It might be repairable, but it will take total disassembly, removal of all boiler parts, and an examination of the inside of the boiler to view the extent of the scaling. A thorough cleaning then examination by someone skilled at brazing (welding?). In the meantime, price a replacement boiler to balance against repair costs.

But the crack in the weld does look particularly ugly. It will depend on further examination, but I am not sure I would be comfortable using that boiler in the future even if repaired. I am not fan of household explosions.

Randy, could you look at the photo again.  It looks to me like it could be due to leak from an old or defective boiler gasket.  OP, I would scrape off the oxidation and see what's underneath.  Still a pain but you might only need to replace the boiler gasket.

The Livia 90 has a large flange on the heating element that is attached to the boiler using 6 bolts. This flange has a gasket on it and it is this gasket that has failed and is leaking, it would be very unlikely for the particular brazed joint on the boiler to have failed. Simply get the correct gasket and repair the machine for a few dollars and a little time.

It is the union between the plate that holds the heating element and the boiler vessel.

It appears to not be an active leak but it is or will shortly be a problem once I descale the machine.

Where is a good source for Pasquini parts?

Posted July 31, 2013 link

Would a clogged heat exchanger cause water to come out of the relieve valve on the front instead of the brew head?

I started a new thread for this issue:  "Why is no water going to brew head?"

but maybe it is just the same "too much scale" issue.

This machine seems to be covered in white deposits (steam wand, around the relief outlet, and inside the water tank)

The seam looked like a crack - sorry.
