What Is the ECM Synchronika II Espresso Machine
The Synchronika II is ECM’s flagship dual boiler espresso machine, manufactured in Germany with a steel frame and stainless steel housing. It is the second generation of the Synchronika line, adding cartridge heaters to the E61 group for faster warm-up while retaining the thermal stability that makes E61 machines prized by enthusiasts.
As one of the best prosumer espresso machines for cappuccinos and lattes in 2026, it has earned recognition for combining traditional E61 character with modern convenience. The 0.75L brew boiler and 2L steam boiler operate independently via PID control. The OLED display with rotary navigation manages temperature, pre-infusion, shot timing, and maintenance alerts.
The flow control valve — an OEM add-on from ECM, not stock on all units — allows manual pressure profiling during extraction. This is a key differentiator from the Lelit Bianca, which includes flow control as standard equipment.
The rotary pump runs at approximately 55–60 dB — quieter than vibration pump alternatives. This E61 espresso machine supports both the 2.8L removable reservoir and direct water line plumbing for permanent installation.
This E61 espresso machine runs on a rotary pump at approximately 55–60 dB during extraction, significantly quieter than vibration pump alternatives. It supports both the 2.8L removable reservoir and direct water line plumbing.
Key Features
6.5-Minute Fast Heat-Up
Cartridge heaters embedded in the E61 group head eliminate the traditional 20–40 minute warm-up. Turn it on, grind, and pull a shot. This makes daily use practical for busy mornings without sacrificing E61 thermal stability.
Dual Boiler System
0.75L vertical insulated brew boiler with internal heater. 2L vertical insulated steam boiler with auto-fill and internal heater. Brew and steam simultaneously with no temperature compromise.
OLED PID Display
Rotary navigation knob controls brew temperature, steam temperature, pre-infusion duration, shot timer, auto on/off scheduling, eco mode, and cleaning reminders. Intuitive enough for beginners, deep enough for enthusiasts.
Flow Control Valve
Adjust water flow rate during extraction for pressure profiling. Slow the flow for deeper body and sweetness. Increase for brighter, more acidic notes. Requires practice but unlocks flavor customization unavailable in standard machines.
2-Bar Steam Pressure
Commercial-grade steam output from the 2L boiler. Creates silky microfoam in 15–20 seconds. The no-burn steam wand with joystick control stays cool to the touch while delivering power.
Rotary Pump
Quiet, consistent pressure delivery at 55–60 dB. Supports both reservoir and plumb-in operation without vibration pump noise.
58mm Commercial Portafilter
Chrome-plated brass with bakelite handles. Includes angled single-spouted and double-spouted portafilters. Full-size baskets and tampers fit without adapter.
2.8L Water Reservoir
BPA-free, removable, top-access. 45 fl-oz stainless steel drip tray. Both support plumb-in conversion for permanent installation.

How Flow Control and Pressure Profiling Work
The ECM Synchronika 2 uses an ECM Flow Profile Valve for manual extraction control. This sits between the pump and the E61 group head, allowing real-time adjustment of water flow rate during the shot.
Why Pressure Profiling Matters
Standard espresso machines deliver full pump pressure from start to finish. This works for medium roasts but can extract too aggressively from light roasts or too passively from dark roasts. Manual extraction control lets you shape the pressure curve to match the bean.
For Light Roasts: Start with full flow for 5 seconds to saturate the puck, then reduce to 4–5 mL/sec for the remainder. This extends pre-infusion, enhances sweetness, and tames acidity that can taste sharp under constant pressure.
For Dark Roasts: Maintain full flow throughout. Faster extraction prevents over-extraction of bitter compounds that emerge when water lingers too long in a dense, oily puck.
For Flavor Profiling Espresso: Experiment with “blooming” — low flow for 15 seconds, a brief pause, then full pressure. This mimics high-end manual lever profiles and can reveal notes hidden by standard extraction.
The learning curve is steep. Expect 10–20 shots to find your preferences. The payoff is flavor customization unavailable in standard dual boiler espresso machines or E61 espresso machines without this capability.

This is the first upgrade from my Breville. I wanted a high end machine that I can work on. It was easy to set up and I am still learning the proper grind size for the machine with different coffee’s. The taste is way better and less bitter. I use medium and light roast coffee and it brings out the flavors I want. The quality of the ECM is more than I expected and it looks great. I will have this for many years to come. I have to mention the customer service. When I first ordered the ECM I paid for a special order before it was available on the site. When the site finally started to sell them they were at a lower price. I emailed them and they matched their own price. Great customer service!

I’ve had my ECM Synchronika with Flow Control for about a month and a half, and I’m having an absolute blast every single morning! I got the chrome version with black Bakelite handles and knobs. It’s gorgeous, and I don’t regret not getting the wood accents which might weather as wood tends to do. This machine replaces a 13-year old Alex Duetto II dual boiler that served me very, very well for 13 years straight. The Synchronika is a definite upgrade in terms of fit, finish, and the quality of my shots–not exactly sure why–but my shots taste noticeably better than they ever did with the Duetto, even without Flow Control. The Flow Control gauge and valve takes the fun and shot quality to a whole another level. Whether it’s pre-infusing and then ramping up the pressure or ramping up and then dropping the pressure to mimic a lever machine, it’s all fun, and the resulting espresso is outstanding. I’m sticking with the two-hole steam tip, as it generates near perfect micro-foam for me as quickly as I’m capable of making it (does a much better job of steaming for me than the Duetto ever did). I love the joy stick valves, and any fear I had that there’d be too much “all or nothing” pressure disappeared the first time I steamed milk. I am a huge fan of E-61 machines, because they are such a joy to use, even if a more expensive “push button” fool proof commercial machine could deliver more consistent shots. I used my purchasing credit to get the bottomless portafilter, and glad I did, but the standard curved double spout portafilter is also awesome, as it lays perfectly flat on the pad for tamping (and declumping with portafilter funnel and tool). I was a bit concerned about the “auto-off” “Eco Mode” feature that puts the machine “semi” to sleep after it’s been on awhile, but I actually like it. If I wait too long before making coffee and it goes into Eco Mode, I just quickly pull the lever, and the machine heats back up within a couple minutes. Also, if I forget to turn the machine off, no big deal, it just goes into Eco Mode. As I live in a super soft water area out West, I just keep a filled Brita filter on the side (sunshine takes all the chlorine out in a few hours), and use the pour over tank which is super, super convenient and easy since it drains from the bottom, and the lid just flips up on hinges–filling the Duetto was a chore as I had to use a funnel, and had to remove the entire top cup warmer tray. I know the Synchronika costs a few hundred more than most other dual boiler E-61 machines, but I have absolutely no regrets whatsoever, and I truly believe this machine will still be gorgeous and cranking out exceptional espresso for 15-20 years with minimal maintenance. As far as espresso machine depot goes, these folks are class acts from start to finish. I have nothing but accolades for everyone associated with this company.

I decided to wait a month or so to write a review for this machine. We’ve had our Synchronika up and running for a few weeks and are very pleased with the results. I’ve been an espresso lover since my first demitasse at the Allegro in the 1970’s. Over the years I’ve had various home machines, most recently a trusty Miss Silvia/Rocky combo which served well for over a decade. I’ll say my shots on the Silvia were quite good, but wow, the Synchronika ii takes it to a new level. Precision. Ease of Use. Consistency. All amazing. Honestly, I’d have trouble finding better coffee at a local espresso shop – and I live in the Northwest. When I first got the machine going I was so thrilled with the results I was drinking like five doubles a day. So good. Installation details. Atom 65 grinder. We plumbed water but not drain. Using a water filter. Decided not to regulate pressure. Wired machine on a separate 15A breaker. Added Alexa-controlled plug so Synchronika ii is warm and ready when we wake up in the morning. The * is related to build quality. When the machine arrived I noticed the drain tray didn’t sit flat – it was warped and rattled loudly when I pulled shots. I conferred with the good folks at EMD and they suggested I just muscle the tray flat, which, after some trial and error, I was able to do. The machine still has a few other rattles, but I’m slowly eliminating them with small bends, gentle taps, and bits of (Italian) handlebar tape.

I’ve been using a La Spaziali Vivaldi S1 for 16 years. It’s a good solid machine that served me well. It was time for an upgrade and I had my eye on a La Marzoco Linea Mini. La Marzoco raised the price right out of my range. Jessica was very helpful. She showed me the ECM Syncronika ii and suggested it could pull an equivalently great shot and it was still within my price range. After gathering info I took the plunge. This is an excellent machine and after dialing everything in, I’ve pulled some amazing shots. It is also a steam monster. Very happy with this machine.

I recently upgraded to this machine after owning a Quick Mill Andreja (also a great HX machine). I wanted to go to a dual boiler with rotary pump, with future plans to direct plumb, and also wanted a machine where repairs were as simple as possible at home (should there ever be a need). There are a lot of great choices with dual boilers/rotary pump, however the internal design is really what sold me on the ECM. Very well laid out internals, and the overall build quality of the machine exceeded my expectations. The PID controller is awesome, and gives me an extra measure of control. The angled portafilters and joystick steam/hot water wands, along with the pressure gauges up higher on the machine (and in better sight lines) make it worthy of the additional cost vs its Pro 700 brethren. So far I am more than happy with my purchase, and the Support staff have been nothing short of amazing.

Coming from a Breville Oracle touch, there is a learning curve to this top of the line machine but once you make it around that hairpin, this machine is a breeze to pull shots from.
The National Espresso Machine Finals was between this bad boy and the LMLM, watching a ton of videos on YT and Reddit 2cent-ers. I ended up swaying German with NO regrats, not even a single letter.
Set up was a breeze, read the manual so you get a gist of how to navigate the menus. Warm up times were faster than the Breville which is amazing considering a 54 vs. E61 group head.
Pump pressure is great, frothing is a breeze once you get hang of it (nothing negative against the machine more of learning curve of the user).
Fit and finish- it’s a beautiful machine, I opted for the non wood version. Knobs feel nice and well balanced.

I upgraded from a Delonghi Dedica, which I used happily for 7 years (still working). I had reached the upper limit of what I could do in this hobby with that machine and have really enjoyed being able to adjust many new variables when making my espressos. Being able to adjust brew temp is great, the flow control (which I wasn’t too sure I would like) was a pleasantly powerful tool. The quick heat up time made this machine stand out compared to comparable machines such as the Bianca V3. This machine is beautiful and although I will never financially recover, I have something to look forward to each and every day.

I’ve had my Synchronika ii for a few days now and it has been great. It arrived in perfect condition (no shipping damages). I had to change my shipping address after I placed my order and customer service got it updated quick and easy. After using more of an entry level machine for the past 6 years I couldn’t be happier with making the decision to go ‘prosumer.’ I was blown away at the difference between the two machines and how much control the ECM machine gave me. I also couldn’t believe I still had a learning curve after years of espresso making! Having the naked portafilter Read more about review stating Stepping up to the big leagues!was also a game changer so I could see what was happening with my shots as I dialed in the machine. You will be surprised how different shots can taste with very subtle adjustments on in inputs. I have a favorite pizza place in Seattle that has a hand pull espresso machine; (shout out to Tutta Bella on Stone Way) for years I haven’t not be able to match their espresso until I dialed in the Synchronika and now I can top it! The ability to pull a few shots in a row and have enough steam to make a few lattes is also sooooo much nicer than my old single boiler machine. I haven’t come close to running out of boiler or steam power after making a few in a row! Of course, it also looks fantastic on my coffee bar as well and everyone who comes over notices it.

Love my new ECM. It replaced a 20yr+ old ECM. The double boilers and quiet pump are clear upgrades. I hope this one lasts as long. The PID took a bit of time to learn how to adjust. The instruction book can be done with better instructions.
Todd C. –
Arrived well packaged and on time. My new ECM espresso machine is absolutely perfect.
Kenny H. –
Pulled my first shot, perfect! I think this Expresso machine should last much longer than my old one.

Finally pulled the trigger after years of drooling over prosumer machines and let me tell you, this thing does not disappoint. I am 55 and have been messing around with espresso for years so I know a good machine when I use one. This thing warms up crazy fast and the steam pressure is excellent. The interface is super intuitive too, like everything just makes sense right away. Yeah it is a big machine but honestly who cares, it looks gorgeous on my counter. I snagged it during the black friday sale and they threw in a bunch of goodies, which was a sweet bonus. Super pleased with the whole thing overall. I am running on the reservoir for now but I am definitely planning to get it plumbed in soon.
