Hi. I am new here and I think my Silvia is having a midlife crisis.
I have had it for 7+ years and i would estimate its maintenance regimen to adequate, descalling a couple of times a year.
I just replaced the portafilter and screens around new year. I assume this machine would still work for 5+ years.
Last week it stopped sending water to the portafilter. Water would go easily to the steam wand, either as hot water or steam.
I didn't want to take it in (I live far from a service center). So I youtubed a couple of how to videos and took apart the entire thing.
I took pictures along the way to make sure I would put all back together.
After taking apart the boiler, I found a good amount of what looked like gray-black sandlike substance at the bottom. I removed all that obviously, assuming it was water residue.
I also took apart the 3 way valve, cleaned it up.
I put the entire machine back together (i have a spring left, not the one from the 3 way valve), but i think it's supposed to go next to the copper tube that connects the steam wand to the boiler, but i am not sure, so I guess my first question is, where does the spring go ?
but my main problem is that I think i accidently broke the thermostat. the connector that has a little red breaker. the red button broke off, and now the machine works, i get water going through the portafilter, but its too hot, regardless if i put it on steam or not. It's like it's on full boil at all time.
the symptoms telling me something is wrong, beside the fact the coffee comes out boiling ;) is the return tube in the water thank is now functionnal as a humidifier, as it spouts steam non stop. Also, the machine get real hot.
Needless to say, i turned off everything and am i now shopping for a replacement thermostat.
Does it sound like i understand what is wrong, or would someone be so kind as to help me figure out how to fix my machine .

There are only 2 non-pump springs in a Silvia, one inside the solenoid valve and the one inside the overpressure valve (the one you've got "left over"). Replacing the overtemp thermostat is well within your budget.
Replacing the thermostats makes very good sense, and will hopefully resolve the problem. If not, post again here with some additional information about the behavior of the orange indicator lamp next to the main power switch. This light tells you when the thermostats are calling for heat and is very helpful in diagnosing temperature problems.
