Lol, I sure didn't make any mistake. I asked what code you were referring to since you seemed to be stating that the new dishwasher requires all wiring it connects to to be brought up to code. If I thought you were referring to j-box size, I'd have told you you were wrong to begin with.

Also, the "trouble" of opening mine up was three screws. What kind of lazy electrician are you, anyway? I told you you're making shit up, because you are. You're all over this post citing nec and so far you've been wrong more than you've been right.

Edit: I also just saw your other comment about the space required being 13.25in^3. that's not correct either, because you are assuming the clamp is inside the box, which it usually is not, especially on a small box. With a very common size being around 2"x2"x3", I'd wager that just about any dishwasher j-box is big enough or very close to it.
