Got the same issue, and tried the same thing (buy another stove on construction mode because I couldn't find any other way to proceed) only to come back and see the broken one back at its place.
Seems like a bug that needs fixing.
It's the second time it happens to me and I'm pretty sure that whole specific event is just bugged and impossible to resolve.
There's just no interaction with the broken object.
(spoiler: you need to use one cheat) what I did : go to manage worlds and then remove the stove or grill then go to the event it will say explosive malfunction but it will not say fix stove. Go back to manage world put a new type of stove or grill load back in. Now it will say fix a stove or grill but there is now only the new clean stove, use the cheat to break the stove and then fix, replace, or call maintenance, then the event will clear. Saying this next time don't go to exposition events till it is fixed use the call contractor thing.
