  1. You could use one of those hamster drinking bottles, stuck to the side of the shower, and put the espresso into that.
  2. Success! The problem was around there, I'm not 100% sure which side of the elbow, but it is now unclogged. I had a terrible time trying to get the elbow off, I think it's loctite'd on perhaps? However, I noticed that when taking the input tube off, it released the pressure from inside the pump which should have gone out past the blockage (this was the residual pressure ~2.5 bar reading on the brew gauge). After failing to get the elbow off, I wondered... just wondered... if it was limescale then maybe having released the pressure I could get it to draw just enough citric acid in to dis
  3. A bit more progress... I've largely traced the water path, and I think the problem could be the same as the one on that Home Barista thread. The output from the pump immediately goes into a T, where the straight-on path goes into the brew pressure gauge (so the problem is after this, as you say @DavecUK). The other output from the T goes into an elbow, and then onto a tube (I think the joint from the elbow onto the tube is where the person in the Home Barista thread said their blocked gicleur is). Something like this: ``` Water inputs ---> Pump ---> T ---> Brew gaug
  4. I also note this thread https://www.home-barista.com/repairs/quickmill-vetrano-2b-no-suction-in-tank-mode-t45379-10.html which is a very similar sympton, and ends up as a blocked output nozzle from the pump. Although thinking about it, if the pump output were blocked, I guess I wouldn't be seeing the 9 bar of pressure on the gauge?
  5. Thanks @Catlady101, what a great find! I'll definitely bear that in mind when poking around inside the machine.
  6. Good thought @Markk, but I'm more convinced by the blocked or valve failed theory - mostly based on there being no suction from the water tank. Today I got distracted by another project, but I did get the sides off the machine and that lets me see a lot more. I intend to document the water paths, if I can see into it enough, and then figure out from the readings where the blockage / failure is.
  7. Ace, thanks again all. I’ll dive deeper tomorrow and see if I can figure out the water path.
  8. I just saw a third valve, up near the top of the boilers as well.
  9. Also, I don't know if this is relevant, but with the machine off then the brew pressure gauge is sat at ~2.5 bar - I'm sure that normally drops back to zero. It doesn't change when I lift the group lever.
  10. (I should also say to you both, many many thanks for pitching in on this, I really appreciate it)
  11. The machine always runs the pump for a second or two after turning on, and the PID does normally take a few seconds to boot - I'm not sure if those timings are related at all. It's weird that, in this fault scenario, the PID doesn't start booting until the lever is lifted (presumably it would turn on after the initial pump run, but that never finishes because the boilers aren't getting filled). When peering into the back of the machine, I can see 2 solenoid valves - I'm guessing that one of them is to control the "source" water input (and is next to where the piped water inlet and the ta
  12. No, no water comes out, and the pressure gauge doesn't change from the 9 bar reading. The only noticeable thing which happens is the PID boots. I've added a video of it to the Flickr album from earlier. I don't think it is Alberto, otherwise the pressure gauge wouldn't read 9 bar...which ties in with him not seeing water flow in the inlet tube. Exactly, I'm pretty sure the boilers aren't filling - there's no suction on the inlet tube, and the pump never stops after I turn the system on to begin with. I'd definitely agree that it's a blockage somewhere. I
  13. I've had a good look at the pipes as well, I can't see any obviously kinked, as far as I can tell behind the wires. The steam boiler looks a touch canted over to the left, but I don't think that'll've changed recently - I assume it's always been like that.
  14. Thanks for the tips, I've had a go at getting some photos / videos, you should be able to see them on Flickr at this URL - let me know if any others would be useful as well. Age = 6 years, although not heavily used in that time (weekend usage, not daily, and not every weekend either).
  15. I guess I was answering the original question, apols if it caused confusion. To yours, though, the closest I've got is the Made By Knock Feldgrind, which I do really like, but it's more of a travel grinder. I used to use it more before I had the NZ, mostly to avoid flushing the Zenith so much when switching between espresso and V60, but I use the NZ for that now. I also like being able to do other stuff (tare the scales, prep whatever the next step is) whilst the grinder is running. It's a small thing, but it works. Also I broke my shoulder a couple of years back, and although it's fu
