Ben, i dont know for sure but the excess pressure might be forcing its
way past the solenoid valve. i keep mine house set to 60 psi and an
additional pressure reducer for my machine set to 30 psi for that
reason. on the other hand, you can preinfuse a cup quickly with high
pressure. Dennis

Hello all,
Man, this list has been pretty quiet lately. Everyone still making good
espresso out there? I hope so!
I've recently accidentally reduced my dose, and have gotten some great shots
from it. As an experiement, I've been leaving the timer on my grinder alone,
and only changing the grind to affect both grind and dose at the same time. It
has been an interesting training exercise, i.e. making me work with one
variable to affect two, and try to find the optimal setting. Kinda fun.
Anyway.
I have a B2 that is now either almost 4 or almost 5 years old (can't remember).
I've upgraded to the WLL PID and rotary pump, as well as plumbed in the drip
tray (not the Expobar version, but watertight in any case).
We moved to a new home in October, and I started having an intermittent leak. About
once every week or two, after the machine shuts off and cools I find a puddle of
water under it, maybe 10-12" in diameter (i.e. not a ton of water). I can't
find anything wet on the bottom of the machine when it happens, but haven't pulled
the case yet to have a look when it happens. All the rest of the time, it stays dry
as you'd expect.
As an aside, the new house has extremely high water pressure, 105psi at the
hose bib.
Any ideas on the source?
All the best for 2012,
Ben McCafferty
