No Flow From Group Head, Wand or Hot Water Dispenser


Recommended Posts

This happened the day after I made chocolate milk for the first time using the wand so I’m highly suspect. But it was of course cleaned throughly and purged afterwards.

Out issue is the machine, with a full water tank, does not pass water through any orifice. It hums, presumably to build pressure somewhere, but nothing happens, ever, and this coffee is our lifeblood, so...any ideas appreciated.

I did factory reset and checked the tank / water carrier valve connector to no avail.

Have just sorted the exact same problem on a Sage machine that I picked up cheap on Facebook - solenoid was caked in limescale. Working perfectly after dismantling the valve and soaking in a citric acid solution. Provided you know enough to work safely on the machine there are plenty of guides available on how to remove the solenoid valve block - this is what I used for the Barista Express. https://www.youtube.com/watch?v=96IuKiuIB5A
