DeLonghi ECP3420 vs EC155 – What’s the same?

Type & Aesthetics

Both DeLonghi machines work with pumps that turn finely ground coffee into espresso in seconds. They help you save time by automating most of the pressurized coffee brewing process with an electric pump. Seems reasonable, the machine doesn’t look great, but it’s decent enough to put on the kitchen counter and drink coffee every day.


To help you generate high amounts of pressure and make espresso rather than regular coffee, both devices feature a 15 bar pressure. Given the cost of a coffee maker, the pressure is tremendous, because only expensive machines in cafes use such a device. If you don’t make dozens of coffees a day, the pump system is sure to last a very long time, and if properly cared for, even decades.

Pods or Grounds

One great feature of the DeLonghi ECP3420 and EC155 that makes all the difference in the morning is that you can use the coffee pods or beans to make coffee. Unfortunately, coffee makers don’t come with a built-in grinder because they are budget units rather than high-end devices, which benefits you by giving you an option to choose from a variety of coffee sources.

Easy-To-Use & Clean

Any of the DeLonghi coffee machines above is easy to understand, so even first-time buyers can figure out how to make their first batch of coffee at home fairly quickly. In addition, the cleaning process is very smooth with the removable drip pan and water tank to give you plenty of room to properly clean the device from time to time.

Temperature Control

When comparing the DeLonghi ECP3420 vs EC155, we found that both devices use the same temperature control system to control the water temperature for your coffee. You can choose from three temperature options to make your coffee faster or better tasting depending on the time situation.


For avid coffee drinkers, both devices have built-in froth, making them ideal for making lattes while adding milk to your coffee. The foam system is of decent quality and will help you get foamy milk quickly to make speciality drinks like lattes at home without any special equipment.

DeLonghi ECP3420 Vs EC155 – What’s so different?

Build Quality

Build quality is the first thing that sets the DeLonghi ECP3420 coffee machine apart from the EC155. The first device is more modern with better materials to make the device more durable, whereas the EC155 came out 15 years ago and there have been very few upgrades to the device.


The DeLonghi ECP3420 has a capacity of 37 ounces while other espresso machines lag by 35 ounces in water tank capacity. The difference may not be significant, but once you’ve made your first batch of coffee, you’re sure to get more cups from the DeLonghi ECP3420 coffee maker.

Heating Element

Although, both devices have boiler-based heaters that heat water in under a minute, making your coffee as fast as possible. The difference lies in the heating time as the DeLonghi ECP3420 takes less time to boil water in less than 45 seconds to win against the other devices.


The power consumption on DeLonghi ECP3420 vs EC155 is pretty much the same as the first device consumes 1100 watts, and the second device remains slightly lower with an average of 1050 watts. That makes the DeLonghi EC155 more energy efficient when you look at the long term use of both coffee machines.
