Brian and Marc, thanks for the great set of videos on the Synchronika! I have an ECM Barista (HX) with rotary pump and my pressure was running very high 14bar with blind basket. Attempts to adjust via bypass valve resulted in no change with screw position. It took a descale to free the adjustment valve and achieve 9 bar. Will be looking into filter options going forward to prevent the need for excess descaling.

Thanks, Marc & Brian. Your support for these machines is very much appreciated.

Thank you. I have been adjusting the pump pressure every year and this video has been very helpful.

This is really helpful. I had my brew head gauge at 8 for two years and recently it’s slipped to around 6 bar. Now with this easy adjustment I’m back to 8 bar at the brew head!

Thanks Brian for the quick response. Look forward to the Technika reviews!

Thanks for the video. For those of us who have never done it before, It would be nice to see your hands while you're adjusting that pump to know which way you were turning the adjuster screw (clockwise/counterclockwise) to increase/decrease the pressure.

Finally I got an answer for the brew pressure gauge on my Synchronika. I've been experiencing this climbing pressure up to around 12 bars with the blind filter basket since I've put the flow control kit.

Thankyou so much! Totally needed this video

Bought an ECM Synchronika with flow control here in Australia based on your videos and recommendations. Big thanks for all the detailed reviews and service videos like this one.

You guys are great

It's really cool here on Synchronika as you don't need to open the whole chasis.

Just for added info. Anticlockwise will lower, and clockwise will raise the pressure.

Damn so love it many thanks mate

Thanks for the review. Would really like to see a similar review on the ECM Technika Profi V.

Hello Guys. Thank you for that great video. I have a question. Is there a reason why the pressure is going up to around eleven bar by itself? It was around 9 all the time and now i realised it's much higher and when i brew a shot the lowest valve is letting water out... I wonder why that started suddenly...

Hi Brian! Is it normal to rely on the OPV, or would it be ideal to have most of the pressure limited by the puck? I ask because my OPV on my vibratory hx is constantly in use (pressure rapidly moving around OPV set point). Is that okay?

I used to have a M&V pressure profiling Vesuvius machine, one of the preset profiles started with 4 bar pre-infusion and it took the pressure all the way up to to 12 bars. The shots were perfect taste (not bitter) with lots of crema. I read that you can not expect to get too much crema in your shots unless the group head reaches at 9 bars of pressure. If this is true then why everyone here seems preoccupied on decreasing the group head pressures to 8.5 or even lower? Is it because they lack the pressure profile valve? I recently got my Synchronica with the manual pressure profile valve and I am learning to emulate what the M&V Vesuvius did automatically for me. I use excellent quality coffee (Onyx or Verve) and I grind my coffee using an Eureka Helios grinder. I adjusted the brew pressure to 10 bars, should do one more adjustment to reach 11 bar which is the highest pressure recommended to pull expresso shots or should I try to keep adjusting to reach 12 bars for more aggressive extractions like the ones my older machine featured. Am I risking my Synchronica doing that? What are the pros and cons? Will appreciate your comments

Another informative video Mark and crew. My non flow control equipped Synchronika, purchased from WLL, reads 10.5 bar pump pressure while brewing and I have never adjusted it. I wonder why it is 2 bar off? What is the optimal pressure, 8.5 or something a bit higher, say 9 or 9.5. We”re at 3400’ elevation.

Thanks for the video. Mine does not have an adjustable OPV. My machine has dropped to around 5-6 bars. I can lower it to around 3 but can not get it above 6 even turning all the way. Any ideas what is causing it?

Does adjusting the OPV lead to slower build up of pressure ? Trying to rule out my OPV since i've adjusted it to about 10bars from the factory hitting around 13. But my Shots with same puck prep seems to get up to pressure longer than it used to.

Quick question. What difference does it do to a shot thats running on 9bar vs one on 7bar?

Is it OK to do descaling by putting cleaning solution (citric acid) and flushing the whole system like on some other machines?

I’ve been seeing the pump pressure higher than the flow control pressure. 10ish bar at the pump vs 8.5 max at the group gauge. I have the flow set to 1.25 turns for roughly stock. I also noticed that at fully closed on the flow control, I still get water very slowly dripping out. Is that normal?

I am getting blind pressure of 10.5 bars on my ECM synkronika from whole latte love I bought a year or two ago and I never made any adjustments or modifications to my machine other than increasing brew temp to 205 F and steam to 271 F. Does this mean there is something wrong with my machine or that it wasn't calibrated correctly? 😳

When my machine is on the water reservoir it's at 9 bar when I plumb it in it goes to 10 even though I installed a 2 bar pressure regulator.

The pressure gauge needle are shaking. Is this a sign of opv failing?

On an ECM Puristika is the expansion valve knob sitting on the front directly connects to the OPV?

Any leads or links for vibe pump OPV adj. I have a 2004 S24 rancilio. Way different OPV

is more pressure counterclockwise or clockwise

When you guys sent me my machine I'm not sure what how many bars it was putting out but when I have coffee in the basket the flow pressure gauge is reading 10 is that too much I never touched it

Okay, now I have a question. My brew-group gauge consistently reads almost 1 bar (like 0.8 bar) LOWER than my pump gauge. (I put a picture of it on Facebook, but (sorry to say) I'm not very FB-savvy, so not sure how to link to that here. Or maybe someone can tell me how to post a photo here? Or I suppose I could take a quick video of it next time, and try to post that. Sheesh!) Thanks...

My machine is 10bar and I haven't changed it. Maybe a tad higher. Should I drop it to 8? That's 10 bar with the blind filter like u did. It's not 8-8.5

Doing this by yourself? Yeah, not fun lol. At all hahaha. Trying to slot a screwdriver into that little thing from underneath without bringing it to the edge like you did is about impossible haha. But, dropped mine down to 9 bar following this as it was at 10 and all working good. Lost a few lbs adjusting it HAHAHA

Could they make it any harder to adjust it? :)~
