Sentence: Fred was supposed to run the dishwasher, but he put it off,  because he wanted to watch TV. But the show turned out to be boring, so he changed his mind and turned it on.
 Reason: The 'it' refers to the dishwasher because when the door is closed, a washing machine is often heard on the other side of the wall. 
 Question: Is the above reasoning correct or wrong?
