Subject: At the end of the pull with my Silvia, I sometimes get a squirt from

A few weeks ago, I already posted the message below, but didn't get a
response. Hopefully you don't mind that I try it again.

Lately I noticed that when I end the pull, by switching off the
coffee/brew switch, a little bit of espresso is squirted from one of the
spouts, in that way that it ends up besides the machine on ther counter.
Could it be that the 3 way valve isn't functioning correctly anymore and
that I have to disassemble and clean it ?
Btw, every now and then I DO backflush, following the guide on RandyG's
website.

I've had my silvia for about a year now, and I only back flush
occasionally.. like maybe once every couple months. I don't really
think you have to do it all that often.

is the puck solid when when you get squirts?

The puck is solid and dry most of the times.
I think it was the 3-way valve. I backflushed with cleaner and descaled
today and after that it was o.k. again. Hope it stays that way.

not an expert, but can't you see if the 3 way valve is working by
attempting to backflush it?

if water does come out of the valve, then I wouldnt think it would be
possible for water to shoot through the puck when pulling a shot,
unless it wasn't packed very well and loose. (ie not enough pressure
for the valve to release?)

i dunno.. im just guessing

When I backflush, I normally see water coming to the drip tray. But
could it be that it sticks sometimes and that I should backflush more
often, if need be with water only ?
Btw, I use the Weiss distribution method to dose and distribute and then
pack with around 20-25lbs, still using a bathroom scale to keep it
consistent.
