You can add a PID and automate it too using an arduino or an ESP8266 to add wifi control.

Gaggia should offer the kit version of their Baby.
Caution! Water, heat, pressure and electricity don't mix! I want an espresso.

Unfortunately there was not bliss in paradise...

When I was cleaning the boiler, I saw what looked like a hairline crack on the front flange, behind the two mounting bolt holes. I slathered a little food-grade silicone RTV onto the boiler face and loosely bolted the boiler on to let the adhesive set before applying torque to the bolts. I tightened the bolts an hour later and then tested the machine the next day. Upon heating up, water POURED out of the boiler between the flange and the vertical boiler surface at the front.

Upon disassembly, the RTV revealed the depth of the problem. The boiler easily came off of the group, but the front portion of the boiler flange stayed behind, glued to the group :x

So she needs a boiler. JB Weld did not work. Tried it twice. Baked the boiler to evaporate any water from the pores, cleaned with acetone, clamped it in place, ground the mating surface flat, applied a liberal second coat. No difference. It's broke. And with JB Weld in the crack, welding is out of the picture. $45 for a new boiler is not a big deal, but makes it a toss up of whether or not it's worth fixing... It just isn't worth enough in good working order to warrant the expense unless I was going to use it daily, which I won't.

What do all y'all recommend, part it out or sell it cheap for parts? I hate to see it die as it's well thought out and an easy machine to work on. Anyone have an extra boiler laying around? :P I don't really feel like boxing it up and shipping, so I may just throw it up on Craigslist or FB Marketplace for a song.

Oh, well. They can't all be winners, right?

Cheers!

Bummer!

The boiler price is pretty cheap (~20 usd), but without any gaskets or pipes. Since you have all that, you could buy the boiler alone from wholelattelove.

Crazy deal... All I could find was $45 shipped on the 'Bay.

Thanks again, she'll live to brew again!

That's a great price! BTW, the Baby's looking good. The older Baby Gaggias are so much better quality than the newer (now discontinued) ones.
