not naked pf but blind, use the rubber thing that comes with the machine, that rubber thing you used with the cleaning tablets. use that, read the manual how to do the cleaning proceedure and you will notice the pressure with it
I don't have a blind, just the rubber thingy with the hole in it that makes a squealy noise and hurts my ears and doesn't seal well enough to measure pressure. Tried to order a blind when I bought the mocheen but they were constantly backordered. I could try again.
I seem to remember somewhere on the forum a thread about making a blind using duct tape or aluminum tape or something? This forum is getting long and cumbersome to search.
Just how long have you had the BDB? (i.e. I am trying to see if you have an early model. My unit was purchased in Nov 2012 and I got a solid stopper)
Did the rubber stopper (blinding plug) make that noise from day one? (Here I am investigating the possiblity of a "failed/defective" OPV)
Have you discussed this with the Breville techs? (the wait is long but I have had several questions answered by them)
I can't believe that a unit could be sent out with the blind pressure set so low (IMHO) that's just wrong. And, yes, it is not impossible that you were shipped a defective unit. "Life" happens.
Also, I would cover the hole with a small piece of the "metalized" duct tape (and if you can't find a small hunk of metalized I'd just use regular duct tape) and follow the steps in the manual for cleaning EXCEPT don't do the cleaning cycle. Just use the programmed two shot button.
Push and hold it until the pressure gauge is "maxed out". That reading should be greater than 10 bar (atmospheres). Then release it.
You could then make the adjustment as per the you-tube video, but, if it's still under warranty, maybe call Breville??? Your choice, of course.
Anyway, best of luck, and keep us posted.
Cheers,
Dave
Don't forget to stop and smell the coffee...... er flowers!
Regarding grinders, I'm using the Baratza Preciso which is doing a decent job. Grind is consistent, often clumpy, but easily addressed with a little mixing. If I ever upgrade, perhaps I will go with the Vario, but I'm happy and still experimenting a lot with my Preciso.
On a different note, when trying a new bean, what should be the first parameter to experiment with, grind or dose? Once grind/dose/tamp are set in, I move on to temperature to get the best taste, so temp is definitely last on my list. I'm just having trouble assessing what dose to use on a particular bean. Perhaps this is a chicken/egg type of question, so any general feedback on individual process is appreciated!

i dont know if this is baratza's reasoning for not recommending it, but, metal heats up more than ceramic, and in espresso grinds, the grinds are more sensitive to heat due to higher surface area, compared to courser grinds.
OK So I viewed the OPV adjustment video and being a mere physician, I decided to undertake this easy 15 minute job. A couple of things. Do not drop the nylon locking sleeve into the machine innards. Particularly do not drop the sleeve into the innards a second time.
At this point, the gods in question grow tired of the useless human and the sleeve enters a parallel universe, never to be seen again.
I had the same problem. Impossible to hold onto the sleeve while you are unscrewing. However, if you ever had to send it back, I don't think it would be too hard to find a replacement sleeve.
Can anyone tell me what the recommended pressure is? With a blind basket, I get 11, and my shots are usually just above the top end of the recommended pressure range. I thought about adjusting it, but I don't know if it would make a difference. I've heard pressure isn't a significant factor in the shot quality, as long as it is high enough.
