2 entirely different things. You adjust the pressurestat for steam pressure.

I have watched the videos on Whole Latte Love on pressure adjustment of the 
pressurestat and OPV.  When would you choose to adjust the pressurestat rather 
than the OPV to lower pressure?

Thanks again

If it's holding 13 it's not defective.

amazing - thanks! just adjusted the OPV to about 10 bar when blind, and sure 
enough, the drain back into the tank is now flowing at a much higher rate, 
pretty close to the recommended amount! was a bit late to pull shots tonight, 
but will try tomorrow to see if it's any different! i'm also looking forward to 
the lower brewing pressure and hopefully more forgiving shots for this relative 
newbie :)

 

now that i've opened it up, I can also see how if i do need to replace 
anything, it should be relatively trivial.

minor update: I just did the pump check 
<https://www.youtubecom/watch?v=kEl-uNOC1P4> , and with the blind disc in 
holding pressure, I'm only getting a very slow drip from the return tube back 
to the water tank - not the 1 oz-ish in 12 seconds. This most likely suggests 
the pump is on its way out right?

 

The other difference I can see is my OPV is set to about 12 bar, so could 
lowering it cause it to behave "closer" to normal behaviour?

 

Whats unfortunate is I see during previous servicing, the OPV wasn't placed in 
a way where the set screw is adjustable from the front of the machine through 
the hole. So I may have to open it up to experiment further.

Re: vibration pump/OPV for brewtus III

2019-11-27 Thread jt123 
probably only adjustment unless it doesn't work. i had to turn it down 
quite a bit to get it to around 10-11bar. and since then the behaviour of 
the machine is a lot better!

if my understanding of the theory is correct, IF you had the right coffee 
dose/grind/tamp, you should be seeing about 9 bars during extraction since 
the puck would offer the least amount of resistance compared to the OPV. 
however if the puck offers more, then you will see it going all the way as 
high as what the OPV is set to. at least here is where you can see the 
adjustment is incorrect. of course the blind backflushing basket will be 
able to tell you the same thing.

but if you really had to replace the OPV, its not a huge job either. (i may 
just do the pump at the same time, or at least purchase the assembly so you 
have the pump on hand in case replacing the OPV by itself doesn't solve 
your problems)

RE: vibration pump/OPV for brewtus III

I think I am in the correct thread for this question.  As my pressure  is 13 
bar, how do I know if the OPV needs replacement or only adjustment?  Would 
adjustment fail if defective?

Re: vibration pump/OPV for brewtus III

2019-11-20 Thread jt123 
amazing - thanks! just adjusted the OPV to about 10 bar when blind, and 
sure enough, the drain back into the tank is now flowing at a much higher 
rate, pretty close to the recommended amount! was a bit late to pull shots 
tonight, but will try tomorrow to see if it's any different! i'm also 
looking forward to the lower brewing pressure and hopefully more forgiving 
shots for this relative newbie :)

now that i've opened it up, I can also see how if i do need to replace 
anything, it should be relatively trivial.

Re: vibration pump/OPV for brewtus III

2019-11-20 Thread jt123 
minor update: I just did the pump check 
, and with the blind disc in 
holding pressure, I'm only getting a very slow drip from the return tube 
back to the water tank - not the 1 oz-ish in 12 seconds. This most likely 
suggests the pump is on its way out right?

The other difference I can see is my OPV is set to about 12 bar, so could 
lowering it cause it to behave "closer" to normal behaviour?

Whats unfortunate is I see during previous servicing, the OPV wasn't placed 
in a way where the set screw is adjustable from the front of the machine 
through the hole. So I may have to open it up to experiment further.
