Sounds like you hit a staple or a small nail and put a nick in the blade. change them out and retry run some wood through if its gone its a bad blade.

Unplug it and inspect the knives if the knives or damaged it must be replaced if they are not checked for the blades being in place correctly if they are not they must be readjusted

You might be able to shift them ever so slightly so that marks made by the nicked area of one blade will be repaired by the now shifted portion of the next blade. I don’t know if this works but I read it somewhere. It makes sense on the surface but it could have been a complete fabrication.

I have a DW735 for which I have yet to examine the cutter head assembly (I know they are completely different). I purchased an extra set of knives when I got it just in case they got damaged in the middle of a job. It has been such a long time since I bought them I expect that when they are needed they’ll be a difficult find at best. Those that believe in power tool voodoo will nod their heads ever so slightly.

CCweems is exactly right. Following instructions in your manual, loosen the bolts holding ONE blade, shift it ever so slightly to one side or the other (makes no difference which) retighten, and the defect will go away. Tje blades nolonger cut the same track, so they cut out the defect left by the others. Works eveery time. The blades are reversible too, so when they get dull, flip them.

While you’re at it, clean the rollers with mineral spirits and do it regularly to prevent slipping. Unplug it, of course, whilst doing any of this.

If you nicked the blades, you wouldn’t have a depression, but a “bump” the length of the board. So, what is it, a depression or a bump?

If it is a depression, look for a screw head that is too high, or may not be fully tightened. A friend had that problem when he put some aftermarket blades in his DW735 that were a little thicker than the stock ones. Apparently there isn’t much clearance above the screw heads.

slide the blades over slightly to cover the nicked blade. Otherwise flip or replace the blades.

I have to agree with Joe’s comment. A depression the length of the board doesn’t sound like a nicked blade. It sounds like something is protruding below the blades.

it would sure be nice if the originator would at least reply or let us know he figured it out I get pissed when people start threads then they never respond to the help that is being given maybe I am a asshole but it really pisses me off if you wanted help at least be kind enough to acknowledge that you got it or if we are going in the wrong direction

Dude,

Lighten up, man. It’s been less than 36 hours. Maybe he has to work, or sleep or——-

I have even seen a peace of wood split off and wedge in a planer and cause this.

If it is a DEPRESSION running the length of the board then mveach has the answer. A piece of knot or short length of broken off wood (as in grain run out at the trailing end of a board) can wedge in a feed roller or bed roller and cause a bruise mark or depression. In fact anything wedged in rollers etc can cause it.
I wish the OP had supplied a picture- a helpful answer would be had easier, instead of speculations or mantras…..
