I am pleased to report that the initial testing with the new pressure valve is very promising. The pressure on this gauge is 10 bars exactly. I have been assuming that this gauge was 1/2 bar low in comparison to some others I checked it against using air pressure. If that is true, I have exactly 10.5 bars, but maybe Bill checked this valve before he sent it against something more accurate than my averaging method.

Bill: Just a note, the pressure rise with air captured in the PF doesn't seem to be any faster than the tests in the video, but the pressure is, of course, much higher and stable. Also, there is a little mineral build up around the top of the old valve which looks like it may have been leaking a bit.

I am anxious to re-dial my grind for the higher pressure and see if I can improve the shot quality. If you have been following my issues, I have been putting out bad shots from the beginning. I am hoping that all of that was due to the low to very low pressure I have had and that this is the start of new taste experience for me. I struggled for months before I hooked a gauge up. My advice to anyone that is experiencing issues that you can resolve is to buy yourself a PF pressure gauge.

Thank you Bill!

Hopefully you'll now be able to see the awesome shots this machine is capable of lol. That does suck though you went that long frustrated, if the opv was fluctuating that could have easily affected extractions. I would think you'd still want to be around 9.5, I know other machines that come incorrectly calibrated or at a higher setting people generally adjust to 9.5. That's the one thing I haven't checked on this machine, is the opv adjustable?

Well, at least I have a new problem I have not had before... now I can't get the grind fine enough. My coffee is a little old, and I have a calibrated tamper, but its pouring though like crazy now with 19 grams of coffee.  I guess I am off to the grinder forum to get help re-calibrating my V-W

I have a new package of Redbird that just arrived a few days ago, but I wanted to see if I could dial in this old coffee before I started on the new. The coffee I am using now is about 4 weeks old I think and I don't have too much left and I will be starting on a fresher batch.

I ended up disassembling the grinder and cleaning it and re-calibrating it. By the time I got it half way close on grind to use the 4 week old coffee, I ran out of coffee. So I started with the new coffee... sinked the first two shots with the new coffee. I have made two drinks with new coffee... both very drinkable, but sure I have got to experiment to find my sweet spot. The one I drank last night tasted pretty decent with just milk and espresso without my flavorings... but I still like my sweetened flavored coffee the best.

Machine is completely different with the new pressure valve. It's like starting all over again.

I am sorry you have had so much trouble.  But you have learned a lot and now should be making great coffee.

Dean,

Congrats on fixing the problem!

Where did you buy the pressure gauge?

Posted July 4, 2013 link

I just bought a gauge like this (http://www.espressoparts.com/V_512)  that screws on my PF. This may not be the best way to go for you. I always use a naked  PF which means I don't use my dual spout PF, so I just screwed the spout off of my dual spout PF and put the gauge on it. So far, I have just left the gauge on it.  If you have a standard PF you can buy PFs with a gauge already on them. I don't think the CC1 PF is standard, so I didn't order a PF with a gauge on it.

I use crossland's nude PF for shots and only use the spouted for backflushing. Would I still be able to backflush with a blind basket when the gauge is on it? Also, would the pressure reading still be reliable when the blind basket is in?

Have you come across solutions that may be more accurate? (like you, I do think that the CC1 PF is not exactly standard, so a different PF won't work)
