- This has GOT to be the best bang for the buck Mod you can do on your Gaggia Classic Pro, and one of the easiest. In this video, I show you how to install a 9 bar spring in the OPV. The result are smoother shots with less channeling, and more consistency.

One thing that I did differently was that I left the tube where it was. This meant that once I disconnected it, all the water just drained where the tank normally is and I didn't have any water get inside the machine. However, since the tube is fitted in pretty tight, I had to rotate part of it by hand to make sure it didn't get twisted as I unscrewed it. Great video though, the other videos I had seen were about 6-10 times as long and gave the same information.
Thanks for sharing your experiences!
Thank you for this. No one actually shows what the spring looks like inside. This is the guide I will follow when I do mine.
Awesome, thanks for watching!
This was a life saver for me trying to get a proper shot from a naked portafilter. I had massive channelling and coffee spraying all over the place. After replacing with the 9 bar spring, the shots are perfect!
Awesome! Happy to hear it! :)
I’m using the 15 bar spring but have the 9 bar arriving today. I had similar issues and it seems like this should solve them
@@jayfron6012how did it go?
@@jayfron6012 hi did this fix your issue? having the same problem with my stock machine
Awesome video! First one I see that was smart enough to just pull the hose up and out of the way rather than pull the hose barb out!
Glad it was helpful, Felipe!
thank you! that was so easy and I am already extremely happy with my first shot at 9 bar
Awesome, happy to hear it!
Trying that, I accidentally broke the insert for the red hose below. It definitely is something you should be careful with, given how thin it was and how easily it broke. Still a good video though
I’ve done this mod on a new Gaggia classic evo and when waiting for the steam pressure to build up I get a weird noise from the pump when it reaches to a certain point of pressure. And the pressure drops down significantly.
Any one here that has experienced a similar issue and knows how to fix it? Thanks!
Sorry, I have experienced no such issues...
dearest, sorry for the inconvenience but I have an important question...I purchased the 9 bar spring which will arrive shortly...but after replacing it, can I still use the pressurized filter supplied (the one with the rubber underneath) or do I have to use it exclusively one of the remaining 2 (i.e. single and double dose)??? and if it's possible what happens to the coffee if I do it? Thank you very much❤
what to do if the plastic part breaks?
Likes, appreciated and subscribed!
Great tutorial! Thanks
Glad it was helpful!
Thanks ..helpful❤
Fantastic video! Quick question, I have done this mod and it works like a charm but I’ve noticed since my pressure on the steam wand is dreadful…. Is there something I’ve knocked to cause this? Do you have any suggestions 😅
I haven't noticed any differences here. Just wait 10-15 seconds after switching to steam mode, then start steaming. Cheers!
Just changed mine yesterday and I noticed the same here 😢
Did this last night, immediately notice the difference - one question though, the overflow pipe seems to extract a little more water now. Is this normal?
Yes, because the extra pressured water goes back into the tank.
@@TomsCoffeeCorner Good stuff, thanks.
Thanks a lot, Tom!! Will do so!!🫰🏻
Have fun!
My spring got that rubber tip in it, which side should that rubber piece go towards?
The rubber part should go inwards first. Cheers!
How to know that we get to around 9 bar pressure after replacing the spring? We dont have the pressure gauge.
If you refer to my longer video, I measure the various pressures with the manometer: ua-cam.com/video/akqC1CZXUr4/v-deo.html
After installing 6 bar spring, my machine seems to be noisier and vibrate more. What could be the problem? I tightened the two rear screws.
Oh I don't know about that. If you put the original spring back, is it still noisier or not? Did you make sure the little black stopper is still inside the OPV? If that fell out, then all the water will be diverted back into the tank, and it might be louder.
@@TomsCoffeeCorner oh no i did not check that stopper but the machine works fine, just noisier et bit more vib. I can assume stopper is in, if it makes coffee properly? Thx for answering so quickly
I succeeded to reduce the pressure to 9bar by cutting from the original sping. (measured the pressure after with a manometer).
I wanted to reduce more, to reach 6bar, I've cut a very small piece from the spring, but now, the pressure is to weak :(. I'm not sure if it's related to the second spring modification or something bad that i did (i've opened the opv when the steam was activated. i forgot to press down the button for steaming). Could be this a reason for very weak pressure?
Funny story - I tried the same thing with the Dedica. I cut the spring shorter and shorter, until it reached a maximum of 9 bar. But when I went to pull a shot, it was way to weak. I think the issue is that although the spring will eventually reach 9 bar, it takes forever if you cut the spring. There is a reason it was dimensioned how it was. Shortening the spring changes the behavior of the spring apparently, not just its limits, but how it reacts dynamically to pressure.
I suggest just buying a kit. I think I have the springs listed in the description. Cheers!
I got a 10mm wrench but I'm having a lot of trouble getting off the brass nipple. Any ideas?
I think there is a Loctite kind of paste in the threads. If it’s hardened over time, you might need to apply more pressure to crack it loose. Be careful though, since the OPV is made of plastic.
Do you think it's necessary to apply some Teflon tape on the thread
No, I have not noticed any leaking. Most of these connections come with an O ring that is compressed for a good seal. Cheers!
I noticed that the center light doesn't come on, I don't know if it's the bulb or something else
Well, in my video the machine was off. Do you mean your machine? It should come on when the thermostat is made. If not, then check your steam thermostat. Cheers!
@@TomsCoffeeCorner yes probably
@@TomsCoffeeCornersteam thermostat ? Not ,i talk about the central light corresponding to the button for extracting coffee, it never turns on, if I turn on the steam button it lights up, after a few seconds, off again. I actually read that in the instructions I should wait for it to turn on and then take out the coffee ,but the light doesn't turn on
Oh sorry, the middle button is for the brewing. Yes, so that's the switch for the pump, and the light indicator when on means that the temperature of the brew thermostat has been met. If it never lights up, then either the LED is shot, or your thermostat is shot.@@Peppe73it
@@TomsCoffeeCorner yes maybe the thermostat,thank you
Between this and the Delphi 685, which would you recommend....and why?
Hey Snap, that depends on where you live and how much you want to experiment. The DeLonghi can be had for just €150 in Europe, and is a great machine to start with. So if you live in the EU, that is a good option first. If however you live in the US, where the DeLonghi costs $300, maybe just go right ahead with the Gaggia, since it runs $400 to $500, and offers a TON of modification possibilities, and a great community behind it. Thanks for the question! 🙋🏼♂️Tom
İs the spring you using a spesific one or a just smaller spring which we can buy any store?
It is smaller in wire diameter. I have links in the description, as it is quite a speciality spring.
Note: "Gaggia" is an Italian name and is pronounced Gawd gee uh. No French "zh" sound for the gg.
Are you Italian? AFAIK, "gia" is pronounced as one syllable, like "Giacomo"
does the ovp spring for 9 bar comes with the machine?
Nope. It's 12 bar
The original pressure of the machine is 12 bar and with this mod it is being reduced to 9bar? Is my understanding right?
Do you happen to know if this voids the warranty?
That is hard to imagine. The OPV was designed to be adjustable via the springs. But, just be careful when unscrewing the brass nipple, since some people have managed to inadvertently bust off the stem that goes to the boiler.
@@TomsCoffeeCorner thank you!!
Hey Tom, I unscrewed the brass part and a little screw came out on the end of the spring with a green circle on top of it, I just put it back on the new 9 bar spring and put it back in the brass. Did I screw something up? I didn't see that screw in your demonstration
That’s a good question. I didn’t see a screw on mine, but there is a plunger, possibly with a screw attached. This opens when enough pressure is there to compress the spring. So yes, you should put it back together as you found it. 👍🏻
