Topic: Turning Miss Silvia On (4 msgs / 80 lines)
1) From: JB Christy
Does Miss Silvia typically stay on 24x7?  If not, how long after you turn it on
are you ready to pull a shot?

I don't leave her on 24x7. I do leave her on for long periods on the
weekend. Often all day. Weekdays I turn her on when I get up, off when
leaving, turn on when I get home and off before bed. I don't really remember
warm up from dead cold. She's been turned off for about 2 hrs, just turned
her on, boiler temp ready light out at 2:02. I think on first in the morning
a minute or two longer. However, on first temp up I never pull a shot.
Boiling temp is up, brew head & portafilter be heavy metal and are not! On
first session usage from cold power up, I always pull a blank through the
portafilter until temp light low comes on,  then wait for it to come ready
again, pull another blank. This ensures not only the boiler but brewing
group properly up to temp. Only necessary from cold start of course...

You should not leave Silvia on 27/7 and if you do leave it on during the day 
time you should make sure the steam switch is not on.  That will keep the 
boiler at a super high temperature.  I find that Silvia has to be on at least 
an hour to pull a decent shot however the Coffeekid has some methods on his 
site to "cheat" the warm up time on the Silvia and get a good shot with a 
short warm up.  I find that part of the trick is to make sure that one way or 
the other the portafiler is hot before you pull the shot.  I have a instant 
hot water wand on my sink and if I am in a hurry I will run the empty 
portafiler under that for a few seconds and then dry it with a towel before I 
tamp in the coffee.  If Silvia has not been on very long you can also heat 
the portafiler by turing on the steam switch, running a steam shot through 
the portafiler, then flipping off the steam switch and running water through 
the machine until the boiler light comes on.  While the boiler is heating 
back up to shot temperature, grind your shot and tamp it into the hot 
portafiler.  Once the boiler light goes off, go ahead and pull your shot.  
Running water through your machine is always a good idea before you pull a 
shot anyway as it accomplishes two purposes: It makes sure there is enough 
water at the proper temperature in the boiler to pull the shot, and it helps 
to keep the group head free of old coffee grounds.   Isabel
