De’Longhi ECP3420 Review With Buying Guide 2021

Whom is this product for?

No matter you’re a homemaker, a corporate job-holder, or a coffee shop owner, a good quality coffee machine is a must. Here is a list of settings that the De’Longhi ECP3420 is suitable for:

  1. Residences that are home to coffee lovers.
  2. Restaurants or cafes.
  3. Businesses or corporate spaces.
  4. Community centers, gathering spaces, events, etc.

It is still worth noting that although the De’Longhi ECP3420 can be used in restaurants and cafes, it is technically not meant for this purpose. We would not recommend it for busy coffee shops.


Overall, the De’Longhi ECP3420 has a relatively sleek and contemporary build that allows it to easily fit into any type of kitchen or culinary space.

In terms of its technical specs and features, the De’Longhi ECP3420 is well-suited for preparing espressos, cappuccinos, and lattes, To facilitate this, it has a 15bar pressure input that can be adjusted based on your personal taste. No matter what beverage type or pressure you choose, you’ll always get a cup of barista-quality coffee in the end.

In addition to this, you can also define the number of shots that you want each time through its 3-in-1 holder.

Furthermore, in the case that you need to have multiple servings right away, the De’Longhi ECP3420 also has a rapid cappuccino system that is designed to serve you several cups in quick succession. On top of that, you can have the same facility for any size of a cup.

Another quality of life feature that makes the stand out from its competition is its self-priming setting that allows for a quick startup time so that you can start brewing sooner.

The De’Longhi ECP3420 is also notable for its ability to adapt to a wide range of cup sizes since it gives users the ability to adjust the height of its bottom tray. In addition to this, while its 37-ounce water tank may not be the largest, it is still capable of holding enough water for several cups of coffee before it needs to be refilled.

Furthermore, the design of the tank lets users see the water level at all times – a convenient feature that removes any guesswork from estimating when the water will be depleted.

What Is The Difference Between a De’Longhi ECP3420 and DeLonghi ESAM3300?

Although they are both De’Longhi models, the ECP3420 and ESAM3300 do still have notable differences that are worth mentioning. At first glance, the most prominent difference between these two machines is their prices. In virtually all marketplaces you will find that the De’Longhi ESAM3300 is pricier than the De’Longhi  ECP3420

Here are some of the other notable differences:

  • The Water Tank

The ESAM3300 has a 60oz reservoir with a bean container capacity of 8.8oz, while on the other hand, the ECP3420 has a 37 oz water tank. This largest capacity is one of the main reasons why the ESAM3300 is more expensive. 

  • The Beverage Types

The ECP3420 is a specialized espresso coffee maker and in addition to being able to create high-quality espressos, it can make great-tasting lattes and cappuccinos as well. However, the ESAM3300 is a bit more fleshed out in terms of the options it provides. In addition to being able to brew multi-strength espressos, it can also create cappuccinos, lattes, Americanos, and so on. Furthermore, the complexity of its flavors and its grinding capabilities are noticeably better than the ECP3420.

  • The Usability

When it comes to speed and usability, both models are fairly even – however, they do have different features that they use for brewing. The ECP3300 has a smart design and the entire brewing process is automated. In addition to this, it requires very little maintenance and you don’t need to descale or clean it on a regular basis. The only thing that you may need to look out for is water spills that are caused by blockages. 

On the other hand, the De’Longhi ECP3420 is not as automated as the ECP3300. It is still notable for having an automatic flow stop that lets you dispense precise amounts of espresso. For both models, the water tanks are easily removable, and the parts are completely dishwasher safe. 

Customer Feedback

‘After spending money on several cheap quality coffee makers, I decided that I needed a machine that could produce better quality brews. After an extensive amount of research, I had the ECP3420 on my shortlist and so I decided to give it a try. Although it’s less automated compared to many $500+ models, I’m happy with it so far, especially when I consider its low price and the high-quality coffee that it brews.’

‘The clearance between the dispenser and the base is pretty impressive. I was actually looking for one such model and I’m glad that I finally got it. Also, the single and double size variation is what I love the most about the De’Longhi ECP3420′

‘I have been using this machine since 2011. For middle-ranged users, I think this is a good one. I use it almost daily and drink roughly 10-15 cups from it every week. The steamer power is good, and the pump is still strong after these many years of use. My only minor complaint is the startup time which has recently become a bit slower.’

  1. I was giving the ECP3420 model as a Christmas present in 2019 to replace a small expresso maker, which was on its last legs. There is a learning process to adapt from the old expresso maker to the Delonghi model. Also, adjusted to the amount of milk to froth and amount of heat. Once I got the hang of monitoring the amount of coffee being poured into a mug and frothing the milk, I truly enjoyed over a year’s worth of tasty and frothy coffee. What I didn’t learn early on is the process to descale the expresso maker. I first encountered problems getting coffee to pour out due to a clogged filter, which the Delonghi FAQ suggested to clear the filter wholes. It was around 6 months before this happen. Second issue I encountered was water leaking from under the expresso machine. Again went to the FAQ and other sites, which pointed to the water tank plastic rings were not tight or needed to be replace. I got so tired of the water leaking under the machine that I had to pull the water tank out after each coffee cup. Finally, I realized that I needed to descale the machine, which I was able to successfully but it seem to make things worse. Steam started to seeping out from all parts of the machine, the steam pressure was uncontrollable and couldn’t get a good cup of coffee without dealing with the leaking and steaming. Delonghi should emphasis descaling of their expresso products. I’ve learned a lot about these expresso machine and look to purchase another Delonghi expresso maker and take better care of it.
