Hello everybody, I need your help. This may not be entirely related to =
home roasting, but I wanted to ask "closer to home" first. Please let me =
know if I am way off topic for the list:
My Silvia is showing strange symptoms. She is two years old, almost to =
the day. She works with Rocky who is three years old and was a demo =
model before he was purchased. Silvia was purchased from SM.
Let me start with all the variables that have changed, almost =
simultaneously:
First, I just bought a Behmor 1600 drum roaster. I have been roasting on =
air-bed roasters for six years and I needed a change, mainly on the =
quantity of beans. I was brewing some Puro Scuro, the fourth batch =
roasted in the Behmor, into second crack.
Second, I just changed Rocky's burrs. Before the change, absolute 0 was =
at -2 on Rocky's dial, and moved to +6 after the change. Mind you, I am =
using teflon tape on the threads. This has not changed.
Third, I backflushed, like I have done approximately every 2-4 weeks =
since the warranty on the Silvia ran out.
The symptoms were not observed immediately after changes 2 and 3. I had =
four or five wonderful double shots after I changed the burrs and =
backflushed.
This is what happened tonight: I prepared my double shot the usual way, =
surfed the Silvia and the shot came extemely fast and globby and airy, 2 =
oz in 8-10 seconds. I was at +5 on the Rocky, my usual setting. I then =
prepared my wife's decaf latte (Donkey blend, roasted to vienna+ =
[runaway second crack while learning the Behmor]). The pour was not =
globby and much slower, but still fast. Two oz in approx. 18 seconds, =
with crema lightening in color steadily, half way into the shot. I then =
proceeded to gradually decrease grind setting from +4 to +1(!!!!) on the =
Puro Scuro and noticed that the pour was slow and streaming (not pouring =
in drops) in the beginning and suddenly started pouring out, globby, =
fluffy and light in color. The finer the gring, the longer the slow =
streaming initial pour was, but the faster globby pour still happened, a =
little later each time. The +1 shot was all streamy but the streams =
became "slimier" in appearance when I expected the fast portion of the =
pour to happen. Silvia did not choke, as I expected her to do.
One last thing: While surfing the machine tonight, I heard the solenoid =
gurgling into the tray louder that usual.

Try an air roast with the same beans, I bet that you'll find that it's
all down to your roast. It took me quite a while to figure out that I
was IMHO over-roasting my beans with my Turbo Crazy roaster. You might
want to run a roast in the Behmor and pull samples from the drum as the
roast progresses. (I'm not sure if it will allow you to do this)
Otherwise you should consider doing a series of small roasts to find
what works better for you.
 
I was pretty slow to adjust my roast because I spent about a year and a
half tuning my Giotto espresso machine. Despite the roast process being
essentially the same, I've found some surprising differences in roast
quality. When I moved, I went back to my air roaster until I unpacked my
SC/TO. When I did, I found that my espresso suddenly had the qualities
that I'd been missing.

My instinct is it is time to descale - something may be globbing the
valves....
You might order some beanse from Tom to rule out your process; or some Illy
to rule out grinder too.
Good luck,

Erm, your description of the problem is a bit odd to read. You might
also wish to put a pressure gauge PF on and make sure that your
pump/pressure regulator/relief is in proper order.

The easiest is to start with descaling and then go on from there. Also get
in the habit of back flushing once a day with plain water and once a week
with Cafiza.

Dear Nick,
   This is from someone who just reads the emails.  I do not feel  
experienced enough to write but I do own a Silvia-1 year old and I  
use an Isomac grinder.  Backflushing once a week is a must and  
descaling I usually do every 3 months.  In the directions it says to  
top off the boiler after you steam  the milk which may have been the  
louder than normal gurgling you heard. I realize this sound  
simplistic but I like to start off cheaply first.  Also I use an  
iRoast2 and in response to sharing profiles I have made some but  
nothing to expertise I usually read or anything that I have made that  
tastes good. Thanks- Diana

Nikos,
I would tend to blame it on the roast, before looking into a
mechanical issue with your Silvia.  When I roast too dark (usually by
accident) I need to grind a little coarser.  (it would be a few stops
when I used to use a Rocky), so this may be the root of your troubles.
 Darker, oily roasts tend to clump a little more also, so you might be
having some issues with distribution.  (I don't know if you have the
doser version of Rocky or not).
Since you have the teflon tape on your Rocky, you must have had some
slop in the burr carrier threads,  and since you just had it apart,
I'd check that.  If you put your burrs to the zero point, you should
hear steady rubbing, and not an intermittent metallic
clink-clink-clink sound.  If you are getting and intermittent sound,
your burrs are not parallel, and I would try cleaning all the threads,
and re-doing your teflon tape. A little bit of grinds in those threads
can wreak havoc.
What you are describing doesn't sound like anything I can think of
that could be wrong with your Silvia,  though a cleaning and
de-scaling certainly couldn't hurt.
Good luck, and report back on your results.

Cafiza is not recommended for a dual-purpose single-boiler machine  
such as Silvia--use water or Cleancaf to backflush. You can soak  
parts, however (e.g., portafilter, baskets, spouts, screens) in  
Cafiza.  But definitely descale.

I backflush my Sivlia all the time using Cafiza, and the blind filter
basket.  You just don't want to put it into the boiler.  It's really
the only good way to de-gunk the brass under the shower head screen.
A good rinse after, followed by a discarded shot, and I have no ill
effects (after 4 years of doing this ~ every 2 weeks).  Descaling gets
done with Citric Acid.
I think the warnings against backflushing a Silvia are primarily to
keep the less-informed from burning out their poor little Ulka pump.
With a modified (or new-style) OPV adjusted to ~9 bar,  the pump
doesn't even stall when backflushing, but I digress from the original
topic.

Cafiza (or Puro Caff etc.) IS used to back flush Silvia and any machine with
a 3-way valve. Cafiza is NOT for use through the tank cleaning machines
without 3-way valve.
