So, I purchased a new Gaggia Classic via the mail. After taking off all the packaging I attempted to prime the pump and get no response from the machine with it plugged in and all 3 switches on (no lights, or noise from the pump). Other posts I've seen have indicated the thermal fuse on the boiler is the likely cause, but I was skeptical since it had not been run so I opened it up to look inside.

I first noted that one of the leads to the power cord was disconnected (downward arrow - Eureka!) ... clearly the cause. Upon further inspection I also noted that a probe which I'm guessing is a thermocouple to the boiler was also disconnected (probe in hand, hole circled with horizontal arrow). This doesn't seem to just fit into place and would seem to require soldering. Does anyone have any advice on how to handle this? I'm hesitant to just try to send it back as I live in Japan and this would be difficult.  

I have not attempted to run the machine again as I am also hesitant to do so until I resolve  the probe.

Thanks for any help.

Hi, welcome to CG.

You knew the obvious answer, send it back :)  Since that does not seem reasonable, you could start here

http://www.partsguru.com/GaggiaClassicCoffee.html

There is a parts diagram and appropriate wiring diagram.  The photo is not quite large enough for me to clearly make it all out, but looking at the parts diagram, and knowing my machine, it seems that you have a wire to the element.  There are two elements on a Gaggia in the sidewalls of the boiler and terminals on each end, so, four terminal posts looking up at you.  If I am correct you can easily identify  the other three. I can't tell what is on the end of the wire.  As you can see, the wires have a terminal and connector covered with insulation, whitish.  I think that you are holding that.  If broken, you will need to figure a repair, or figure another connection.  If it all comes off and is broken, it can be solved with a tight fit slip on connector and insulation, making a new solder joint to the wire and slipping it on.

If you have a bare terminal, use a micrometer and get the diameter and we can help from there.

Hope that helps.

Thanks for the reply. Looking at the wiring diagram it definitely seems to be one of the 4 terminals to the 2 heating elements on the boiler. The entire probe portion remains connected to the wire. The new picture shows the wire with probe attached and the whole which it should go into next to the other terminal on the same heating element. So should I try to get ahold of a micrometer to measure the diameter of this probe? Thanks again.

(Note the pictures show up more clear when you "click for a larger image." I think my dimensions might be a little off standard as I have had to crop to get the attachments less than 75kb.)

I'm sorry to say, you can't just push it into place, as it will make poor contact and burn. You can't solder it in as it would be shorted to the boiler.
Contact the seller with the pictures. You'll need a new upper boiler (Containing the element that's obviously defective in the picture).
