Construction and Design 

The DeLonghi ECP3420 is best known for being budget-friendly; however, the company did not compromise on this coffee machine’s construction. 

The ECP3420 has a body made of durable ABS plastic coupled with stainless steel accents to produce a classic look. 

As such, it is easy to match this coffee machine with any kitchen décor. 

Moreover, these materials also make the ECP3420 lightweight and easy to move around. 

The DeLonghi ECP3420 also features a user-friendly interface. 

You can choose among four options (on, off, brew, steam) via a large dial found in front. 

Below, you can see the portafilter, which splits into two so that you can make up to two shots simultaneously. 

The ECP3420 also has a removable drip tray to accommodate larger cups or travel mugs. 

A 37-ounce removable water tank sits at the back, and this coffee machine also has a large storage compartment. 

Lastly, the DeLonghi ECP3420 features a 15-bar pressure pump and a built-in milk frother for milk-based drinks. 

Brewing Time and Capacity 

The DeLonghi ECP3420 is more suited for individual use as it has a brewing capacity of about four and a half cups. 

The 15-bar pressure pump enables the coffee machine to fully extract the flavors from the grounds to make authentic Italian espresso with its distinct rich, tasty crema. 

You can always adjust the pressure to your preferences. 

The ECP3420 has a self-priming setting that results in quick startup time, so you can immediately start brewing. 

The coffee machine’s rapid cappuccino system enables back-to-back serving as the system replicates the chosen drink and retains the optimal temperature in such a short time. 

DeLonghi’s ECP3420 also features a 3-in-1 holder that enables the user to define how many shots go in a cup. 

Built-in steam wand 

The DeLonghi ECP3420 comes with a built-in frother so that you can make milk-based beverages and desserts. 

The milk frother may not be the best since it can only steam small quantities of milk and produces inconsistent texture. 

However, it is sufficient for simple drinks and limited servings. 

Easy to clean 

DeLonghi has also made sure that their products were easy to clean, and the ECP3420 is no different. 

For one, this coffee machine has a removable drip tray, portafilter, and water tank that are dishwasher safe. 

With the ECP3420’s exterior, you can simply wipe it down for daily cleaning. 

DeLonghi also recommends descaling the ECP3420 at least for every 200 coffees. 

You can use the DeLonghi descaling solution, but you can also opt to use other brands or a 50-50 mixture of distilled vinegar and water. 

While the ECP3420 may be easy to clean, many users have reported that the machine gets easily dirty. 

Accommodates various cup sizes 

The DeLonghi ECP3420 can easily accommodate a cup size of 3.25 inches. 

However, you can easily remove the drip tray for travel mugs or larger coffee cups. 

As such, the ECP3420 can accommodate a cup size of 4.5 to 5 inches. 


Who is it for? 

The DeLonghi ECP3420 is a semi-automatic coffee machine that comes with various impressive features. 

Despite that, this coffee machine is still user-friendly and is a good option for beginners or those running a small café or restaurant. 

The ECP3420 is also ideal to use in business or corporate settings since it brews fast. 

Potential Drawbacks 

A potential drawback to the ECP3420 is that while it comes with a built-in frother, it does not make the best milk foam. 

The milk foam it produces can be underwhelming and sometimes inconsistent in terms of taste and texture. 

Another potential drawback is its limited use. 

The DeLonghi ECP3420 is best for individual use and thus, cannot keep up with the demands of group coffee orders. 


With its features, the DeLonghi ECP3420 is a simple entry-level coffee machine and is ideal for beginners. 

There are preset settings, but it still allows enough legroom for you to tweak the settings to their liking. 

Moreover, the ECP3420 is ideal for serving individuals or small groups due to having a smaller capacity. 

This coffee machine also has a fast startup and brewing time due to its self-priming and rapid cappuccino, making it ideal for those who rush in the mornings. 

Plus, the ECP3420 is also compact and lightweight that you can easily fit into your kitchen space.
