Delonghi ECP3420 vs ECP3120 – Taste
Ask yourself – what is the most important function of an espresso maker?
To create rich, creamy, and flavorful espresso that you can drink with hot water or steamed milk.
I don’t know about you but I have never liked the idea of combining instant coffee with frothed milk. The consistency and texture of the coffee is never right.
But with espresso, it just fits, you know?

The Delonghi ECP3420 is a wholesome and user-friendly pick. I didn’t have to tweak anything for it to deliver delicious espresso cup after cup. It works so fast producing great-tasting coffee consistently with a thick crema on top. The self-priming feature on start-up surely makes things easier.
For the best results go for medium-coarse ground coffee. The self-pressurizing espresso maker does a great job of extracting a smooth and full-bodied espresso each time.
The Delonghi ECP3120 requires you to prep more before but that isn’t so bad once you know what you’re doing. The one thing that really stands out is the tamping. I need to tamp just enough so that it isn’t too hard nor is it too light. So the espresso doesn’t come out too watery or burnt.
Like I said, I control the quality of espresso by making micro-adjustments with how I use the machine.
Delonghi ECP3420 vs ECP3120 – Performance

The Delonghi espresso maker allows you to adjust the time and pressure while brewing espresso. To get more control out of your compact machine, consider investing in a grinder. There is a dial that controls the step-by-step process of the whole brewing experience.
Dial it in and wait for the machine to heat up – there’s a green light that indicates the machine is ready to brew. The machine dispenses hot water that you can use to rinse and heat up the portafilter/cup.
This is where it gets interesting because in the ECP3420, the double-shot size is 13.5 grams which is good and ideal. In the ECP3120, the double shot filter basket is slightly smaller.
The rest of the performance, which includes dialing in again once the espresso is done extracting to steam the milk. Once the indicator light turns on after 30 seconds, the wand is effective and user-friendly to use.
That’s the extent of both espresso maker’s adjustable controls. You can brew two shots side-by-side. The machines feature a 3-in-1 filter holder for single, double, and coffee pods. And the steam wand is strong enough to heat up and texturize non-dairy milk as well as dairy milk.
Delonghi ECP3420 vs ECP3120 – Steaming Milk
The best thing about using a steam wand is that you can use it for any type of milk. Coconut milk, soy milk, almond milk, and oat milk.
The ECP3420 does an outstanding job of frothing milk for lattes and cappuccinos. On its own, it’s effective and useful for steaming milk daily. But when you compare, it does not match the precision and latte art quality texture of the ECP3120.
On the flip side, the ECP3120 takes a bit longer to froth milk. This is not a drawback but it is relatively slower than the ECP3420 to brew espresso and steam milk.
I simply have to turn the dial knob to the steam option, wait for 30-45 seconds, and place the milk jug underneath the steam wand. For best results, I recommend tilting the jug a bit to get a balanced and well-textured cup of latte or cappuccino. It sits well with the crema and espresso that the machine makes.
