He was given a violation of the code for training, a penalty point for racket abuse and a penalty of the game for calling referee Carlos Ramos "liar and thief" and insisting that "you owe me an apology".
Williams insisted that coach Patrick Mouratoglou had not been training her despite the fact that the Frenchman told ESPN that he had it and that all the coaches do.
"I just sent a text message to Patrick, saying: What are you talking about? Because we have no signs, we have never discussed the signs," Williams said.
Williams said that players are treated differently than their male counterparts in sports.
"I've seen other men call other arbitrators, I'm here fighting for women's rights and for women's equality," said the 36-year-old woman.
"For me to say 'thief' and for him to take a game, it made me feel it was a sexist comment.
"He never took a game from a man because they said 'thief' … For me, it makes me lose my head, but I'm going to keep fighting for women."
Williams made reference to the incident last week when French player Alize Cornet was warned for taking off her shirt on the court.
Cornet was accused of "unsportsmanlike behavior".
"Cornet should be able to take off his shirt without getting a ticket, this is scandalous," said Williams, enthusiastic about her subject.
"I just feel that the fact that I have to go through this is just an example for the next person who has emotions, and wants to express himself, and wants to be a strong woman.
"They will be allowed to do that for today, maybe it did not work for me, but it will work for the next person."
