The Apprentice star names the Walford serial as one of his pet peeves during an appearance on Room 101 next week, according to a report in The Sun.
Hewer is quoted as saying: "There is one thing I loathe and abhor about EastEnders, and it's the violence and aggression which seems to be threaded through every episode.
"And that violence over the years has leached into the British consciousness so that today this country is worse for it.
"I think EastEnders - God bless them, great actors, great storylines - just less violence please. You are doing us harm."
Hewer features on Room 101 on Friday, February 24 at 8.30pm on BBC One. Comedian Rhod Gilbert and presenter Carol Vorderman also appear in the episode.
