Posted Sun Jan 5, 2014, 4:39am Subject: Spitting PF on Gaggic Classic
Morning (for some) all, I'm having problems pouring espresso successfully after frothing milk. I don't often drink lattes, but my guests do which makes it worse! Anyway, I can pull espressos relatively well, I've only just started out, but after frothing milk I go to make the espresso and every time the PF splatters and splutters, eventually settles, but the shot is ruined. I'm using the new Classic with standard pressurised PF and little black, crema thingy. Is there something I'm missing, doing wrong? Any help would be very much appreciated, because it's getting embarrassing now. Thank you.

If you've steamed, then your boiler is too hot. The water in the boiler is way higher than the boiling point. As it escapes the confines of the machines it is able to expand into steam which will blast through your portafilter. Bring the temperature back down to brewing temperature (Liquid water). Before putting your portafilter in, run water off through the steam wand or through the grouphead until it is coming out liquid again.

I brew and then steam. If you steam and then brew in Gaggia Classic you definitely have to fill the boiler. Steam will partially empty the boiler and it needs to be full to brew. If you fill the boiler in close time proximity to brewing in a Classic, you will have temperature problems. The boiler holds 105 ml and even moderate steaming may use 1/3 to 1/2 of that. There is no auto fill so you have to fill after steaming. Auto fill would still have temperature problems and would not work well, probably why not included.
