ECM · Dual boilerSynchronika II
ECM's flagship E61 dual-boiler refined with cartridge-heated brew group, OLED PID dial control, and active/passive pre-infusion — the fastest-heating E61 on the market and a legitimate long-term machine.
The short version
The Synchronika II takes ECM's proven dual-boiler platform and solves the one thing that always annoyed E61 owners: the 35-minute wait.
What you accept in return is a large, heavy footprint, no volumetric dosing, and a flow-control device that costs extra.
Why people buy it
- Fastest-heating E61 dual-boiler on the market — brew-group cartridge heaters enable ~6.5-minute fast start, measured independently at 8 minutes to full thermal saturation
- 2-bar steam pressure with joystick valves produces dry, dense microfoam fast enough for a dinner-party milk run
Why they don’t
- No volumetric dosing — every shot is manual-timed, which adds a learning curve and variable weight if you change beans regularly
The full tally
- Fastest-heating E61 dual-boiler on the market — brew-group cartridge heaters enable ~6.5-minute fast start, measured independently at 8 minutes to full thermal saturation
- 2-bar steam pressure with joystick valves produces dry, dense microfoam fast enough for a dinner-party milk run
- OLED + rotary dial brings active/passive pre-infusion, dual-boiler PID, auto on/off scheduler, and shot counter into one legible, tactile interface without opening the machine
- German-manufactured stainless steel chassis with commercial-grade internals — the kind of build that outlasts the owner's interest in espresso
- No volumetric dosing — every shot is manual-timed, which adds a learning curve and variable weight if you change beans regularly
- Flow control requires a separately purchased ECM Flow Profile Valve; it is not included at the standard price
- At 30 kg and 490 mm deep, this machine dominates a counter and is non-trivial to move for cleaning or maintenance

Worth knowing before you buy — Most owners say: this is where the grinder budget conversation ends — invest here in the machine, invest harder in the grinder.
“The ECM Synchronika has everything a good espresso machine needs. It boasts high temperature stability during brewing, is well-made...”
“Everything you've read about the build quality of this machine is IMHO spot on.”
“I've had a Synchronika for over 2 years and absolutely love it. No problems and very consistent. Quiet rotary pump. Easy to maintain.”

Living with it
The part spec sheets skip: counter space, upkeep, and what owners learn later.
The honest note — Most owners do not outgrow this machine — it is already near the top of the traditional home-prosumer class. The natural next step is adding the ECM Flow Profile Valve for pressure profiling, or moving to a software-first profiling machine (Decent DE1) if logged multi-step profiles become the priority. Lateral moves toward the La Marzocco Linea Micra trade saturated-group speed for a smaller footprint.

Before it arrives
What completes this machine — the faded pieces can wait.
Water filter / softener — Plumbed-in machines need inline filtration to keep scale out of the boiler — it is cheaper than a repair.
- Water filter / softener — Plumbed-in machines need inline filtration to keep scale out of the boiler — it is cheaper than a repair.
- Descaler & backflush kit — Electric boilers scale up and grouts gunk up — a descaler plus backflush routine is what keeps the machine alive for a decade.
- Coffee scale with timer — Espresso is a ratio. A 0.1g scale with a built-in timer is the single biggest consistency upgrade for any manual machine.
- Knock box — Somewhere to bang the spent puck that is not your kitchen bin.
- Calibrated tamper — The bundled tamper is usually an afterthought; a fitted, calibrated one makes prep repeatable.
- WDT distribution tool — Breaks up clumps before tamping — a cheap fix for channeling on any portafilter machine.
- Espresso cups & glassware — Proper demitasse and latte glasses keep the drink hot and look the part.
Feed it right
Week one is dial-in — and stale beans will lose it.
Coffee more than a few weeks past roast won’t extract predictably, and a new machine gets blamed for it. A machine in this class will show you the difference between roast dates — it deserves beans that change week to week.

Common questions
How long does the ECM Synchronika II really take to heat up?
ECM markets a 6.5-minute brew-group fast start enabled by two 200 W cartridge heaters built into the E61 group. Independent testing by Kaffeemacher measured 8 minutes to brewing readiness — the steam boiler needs a few additional minutes beyond that for full steaming pressure. Either figure is record-fast for an E61 machine.
Does the Synchronika II come with flow control?
No. Flow control is available via a separately purchased ECM Flow Profile Valve that mounts on the E61 group. The machine is compatible with it, but it is not included at the standard price.
Can the Synchronika II be plumbed directly to a water line?
Yes. The machine switches between a 2.8 L internal water tank and a direct water line connection. The rotary pump supports both modes, and plumb-in also enables line-pressure passive pre-infusion.
What grinder should I pair with the Synchronika II?
A midrange stepless espresso grinder is the minimum — think Niche Zero or Eureka Mignon Specialita. The machine's thermal stability and rotary pump will expose grinder inconsistency quickly, so a premium flat-burr single-dose grinder is the natural ceiling pairing.
Is the Synchronika II a semi-automatic machine?
Yes — it is a semi-automatic with no volumetric dosing. You start and stop the shot manually (or by time). This is part of the intended hands-on workflow, not an oversight, but buyers who want timed volumetric control should note the absence.
