ECM Synchronika II Espresso Machine

The Synchronika II is built for experienced home baristas who want endgame-level equipment without stepping into commercial territory. Its dual-boiler design, rotary pump, and switchable water supply (reservoir or direct plumb) make it ideal for households pulling multiple drinks back-to-back—think entertaining or multi-person mornings. What distinguishes it is the refinement: an intuitive OLED PID interface, active and passive pre-infusion, and a 6.5-minute fast heat-up mode that's first in class among E61 machines.

The Synchronika II's OLED PID lets you toggle between two pre-infusion approaches. Passive pre-infusion uses line pressure from the water supply to gently saturate the puck before the rotary pump engages, producing a softer, more even extraction.

Active pre-infusion engages the pump at a controlled, lower flow rate before ramping to full pressure. Both are adjustable through the PID interface. Add the optional LUCCA Flow Control device, and you gain full manual profiling over the entire shot, giving you café-level control at home.

Clive's preventive approach starts with testing your water using Water Hardness Test Strips to establish a baseline. Clive recommends a water hardness of 35–85 ppm. Use a BWT Water Softening Pouch, Oscar Water Softening Pouch, or a Home Water Softening and Filtration System to keep minerals in the ideal range. Consistent water management is the single most important step to protecting your investment in

The Synchronika II is a substantial, heavy-duty machine. Plan for roughly 19 inches of depth. You'll also want clearance above for filling the reservoir and behind for ventilation, especially if plumbed in. Pair it with a quality grinder. Clive's team frequently pairs it with the Mazzer Philos. Confirm your counter can handle the combined footprint. Clive's baristas can walk you through placement and setup over the phone.

The Synchronika II sits near the top of Clive's prosumer lineup. Most buyers upgrade from capable single-boiler machines like the ECM Classika PID with Quick Steam or heat-exchangers like the Mechanika Slim PID, seeking true dual-boiler temperature stability and simultaneous brewing and steaming. It's also a natural step up for anyone outgrowing entry-level dual boilers. For those wanting even more, Clive recommends a machine like the La Marzocco Linea Mini, but for pure E61 dual-boiler performance, the Synchronika II is the pinnacle.
