Solenoid Valve on an Espresso Machine | What's this bit? 

Thanks for all that found this early this week as I have a non working valve. Saved me time in sorting.

Thanks so much for posting, this was very helpful in narrowing whats wrong with my espresso machine.

Thank you so much, I had doubts about this piece and now everything is clear!

Very useful! Thanks! You have de-mystified an important bit of my Espresso machine!

Many Thanks!!!! I "had" a blocked three way valve in a Larmazocco Linea (caused by too much cleaning agent in the group). Taken apart. Cleaned. Back together and working!!!

Thanks Peter, really clear explanation and helped me understand the issue with my machine. Great work :)

Very well explained. Many thanks.

Hey Folks, thank you very much for this information, is very helpful.

interesting stuff and you clearly know your stuff Peter. On a basic, single group machine, why would the pressure be going crazy, not settling at the typical 1.5 bar? I have checked the two release valves for cleanliness and lubrication... all seems fine, but switching back on sees the pressure go right round the clock until there is a massive release.

Your video is good. On startup, my espresso runs start/stop of about 5 to 10 cycles before it gets going. Is this how a failing coil would begin failure on my machine?

Nice... Good info 👌

Would a solenoid valve (3 way?) be the cause of steam coming out of the group head when I am in steam mode? Seems I have lost power in the steam wand and losing pressure and/or steam out of the group head. I have a Gaggia Coffee Classic.

Appreciate it used this info to fix a commercial steam machine

Thanks so much for you explanation. I cannot open the valve plunger. Seems like the lock is stuck. You have talked about a tool ( shifter) to open it . Kindly let me know what it is? I think there is calcification inside the plunger so my water is overflowing. I'm talking about the 2.02 part of this video. The part where you talk about opening the valve stem. Thanks in advance.

Thanks for the info. I am having a problem with my machine. The boiler is not filling. Pump kicks on but the water is being pumped directly out of the overflow. Could it be a solenoid issue? Any help regarding what could be the problem would be appreciated.

My Breville's steamer used to be a standard pump... pump... pump... pump, etc. but now it's doing pump... pump... pump pump... pump, etc. bit like an irregular heartbeat. The steamer doesn't seem to be giving enough pressure as the group head extraction and hot water pumps are working fine. Would changing the solenoid for the steamer likely fix the issue?

Is it possible to just change the solenoid the pice with the spring and the rubber inside the valve? Where can i find that pice?

Is it possible to show the internal parts of Nuovo simonelli appia 2 and some explanation about them and how to change them. Thanks

Hi Peter, great video. Im getting water thru the group head when group handle is empty (only the left one-right is fine), its less water than normal but when the grouphandle is loaded I get no water through at all. I can hear everything working as normal but just no pour. Could this be a clogged/dead Brew Valve/solenoid ( are they the same thing?).

Thanks for this Video,but where can get new solénoïde for water water of my fiamma expresso machine?
