Your first big mistake at a new job is coming. How you report it is the part they’ll remember.

Breaking something is expected and reporting it is optional, which is why only one of them is informative. Everybody around you has broken something, so the error itself tells them nothing they had not already assumed about a new person. What they are waiting to learn is whether you say it early and clearly, or whether they find out later from somewhere else.

Decide now, while nothing is wrong, what you will do when it is. Straight to the person who can help, with what happened and what you have tried.
