Decision when to turn off power on Silvia

Decision when to turn off power on Silvia

I suppose I'll have to pose my future questions with a preface: this
is not a debate between DH and myself ;-))

If one makes espresso off and on, say, from 7-1, and the next cup
after 1pm would be made around 3:30pm, would you turn off the power
for those 2-1/2 hours?

IOW, would one keep it turned on if one expected to make coffee in 1
hour, or 2 hours, or 3 hours?

Is it OK to keep power on all day?

Thanks,
Dee Dee

A stock silv?

Only iff you are willing to run the pump to refill the boiler about
every hour.

This is the Silvia I bought. Is it a stock silv?
http :// www .1st-line,com /machines/home mod/rancilio/silvia.htm

If I put a PID on it, will it still be a stock silv?

PS, Where the heck does the water in the boiler go every hour? Does
it evaporate? Nothing's leaking.

Thanks.

Re: Decision when to turn off power on Silvia

Howdy Dee Dee!
Yep, it's as stock as my first new car, a 1964 Plymouth Belvedere (hemi).
And like that car, your Silvia can be tuned to prodigious levels of
performance!

Would you pay a premium price for a car knowing the first thing you'll need
to do is take it in for a tune up? Well, that's exactly what you need to do
with your Silvia (Gaggia's w/OPV's too). The OPV is factory adjusted to ~14
bar; much too high for quality espresso (I prefer to set my machines to ~8.5
bar). That's another good thing about buying Gaggia's; members of our users
group have a group pressure gauge for everyone to make use of (members pay
only for shipping, plus a refundable security deposit).

Check the return line from the OPV to the water reservoir - that's probably
the most likely leak suspect in the Silvia. If it's warm, then the Silvia is
bleeding steam and/or hot water from the boiler to the reservoir. This isn't
usually too big a problem, usually happening only when the boiler is filled
to the top after drawing hot water through the wand. Excess water will bleed
off, but unless you have a bad OPV it'll just be a small amount.

The new Slivias (2006?), with the adjustable OPV are calibrated from the
factory @ 10 bar static, dynamic shot is approx 1 bar less @ 9 bar.

OMG!! what shameless gasbagging self promotion LOL LOL.

EVERY single silvia made in the last two years (and I've tested
hundreds of them as they leave here)

are right on the money at 10 bar. into a solid wall -- with no flow.

and as a further example , a NINE YEAR OLD SILV (in here for a 'pid'
installation) had PERFECT pressure at 9.5 to 10 bar.

No, and then it could be left on all day!

nothin' really needs to leak -- due to the vast temp swings in a stock
silv,

from approx 225 to about 280+ F at idle, a small amount of steam is
generated, and that forces a bit of water back to the white tank in
back -- on every cycle at idle.

thus the boiler dries out. NOT a good thing

Thanks for answering those questions in an understandable way for me.

Re: Decision when to turn off power on Silvia

Howdy Dee Dee!
First, does your Silvia have the new OPV & is it properly adjusted?
Second, does the steam wand leak - even a little?

As long as the answers are 1) Yes, 2) No, you're OK to leave it on &
unattended for long periods. The old, fixed temperature, OPV's were
notorious for leaking steam & hot water, which depletes the water in the
reservoir - same with a leaking steam wand. An empty reservoir causes the
temps to rise and if you're lucky the only thing that happens is the hi-temp
tstat trips (inconvenient, but an easy fix: remove the top cover & press the
red button on the hi-temp tstat). If you're not the lucky sort, the temps
rise until the heating element blows and you're out ~$140 for parts plus
shipping & labor (just one of the reasons some folks favor Gaggia's - over
heating's never a problem).

Bottom line: I usually leave my Gaggia Classic (shop) on from wake-up 'til
dinner. My Silvia (office), I only have on as needed (even with the 30
minutes warm up time) because Silvia boilers are too expensive & mechanical
tstats have infamous reliability issues. If you decide to take a chance,
turn the pump on once in a while to make sure the boiler's still full.

I use a timer to switch Silva on one hour before I need her first thing in
the morning, and then half an hour before other morning drinks. This timing
is based on the fact that Silvia is only stone cold for the first start up
each day.

I NEVER leave her on all day.

Cheers,
Rusty
