I assume that given certain conditions the kaleun would go anywere...
Imagine if most (read: almost all) torpedoes were faulty, I'd personally go along with the chief engineer and the weapons officer to the bow torpedo room to see what's wrong. I guess i'd go to the engine room if something serious had happened (u-505 coff coff) to assess the damage myself.
ps:
just because they didn't doesn't mean they couldn't
