Diletta Bello+ Espresso Machine Review — PID Temperature Control, E61 Review
What if you could bring café-quality espresso home without the commercial price tag? The Diletta Bello+ is a heat exchanger (HX) espresso machine designed for the home barista who values consistency and craftsmanship. Handmade in Milan, it combines traditional E61 group head engineering with modern PID temperature control, an integrated shot timer, and programmable preinfusion. This machine targets those who have outgrown entry-level models and want greater control over every variable—boiler temperature, preinfusion time, and shot timing. The Bello+ also adds a low-power eco mode for energy savings, a nod to daily usability. With a 3-liter boiler and stainless steel construction, it promises durability and the ability to brew and steam simultaneously. But is it the right upgrade for your kitchen? This review digs into its build, performance, and real-world user experiences to help you decide.
Product Overview
The Diletta Bello+ is a semi-automatic heat exchanger espresso machine that uses a large 3-liter steam boiler to also heat brew water on the fly. This design allows simultaneous brewing and steaming, a key feature for milk-based drink enthusiasts. The stainless steel case, frame, and boiler contribute to its tank-like build quality, while the E61 group head—a standard among prosumer machines—ensures thermal stability and parts availability. Dimensions are 17.75" deep, 11" wide, and 14.5" high, making it a substantial countertop presence. The machine comes with a 58mm portafilter, tamper, single and double baskets, and a cleaning brush. Power consumption is 1500 watts at 120 volts. The front-mounted PID screen displays boiler temperature and doubles as a shot timer during extraction. Programmable preinfusion up to 10 seconds allows for gentle wetting of the coffee puck before full pressure, improving uniformity. The low-power eco mode reduces boiler temperature when idle, saving energy while maintaining faster recovery compared to full shutdown. Water capacity is 3 liters, and the drip tray has been deepened for better capacity. Manual controls—a brew lever and steam knob—keep the barista in full command. Input coffee type is ground, and the filter is reusable. The Bello+ is not smart home compatible, keeping the experience traditional. Users report that the factory smell requires a thorough initial flush, but it dissipates. The included portafilter is a standard E61 type, allowing easy upgrades to bottomless or custom options. Overall, the Bello+ blends Italian craftsmanship with useful modern features for the discerning home barista.

Build & Materials
The Diletta Bello+ is built around a stainless steel chassis and a 3-liter steam boiler, both contributing to its substantial weight and thermal stability. The E61 group head, a hallmark of prosumer machines, is machined from brass and chrome-plated, providing excellent temperature retention and easy serviceability. The machine’s exterior is finished in either black or white powder-coated stainless steel, with chrome accents on the steam wand and group head. The PID controller is mounted on the front panel, flush with the fascia, and reads clearly during operation. The drip tray has been deepened by an inch over the original Bello, offering better capacity for backflushing and multiple shots. The steam wand is a cool-touch design, preventing accidental burns. All water connections use standard fittings, and the reservoir is accessible from the top without moving the machine. Internal wiring and plumbing are neatly routed, reflecting the hand-assembled Italian craftsmanship. Users mention that the machine feels solid and well-weighted, with no rattles or loose components even after months of daily use.
Shot Quality
The Bello+ delivers a classic E61 brewing profile with the added precision of PID control. Because it is a heat exchanger machine, brew temperature is influenced by the steam boiler's set point and the cooling flush technique. The PID allows users to dial in the boiler temperature with greater accuracy than traditional pressurestats, though some flushing is still required to stabilize the group head temperature. Many reviewers report that after a 30-50 minute warm-up and a brief cooling flush, the machine produces consistent, balanced shots with good body and clarity. The programmable preinfusion helps reduce channeling when using lighter roasts or finer grinds. Steam power is ample: the 3-liter boiler provides strong, dry steam that microfoams milk quickly—users praise its ability to texture milk for latte art. Simultaneous brewing and steaming is possible without significant temperature drop, a key advantage of the HX design. However, the machine’s performance depends heavily on grinder quality and puck preparation; several reviewers noted that upgrading from an entry-level machine required refining their technique to avoid channeling with a bottomless portafilter. Overall, shot quality is rated highly by experienced users, though beginners may find the learning curve steep.
Pros and Cons

What Doesn't
- ✗Learning curve is steep for beginners; not novice-friendly.
- ✗Drip tray could be larger despite the depth increase.
- ✗Requires a quality grinder to realize full potential.
- ✗Initial factory smell needs thorough flushing to remove.
- ✗HX machines require a cooling flush technique for optimal brew temperature.

The Verdict
The Diletta Bello+ is a well‑crafted heat exchanger espresso machine that successfully marries traditional E61 design with modern PID convenience. Its build quality is exceptional, and the addition of a shot timer, programmable preinfusion, and eco mode adds genuine value for the daily user. Performance is excellent when paired with a capable grinder and proper technique, rewarding the operator with café‑quality shots and steam. However, the HX design requires a learning curve and a willingness to learn flushing routines, making it less ideal for absolute beginners. At $1,899, it sits in a competitive segment where dual‑boiler machines also exist, but for those who appreciate the E61 workflow and Italian craftsmanship, the Bello+ is a strong contender. It earns a high recommendation for intermediate to advanced home baristas who value consistency and are willing to invest time in mastering their craft.
