In general the o-rings that many are referencing are those to do with the solenoid valve and have been the source of many flow problems.
In some cases bits have also become dislodged and also become stuck in the solenoid.
As to references to CS, they are out of the loop unless a member visits the other forum and thus are not as in touch as some here might think.

Richard,
I don't know if anyone has verified that the Breville uses a Parker valve, however the internal seals are not O-rings. I think the o-rings that are being discussed are those used to seal the valve to the connector(s). So replacing the valve is apparently not necessary.

That's good to know, I wasn't relishing a rebuild of the valve. My machine is still working well and under warranty for another year, so I think I'll just hang on wait for something to fail before doing any dirty work.

The collar is made of a NON metal material and not unlike the hard plastic type compound that is used for the collar of many other cheep coffee appliances.
this should clarify where the o-rings are, vice internal seals in the plunger lest the two be confused. as i've been suspecting, an o-ring swap looks easy. f you were to do a gasket for the whole brass base, you would have to buy your own viton and cut it yourself, which could be pretty easy with some viton sheet and a set of hole punches. all kinds of gasket material is available for sale out there so you don't _have_ to use viton. obviously it would be best to get them from breville, but as imho, that will be easier said than done, at least here in the usa.
as for me, i'm still inclined to go with o-rings even if they last only 6mo- 1yr... at least until i get tired of changing them or motivated to make a gasket.

Okay, so my grinder is dialed in. 18g of coffee, and a 36g shot pulled in 31-35s using the manual shot delivery. Tastes very good as well.
My question is, can I adjust my 2-shot setting to deliver more volume? Currently, the 2-shot is delivering 34g shots (is it horrible to be 2g off of the desired 36g shot?). I believe it can be programmed, just can't remember how (perhaps I should RTFM).
The whole 18/36g thing is for reference only. There is no universally correct ratio. The ideal ratio is the one that brings out the best in your particular bean and roast. The idea behind weighing is so that you can make a record of what works and what doesn't and to help you repeat the good and avoid repeating the bad. Don't over think it. It's no more difficult than that.
And I'd ditch the volumetric presets... they have little value to the guy who makes 3-6 shots a day. Actually they do more harm than good in that environment.
How did you remove the insert? I tried using a chopstick for leverage to unscrew the spouts, but broke it :). Maybe a screwdriver would work better...
I can confirm that the VST 18g basket fits just fine (even with the plastic!). This is my first dual boiler machine and I've only had it since last night, but so far so good! Super easy to make great microfoam, and the espresso so far has been awesome. I am coming from a PID'ed Gaggia Classic with the Silvia steam wand, which I had tuned pretty well and was really in sync with, but the Breville is just effortless so far. Really enjoying extracting espresso at the same time as texturing milk.
My OPV is one that hasn't been calibrated. I extract around 12 bar so far. I'm planning on just opening it up and adjusting it myself, looks easier than when I had to do it on the Gaggia, and it has a built-in gauge to boot! The taste of the espresso was fine with the higher pressure, but I am a bit anal about this stuff (as evidenced by being a CoffeeGeek member :))
Looking forward to seeing other's thoughts on this machine.
Did anyone call Breville to ask with the plastic insert is for? I am looking into purchasing this machine or some other dual boilers. Do the owners of this machine find the steaming power adequate? Are you able to prepare 4 or 5 lattes in a row without issue?? Would you buy this machine again?
