Nice! Pretty simple eh? Sure wish that was a fix to just change the rubber

Exactly what happened to me. There’s plungers with springs in your group head
that prevent water escaping until you lift the brew lever. Now no longer

Hi guys,
Anyone know where I can get my hands on a replacement OPV for my brewtus.
Bella Barista UK seems to be out, Whole Latte Love doesn't seem to have
them as well and been looking at various parts sites and no luck. I am in
Singapore and the support for Expobar seems to be limited
Pump, OPV AND deaerator are new.
When you say Shotgun aprroach, I
didn't think this qualified as these are all connected components.

Hey guys,
I was having a problem with unstable brew pressure and I'm in the process
of replacing the pump, opv and deaerator. When I turn the machine on, even
before I reach brew temperature, water starts running out of the OPV line.
The brew pressure takes a very long time to reach pressure
set by the PID.
Set it at 88 Degree Celsius but it's measures as 91. Flushing was done.
Was the increase of pressure from the OPV causing it to heat up more?

2. If slow response time is not normal...my first guess would be a pump
problem? I'd think that an overpressure situation with the OPV opening
would show quick drops
into the deaerator valve so thats why there is a
continuous drip coming from there. Tech support tells me that this is
normal and to be expected.

something like 15bar to the opv, and the opv is bleeding off the excess to
regulate the pressure to where you set it.
On my machine there is no resivoir so the excess pressure comes out a little
down spout below the discharge of the group head. When I am brewing a shot
both a leaky OPV and then the
Ulka vibe pump. Since then, I am unable to get the brew consistent pressure
as I used to when I had the machine completely dialed in for beautiful
shots.
First, the pressure was varying up and down during brew cycle, and after
turning the OPV adjustment up

I set the brew pressure to 8.5 while brewing and the OPV is at 11.5. They were
set to 9 and 11 with a blank disc. Both are the readings on the stock gauges.
I have a portafilter gauge and it is very close to the machine gauges. Is
having the OOV open at 11.5 too high? Should I be resetting
I didn't intend to set it higher. I set both since my incoming pressure is 25
psi rather than 40 which is where the manual said it was set from the factory.
If 11.5 is too high I'd just open it and set it exactly to 11.
Thanks for the reply!

generally does than you should know if it's pressure. Also, if you're

are group gaskets, the screen under the gasket and the pressurestat

You can try adjusting the OPV valve in hope that an adjustment will get it
going. To do this put the back flush disc in, turn on the pump and turn in the
adjustment screw until you get to 10 bar. That should give you about 9 bar
