Zara: You may have a colg in the tip. Take offf the tip and run the hot water through the arm and soak the tip in whatever is handy to clean it out. Milk can and does clog up tiny litlle holes like that even with the pressure of the machine. I would run water through the tip after each use and always soak it a bit after several. ginny
ok peter, who said I could spell and you are correct a " " in the tip would be difficult for you. ginny

This morning I turned on my Giotto, = came back a few minutes later to bleed the steam wand (per the users = manual) before pulling a shot, and nothing happened - no hiss, no steam. = The hot water wand works, the pressure gauge is normal (1 to 1.5 bar), I = can pull good shots, just no steam.

I was going to guess vapor lock - as in, turn it off and let it cool down for an hour; refill the water, turn it on and bleed the air from the system prior to letting it heat up... Hope you find your resolution...

It's probably a clogged tip. A good habit is to ,purge the system,blow some steam through the wand immediately after steaming milk.
I thought it might be vapor lock too, but it didn't clear when I turned the machine off and let it cool down and then started it up again. How do I bleed the air from the system if that is the problem? I'll also check the tip for clogs - I do purge the wand after I steam each time.
If it's not clogged up wand or tip it almost has to be the valve. These valves aren't usually too difficult to rebuild, and many of them can be put back into operation using parts from the local hardware store. Then order the OEM parts and replace the temporary fix later. It is frequently a hard rubber valve disk that is loose and pieces plug the port going to the steam wand, or something similar. If you can post a fairly close up picture of the valve (machines body work removed obviously), I'm sure someone on the list can help you through the fix.

Here's a bizarre thought. Knowing where your Giotto & HotTop came from and since you're experiencing problems with both, and knowing both were checked out by Les before being sent to you, maybe Alfred misses his coffee toys and is hanging around playing tricks on you. Maybe, just maybe the fix is Who ya gonna call, Ghost Busters! Kona Konnaisseur miKe mcKoffee Who'll have that theme song playing in his head the rest of the day...

<Snip> ya <Snip> That is too funny! I've actually been trying to get to the point where I can make a good cappuccino as Alfred did - I'm not quite good enough with the steam wand to get the milk right yet. I must have been practicing too hard, because the wand was plugged with milk inside although it wasn't obvious and I thought I had been keeping it very clean. Once I cleared the obstruction, steam started pouring out like crazy again. The Giotto is a fabulous machine- great crema, non-stop steam (except when I plug the tip), very stable temperatures. I'm just not quite worthy of it yet.
having a colg in the tip would like be really really bothersome! PeterZ ginny wrote: <Snip>
To bleed the system of air, just turn it on, engage the steam valve early, and empty 2-3 oz. into a cup; close valve. Do the same at the brew head. At this point there should be no air in your system, and thus no vapor lock. Let it warm up, and start the espresso dance!

Adding to Ginny's excellent advice, I would say to use a pipe cleaner once in awhile. I do for my Silvia and it's clean as a whistle... A. <Snip>
