Gaggia Classic Problem was created by Willwork4caffeine
Hi,
I have a Gaggia Classic that I bought second hand. When I first primed the machine it ran water through the steam wand and it produced steam fine, but I couldn't get any flow through the group head. I let the machine sit for a while with the steam and the brew buttons in the on position. That may have been a big mistake. I was confused about the directions. Anyways the no water through the group head problem was because the pump had become dislodged from the mount, which seemed strange because the water line did not seem to be kinked. I remounted the pump and the water flowed through the group head and I can pull a shot. When I primed the machine again water flowed through the steam wand, but now I cant get water or steam through the steam wand and the water just flows through the opv valve and back into the tank, but the group head seems to work fine. Can somebody please help me here?
Thanks

2nd hand...
Sounds like the machine is full of lime scale and/or the group head
holes are blocked.

Has it ever worked properly?

Have you ever descaled it?

According to the person I bought it from it worked just fine before it was shipped to me. He claimed that he only used it a dozen times. When I first tried to use the machine and prime it, I got a lot of steam out of the wand, but hardly any water in the cup under the steam wand and eventually the steam ran out. I wasn't able to get any water out of the group head. I let the machine sit for quite awhile with all the buttons on trying to get 3 or 4 ounces of water to come out in the cup thru the steam wand per the the user guide I found online. Apparently I never primed the machine and the steam that I got was just from water that was already in the boiler. I had not removed the top of the machine so I could observe that it was actually taking up water. I searched the internet for a solution and I found something about the pump becoming dislodged from the mount. Sure enough the pump on this machine had become dislodged from the rubber diaphragm on the mounting bracket, so I remounted the pump and primed the machine. This time I got water through the steam wand (no steam) like I was supposed to and then I could get water thru the group head. I was able to pull several shots and every thing seem to be fine, but then I could not get water or steam through the steam wand. I was thinking the maybe I fried the steam thermostat when I let the machine sit for an extended period of time with all the buttons on when probably the thing had no water in it. I don't know if the steam thermostat was totally fried if that would stop the flow of water or steam through the steam wand. When I try to get water or steam from it, the water just flows through the opv valve and back into the tank. It doesn't make sense to me that there is any thing wrong with the opv valve or the solenoid valve ( don't know if that valve has any thing to do with actually getting water or steam through the steam wand), seeing how I can can pull a shot. It doesn't seem likely to me that the steam wand or the valve is clogged when I got water through it so readily when I actually got it primed, but I suppose something could have broke free and it could be. So I am baffled and no I have not attempted to descale it.
Thanks for your response,
Jim

Likely that it has not been maintained properly.

Sadly, we need to take the "only used a few times" with a grain
of salt.

These are pretty robust machines - if packaged properly, they can
take a LOT of abuse.

I will be getting out the descale liquid and running numerous
cleanings sessions through it.

Do tell: Do you have an iPhone or a method of shooting some video for me?
