Which logical fallacy is used in the text?
Right after Edgar moved into the apartment, our washing machine broke. He'd better tell us how he broke it.

 - ad hominem: a personal attack against one's opponent
 - false causation: the assumption that because two things happened together, one caused the other
The text argues that Edgar is responsible for the broken washing machine. However, the fact that the machine stopped working soon after Edgar moved in doesn't necessarily mean that he caused the machine to break. This illustrates a type of logical fallacy known as false causation.
