This is a distinctly smaller size than the 58mm found on most other home espresso machines. #### Do I need an unpressurized basket to use precision accessories? Not strictly, but yes in practice. Pressurized baskets are designed to tolerate inconsistent puck prep — swapping to an unpressurized basket is what makes precision tamping and WDT actually show up in your cup. Many Dedica owners do both upgrades together. #### Is the Dedica worth upgrading? Yes, within limits. The Dedica's pump and boiler are capable of producing specialty-quality espresso with the right accessories and a good grinder. The machine itself is not the limiting factor — the pressurized basket and plastic tamper are. Remove those limits and the Dedica's value proposition is excellent. #### What's the best upgrade order for the DeLonghi Dedica? Grinder first (if you're using a blade grinder), then unpressurized basket, then precision tamper. The WDT tool and puck screen are next-level refinements that reward you once the basics are dialed in. ## Products in this collection - [2-in-1 Espresso Tamper & WDT Tool Set, 51/54/58mm](https://theboringstore.xyz/products/espresso-tamper-set-wdt) -
