The Good The DeLonghi EC155 Pump Espresso is compact, affordable and makes very tasty espresso-based drinks paired with steamed milk.

The Bad Unfortunately the DeLonghi EC155 lacks the power and temperature control to pull consistently delicious espresso shots. The machine also has trouble extracting flavor from medium and lightly roasted beans.

The Bottom Line If all you seek in a home espresso machine is the odd cappuccino or latte, then the budget-minded DeLonghi EC155 Pump Espresso is tempting. However aficionados won't be impressed by its erratic coffee quality.

Making decent espresso-style drinks at home doesn't have to be exorbitantly expensive. For a modest $100 (£110 in the UK) the DeLongi EC155 Pump Espresso can whip up satisfying espresso, lattes, and cappuccinos, and without eating up too much countertop real estate.

Of course this small machine is no stand in for elite and more robust espresso makers. Saddled with a weak vibratory pump, a single boiler and erratic water temperature control, the EC155 is tricky to operate with consistent results. It also gets bogged down by ultrafine grinds and has difficulty extracting all the subtle flavors locked within medium and lightly roasted coffee beans. That said, if your espresso tastes lean towards the more traditional dark roasts and have a penchant for adding a dollop of steamed milk then the DeLonghi EC155 Pump Espresso is a very affordable and tasty option.


Closer in size to small pod-style coffee makers, the DeLonghi EC155 measures 10.5 inches tall by 7 inches wide by 8.25 inches deep. It also tips the scales at a mere 7 pounds, 2 ounces making it a cinch to transport around the house or even out the door. Another convenient aspect of the appliance is its removable water tank. Holding 34 ounces (1 L) of liquid, the square-shaped reservoir is easy to pull out or drop into the espresso machine thanks to its built-in handle. And since the tank has a flat bottom you can rest it worry-free on tables and counters for quick fills.

As you'd expect from an espresso machine, the EC155 uses a portafilter device to both load, contain and brew its coffee grounds. Essentially a metal handle (with rubbery grip) on one end with a circular basket and filter attached to the other, the portafilter is built to withstand the high pressures and temperatures of espresso brewing. When properly mounted, the portafilter screws tightly into place within the grouphead at the center of the machine.

DeLonghi thoughtfully includes two metal filters with the EC155, one to handle single shots and another for creating double shot coffees. Both filters share the same circumference and drop neatly inside the portafilter basket. The major difference between the two are their depth and recommended ground coffee capacity. The shallow single shot filter accepts 7 grams (0.2 ounce) of coffee while the deeper dual shot filter tops out at 12 grams (0.4 ounces).

I found the EC155 Pump Espresso's few controls easy enough to use. On the front face of the machine is a big dial, what DeLonghi calls the "selector knob." The dial has four marked positions, and associated symbols, which kick the product into various operation modes. These include resting, heating, espresso brewing and steaming.

To the right of all these icons is a temperature indicator light which glows green when the EC155 thinks its water is hot enough for either brewing or creating steam, or red if not. You'll also find a thick steam controller knob on the machine's top side. Swiveling it clockwise or counterclockwise increases or decreases the flow of steam from the EC155's dedicated wand appendage.


If you're expecting the DeLonghi EC155 Pump Espresso to deliver the same quality of espresso as machines costing two, three or even five times as much, you're in for a dose of harsh reality.

Equipped with a small vibratory pump instead of the massive rotary pump mechanisms you'll find inside elite commercial and even domestic machines, the EC155 lacks the oomph to push hot water through very fine coffee grounds. In fact attempting to brew extra finely ground beans (processed by my Capresso Infinity Conical Burr Grinder) caused the Pump Espresso to clog completely.
