Subject: New Gaggia Classic - is it working ok?
Hi all,

Been a while since I was on here, when I had a new Gaggia Carezza and
was learning all the basics.

Well now I have a nice new Classic - but is it working properly? For
hot water I fully open the steam valve (steam switch is not on), wait
for a few seconds to allow the small amount of steam to escape, and
then switch on the brew switch. The problem is that as much water
comes out of the brew head as comes out of the steam wand. Shouldn't
there be water out of the wand only?

Also, how much water should come out of the pressure relief pipe into
the drip tray on turning off the brew switch? I get just a little,
maybe a teaspoon full though I haven't measured it.

Many thanks.

Thanks. All working ok now - I even spotted the brew and steam switch
together sentence in the manual. :-)

Hi Stuart,

Thanks for the reply - I'll try with the steam switch on as well this
evening. Was this info in the manual, I didn't spot it?

Recently I read somewhere on the forum that the pressure relief pipe
only ejects water from between the pump and the valves, and does not
remove water sucked back from the puck, is that correct? The puck has
a pool on top if I have tamped quite hard.

I noticed a difference from using my Carezza as well - for the same
amount of beans ground and tamped, I get more contact between the top
of the coffee and the machine. Perhaps the portafilter sits a little
higher. But I wonder if this might lead to it being easier to block up
the machine, for example the holes in the screen ("showerhead")
because the coffee is in contact. Although I imagine it all tends to
get blasted around when the water hits anyway.

The 3-way valve just relieves the pressure in the brew path.

After brewing I leave the portafilter in the machine while going on
and steaming up the milk. After I finish with the steaming, then I
remove the portafilter. By then, any water left has been absorbed by
the coffee puck and it knocks out easily.

Turn both the Brew and Steam switches ON to get water out of the steam
tube.

No. The whole point of the three way valve is to relieve pressure in
the portafilter so that you do not get hot water and coffee blown over
you if you are making shot after shot.

You have to turn on the steam switch as well.

Sounds OK. Amount depends on many variables. Fresh beans, amount of
tamp pressure, how fine the grind is etc. As long as the three way valve
is not blocked it is unimportant. When you backflush it will be obvious
that everything is ok in that department.
