Capresso EC100 Review 2026: Better at Milk

A thermoblock is an aluminum block with a heating element and a thin water channel. Water is heated as it flows through instead of waiting in a boiler, which is why these machines are ready within a minute and stay small and cheap. The EC100 adds a large front-fill tank and a pump that forces that heated water through coffee.

A pressurized basket adds a small restrictor at the exit, so pressure builds even when the grind is imperfect. That forgives uneven grounds and stale beans, but it also hides the feedback that teaches you to grind finer or coarser. For the cup, expect reliable crema and a rounder, less detailed shot than a standard basket gives.

The twin frother is an air-assist wand: a sleeve mixes steam and air into milk automatically. It gives you thick foam without technique, which suits cappuccinos, but it cannot make the glossy microfoam that latte art needs.

Thermoblock machines drift in temperature, especially after steaming. Run a blank shot through the empty portafilter to warm the metal, and let the ready light settle before brewing. Cooler water is the usual cause of sour espresso; a hotter, rushed shot is where bitter espresso starts.

Scale is the other slow killer. Use filtered or softened water and follow the descaling guide on schedule, because mineral build-up narrows the block's channel and cuts flow. Rinse the portafilter and group screen after each session, as covered in cleaning an espresso machine.

If milk foam turns flat, the frother sleeve is usually blocked with dried milk, so soak and rinse it daily. Weak flow after a few months is typically scale rather than a pump failure; see fixing a steam wand that will not froth for related checks.
