Well, I sort of wonder if it may actually end up being more than my quadrupled 15sec extrapolation but I'm afraid to test a longer time without either putting the boiler back together or figuring out which wires will turn it on without turning on the boiler as well. So I'll give it some thought and either test it tomorrow or attempt to put it all back together and see what happens!

And yes I absolutely learned a lot! It was fantastic too so thank you again! And I will definitely let you know what happens either way.

Ok so I started putting it back together which was a little bit of a challenge, but I found that if I took off the bottom of the machine I could take off the hoses where they attach to the water tank and essentially pull out the entire inner workings of the machine which allowed me to fit the nuts back underneath the boiler assembly. Phew! I kid you not I was almost finished- just had to reattach the front knob and put the top back on and as I was tightening the screw that holds the heat sensors onto the boiler it snapped off. I pretty much died on the spot :/ apparently it was only pressure welded to the boiler and my super buff tightening skills were too much for it. So I went and got my dad to see if he thought there was a way to reattach it. He said we might be able to weld it back on but isn't sure since the boiler is stainless steel. For now we attached it with a welding epoxy so that I can get it put together and at least give it a shot to see if the boiler puts out any water because if it doesn't then obviously I'll have to buy a new machine and we won't need to bother welding it back on. It takes 4-6 hours to completely cure though and obviously as it's pretty important I don't want to rush it, well, actually I DO want to rush it but I won't! If it does work then I suppose we'll look into whether or not we can weld it back on unless there are any other suggestions? I completely understand if not :) I'll let you know what happens!

Sounds like you are making progress, one step forward and two back :)  What broke off, a stud on the boiler?  I can't quite envision from the diagrams, but I believe that there is a stud on the boiler that holds a clip for the thermostats, and held down by a nut.  You were tightening a nut on that stud?  Epoxy is JB weld or high temperature equivalent?

Yes you are exactly right on all counts! Andit was jb weld quick setting epoxy that is rated to temperatures of up 230 degrees- do you suppose that would be enough by itself? I'm not familiar with how hot the boilers on these types of machines get.

Not exactly sure which formula you used?  Some is good to 300F, but you probably read 230F on the package.  Did the stud have a flange or did you just try to epoxy the stud end to end?  That would be a very small surface area to hold when buff girl tightens, even if temperature holds.  The boiler wall may well go ever 230F with steam, probably not on brew.

The slow stuff, original is good to 550F, if you need a redo; that would be if you can tighten and it melts or softens.

Yes it had a flange thankfully and yeah it said 230 on the package. That's great to know about the slow setting kind though!! I think my brother has one of those temperature guns, maybe I can borrow that and check how hot the boiler gets while I have the top off the whole thing anyway. Then if it seems ok maybe I can just keep an eye on it and take the top off occasionally to ensure it's still holding. If not I may look into the slow setting one- that'd be a heck of a lot easier than attempting to weld something so small not to mention stainless steel!

Try a few runs without steaming and see if fixed.

Brew stat is 105C or about 221F and steam stat is 125C or about 257F according to

Waahhh! I waited the full six hours and didn't even use my brute strength this time and it popped right off :( debating if I should buy the slow setting jb weld and give that a try or not. Hmph. :)

Not sure that anything will hold.  Not seeing the application, does the nut have to be more than finger tight?  Doesn't it just hold a spring clamp down, but not actually apply the clamping force to the stats.  Or nut holds the clamp which in turn puts spring tension on the stat?  Are you over tightening?

Before epoxy, I clean with light sanding or steel wool to the area and then wipe with acetone.
