Posted Fri Aug 10, 2012, 6:29am Subject: Gaggia Classic boiler broken after visit from electrician
A sad day for my Gaggia Classic....
The other day, an electrician was doing some work in my building, and he accidentally hooked up a 240v line where there should’ve only been a 120v. Not knowing this, in the morning, I made some espresso with my Gaggia Classic. Yesterday, everything seemed fine, but ...
This morning (after the electrician fixed the line), the machine turned on, but the water didn’t heat up; however, the lights and the pump still work. I’m guessing that the boiler is gone and I’ll have to buy a replacement, but before I do is there anything else that I should check to see if it needs to be replaced or do you just think that it is the boiler?

First off, I hope the eletrician is paying for any necessary repair or replacement.
Does the Classic have any sort of internal fuse? That would be the first thing to check. Beyond that, if there are any internal electronics of any sort on the Gaggia, they need to be checked. Your best option is to take it in for service and send the bill to the electrician (having told him in advance that's what you'll be doing).

Yeah, the electrician is going to pay for the repair, but since he is a good guy, and has helped me out before, I want to try and do this as cheaply as possible. I have no problems taking apart the machine & replacing parts on my own, I just want to make sure that I order the right part(s).
I will check to see if the Gaggia has an internal fuse, but I doubt it...
I was thinking the same think, and the diagram comfirmed that if the thermofuse blows it should shut off all power, not just boiler power.
Maybe you could get the electrician to help you troubleshoot the unit
If you take the top off, and look at the boiler, there are four pins that stick out of the top. This is the heater power. He can measure with a meter, and see if 115VAC is there.
If 115 is there, and no heat, then you need a new boiler.

Thanks you both so much for the information and the link to the diagram. I'll open up the machine this weekend and hopefully figure out exactly where the problem is.

Hmmm, I've replaced a fuse like that on my dad's Gaggia and only the boiler was out not the whole thing. The diagram does show that it should all be dead, but I'd still track down the power routing w/ a multimeter to be certain. This worked on his machine anyhow (it lit up and pumped water, but only pumped cold water). His was a "Coffee" not a Classic, these machines are darn similar inside but there may be a difference.
The fuse was from ebay for pretty cheap once you figured out the codes on it and which to get. I tried to look up the one I bought but it was long enough ago the link's gone.
If you absolutely must have a boiler I have some parts in the classifieds, as an option.
But I'd take another look at the fuse, it worked for him anyhow.

I don't know the Gaggia, but the Rancilio Silvia has a reset switch on the boiler. You simply access the internal parts of the machine, press a tiny red button and...voila...you're back in business.

Not a reset on Gaggia. You can check it with a DMM, or have your friend. You could also jump it momentarily, or your electrical friend could, if it is out and confirm that the problem is solved with continuity across the fuse/jump. For safety, I would not continue a jump but replace the fuse.
TracerBullet has seen enough that in spite of the diagram, he may correct.
