Peering inside a steam boiler- anything wrong? (Spaziale A53 Lucca)

[TrippKnightly]

Here's a borescope video looking inside a non-working water boiler. See anything?

Boiler doesn't work/no pressure. Coffee boiler is fine. At time of failure there was metal taste from the steam wand but not the water spigot (we think). The steam wand may have its own issue since if anything I'd think the water spigot would exhibit more metal taste if the vessel is compromised? (The water output is much lower on the boiler body than the steam's output, which makes sense give where water vs steam reside.)
