The photo below shows the boiler still in the machine. You can see where one of the brass couplings has popped off. That is the hot water on-demand heat-exchanger. Water in it must have froze in transit, and the ice blew the top off the stainless steel flange where the coupling fit in. The coupling is still screwed in to the flange. The flange just isn't in one piece any more. The same happened to the heat exchanger next to it, which runs to the group head. In this case. the flange is split, but not completely blown off.
Here is the Lyra with the boiler removed.
Finally, a look at the boiler itself. The markings are my own, just so I don't forget where everything goes. I still have to put it all back together, assuming it is possible to weld the damaged bits.
I'm not going to get my hopes up, it's more like an interesting project now. I'll keep you posted .
