Delonghi Dedica EC680BK vs ECP3420: Differences
Narrow design

The Dedica EC680BK only takes up 6 inches of counter space with a 35 ounce water tank, a milk frother, and all stainless steel parts. The stainless steel details make the machine look compact yet sturdy. It is 15 centimeters wide and 33 centimeters deep. So its footprint is efficient and user-friendly.
Despite its small size, it even features a height-adjustable drip tray. It looks stylish, is well-designed, and it can perform just like a barista-grade espresso machine.
The Delonghi ECP3420 has a slightly larger water tank of 37 ounces. It looks like an entry-level espresso machine with a wide frame and mid-length height. In that way, the Dedica is taller and the ECP3420 is wider so it takes up more counter space.
Thermoblock Technology

Thermoblock technology is faster and more energy-efficient. It offers better temperature control than boiler systems both single and dual boilers. The Dedica is more advanced because of Thermoblock technology. So great that you can use the hot water dispenser to make oats, hot chocolate, and green tea.
The Delonghi ECP3420 uses a boiler system. It is reliable and efficient but it pales in comparison to the Thermoblock technology of the Dedica. But if you’re looking for a basic yet effective espresso machine with high-quality temperature controls, the ECP3420 is a budget-friendly pick.
Cup Warmer
A cup warmer goes a long way to ensure the freshness of coffee even after it brews. If you wake up to a busy schedule, having this extra feature is quite helpful. And especially in more compact kitchens, a useful feature is never unwelcome.
You can place one cup at a time to keep it warm. The stainless steel drip tray remains sturdy and solid. So you can just leave the cup on the drip and step away for a few minutes easily. It also comes in handy when you want to froth the milk at the side and keep the espresso nice and warm.
The Delonghi ECP3420 also includes a cup warmer. However, it’s not to be relied upon as it offers inconsistent heating especially with thick mugs.
Automatic Flow Stop
The Dedica will automatically deliver one or two shots of espresso as per your liking. The unique flow stop feature is a blessing if you’re little to no acquainted with how espresso machines work.
It brews the exact dose every time without any delay or inconsistency. And the flow is smooth, crema-infused, and fast. No extra dripping after the flow stops so you have less to worry about cleaning afterwards.
The Delonghi ECP3420 has a manual stop feature which means you have to manually stop the flow to avoid making the espresso too light and watery.
