Hi guys, just registered and my first post here, I have just bought a 2nd hand Gaggia Evolution, everything works fine except that when i switch on the steam function, waited for it to heat up properly, and when i turn the steam knob, it produces steam for about 15-20 seconds, then no more steam comes out of it, just hot air. I'm not sure if this is normal since i used to have a cheap Breville Cafe Roma that can keep producing steam until the reservoir runs out.
I've opened the case and checked the internals, i can still make hot water come out from the steam wand no problems when the brew function is turned on, but when i switch it to the steam function, it doesn't seem to suck up water from the reservoir as well, that might be why it runs out of steam really quickly and just spits hot air out. Also during the heat up process when i switch on the steam button, i see a lot of steam coming out from the brew head as well.
I did a bit of research, it might be that i just have to descale the machine, but i have taken out the steam wand and soaked it in warm vinegar water to clean it, and the hot water does come out from the steam wand without any problems.
Another possibility i've come across was that i have to change the thermostat for the steam wand, but as mentioned earlier water doesn't seem to be sucked from the reservoir through the pipes and into the steam valve when i switch the steam button on and turn the steam knob.
I'd appreciate greatly if you guys can help. Thank you.
