Hello, I have been experienceing the same problem since I bought this thing. I used to have the classic Gaggia until it died after 15 years. however, when I went to this one it just didn't function the same.I was having water leaks come from the group assy so I replaced the group valve assy which I saw a diffrence and it functioned properly for a few days, then It was acting up again. No steam to froth and water bypassing the group assy... I then removed the valve assy again and saw it was somewhat clogged of mineral deposits.I cleaned it and after a few days once again it wasn't frothing as it should. Yesterday I completely tore this thing apart but couldn't figure out how to remove the steam valve assy. Does anyone have any ideas?? I removed the 2 screws and it won't move. OH BEFORE I FORGET!!! It was working fine the other day and while I was in the middle of frothing, it suddenly went to half pressure.... ANY IDEAS?? Thank you in advance....

I had almost the exact same thing. The fuse for your frother is out. If both the frother and the brew head won't heat, then it is your Thermal Fuse. There are two different fuses inside the machine. Take the top off, and find both fuses. Take a piece of wire and connect it to each end of the fuse. Now turn the power on. If it heats, then that is the fuse. If no results, try the other fuse. Either fuse should be cheap. My thermal fuse was $1.98. Good luck!

Pull off entire plastic wand off by unscrewing the top plastic piece. Inside the piece that connects to the screw top you should see two o-ring type spacers. The top one should be hard pastic and the one beneath should be rubber. Take the entire unit apart and clean, making sure to put all pieces back in the way they came out.
To put back on, take the top piece and put it back on the metal stem first then put the rest of the wand back on and gently push it as far up the metal stem as possible and screw back together. If you don't have the rubber spacer this could be the problem since the wand really has nothing grabbing onto the metal stem except for the rubber spacer. If this doesn't work, order another wand:

The solenoid valve is probably stuck (also called a three way valve). I wrote about how I fixed mine in another post. Here's a link. From there you'll find links to where you can buy a new solenoid if that's what you need. Good luck.
