Subject: Rancilio Silvia leaks at the grouphead
When my machine sits idle (with the portafilter in place), steam/water
starts to drip out of the grouphead. Why does this happen?

Also, when steaming milk, I get a horrendous squealing sound. Does
this mean I don't have enough steam pressure? I wait for the boiler
light to turn off but it doesn't. Strange thing is when I turn off
the steam function, so does the boiler light. When I turn on the
steam button, the boiler light turns on.

Help for a newbie is greatly appreciated.

Ummm, yeah, Randy. And stay home from work the day before you get
sick, too.

;-P~

Seriously, there are ways to do that. The easiest and most accurate
(iigc) is to get a cheap digital thermometer like:
http://webtronics.stores.yahoo.net/digtherwkpro.html
...and use a washer thermocouple on the boiler. You will quickly learn
at what temperature the thermostat turns off the heating element and
can start steaming a few degrees before that.

The best way is a dual-setpoint PID that allows selecting a steaming
temp. This does not get you any more/better steam (for the most part)
but it eliminates the race against the thermostat.

The cheapest, easiest and most relaxing way is to drink straight
espresso and not use the steam function! :-D

Thanks.

I cleaned out the grouphead last night and wiped down all the water
under the machine. I turned it on again this morning and will see if
I still get the leak.

The water under the machine is a different problem from water leaking
from the grouphead, unless the machine is tilted and the water is
running off the drip tray.

If both hoses are in the water tank (there should be 2) and the drip
tray is not overflowing then there should 'never' be any water under
the machine. Water under the machine can come from a loose
fitting/connection, cracked hose, leaking boiler seal, cracked pump
housing, or leaking steam valve.

The formula is water + electricity = death

If the portafilter is dripping water out of the spouts when the
machine is sitting idle (and assuming that the PF was dry when
inserted) then the problem is probably a leaking 3-way valve. If
backflushing does not solve the problem then the 3-way needs to be
disassembled and examined/cleaned. If this is a new machine then
warranty work is.. err.. warranted.

No.

You should begin steaming just BEFORE the boiler light turns off. Once
the milk begins to swirl, open the valve about one turn or so and
adjust the tip's depth so that the screaming stops, but so that it is
drawing in just a small amount of air without making big bubbles.

That's because that is the way it is supposed to work. If you
understand schematic diagrams take a look at my website- in the
right-hand column there are a number of Silvia resources. If you don't
understand schematics, then don't look at the diagrams and realize
that your machine is functioning normally.

Any clarity on general leaking is helpful. i looked under the machine
and counter top and noticed there is some water under the
machine.....is this normal? Also, back corner of the machine near one
of the "feet", there is water collecting on the corner.....

leaking at the rear of the machine, absent an overflowing drip tray --
MAY be caused by a leak at the outlet of the pump -- usually where it
threads into the body of the pump.

Take the rear cover and plate off and operate the machine, it is easy to
spot.

Thanks! Any tips on the lead in the group head? I just cleaned it
and opened the steam wand, seemed to help but if I look under the
machine, it's dripping water somewhere and out on my counter top.

The screaming sound stops as soon as you bring the tip of the steam
wand to just below the surface of the milk and start creating foam. If
you keep the tip burried under the surface you will hurt your ears. Do
a search of milk steaming or milk foaming on YouTube or Google Videos
and have a look at how it's done.
