Try going back to basics. Yes, I've been caught out by something silly and obvious! Are they the correct OEM blades for that model? Are there washers/spacers fitted on the mount screws? Are they the correct screws? Have all the access covers and cutting guides been refitted correctly? Has the depth guide been set correctly?
Some planers can be fitted with thicker or thinner blades depending on the model. Washers/spacers may need to be fitted under the blades so they are 'trapped' and lift the blade high enough to clear the screws. Are the original screws 'dome head' or 'countersunk'? Domes will sit higher and touch the wood as the blade spins. The access covers, cutting guides and depth gauges could be out of position affecting the cutting platform.
Replace the blades. It sounds like they're pulling up the grain too easily rather than cutting it. (Its like when you shave with a dull razor blade) It could also be the species of wood and/or the direction you are running it through the planer.
It sounds like your blade holder assy has become misaligned on the blade drive shaft. Try if you can to use a straight edge on 2 planes 90 deg apart and see if there are any gaps in either of the srtaight edges. I suspect that the blade drive holder has become slightly dislodged from the drive collar on one end allowing the blade drive to tilt on the drive shaft. I had the same thing happen on another brand named Planer and it was a matter of reseating the collar to cure the stripes. Sure took a long time to sort out. Good Luck.
Are the blades turnover knives? If they are the easiest way to do it is to adjust the planer bed or seat to omm planing depth. then take either an adjustable (combination) square or steel rule, and hold the edge of it along the bed or seat and adjust the allen (Hex) screws so that the edge of the knife allows a piece of a4 paper to pass between it and the rule tightly. Do this both sides of the knives and you are done.
OK you need to go to Dewaltservicenet.com and in the middle of the page at the bottom type in your model number it will take you to another page and then find your type number and click on the instruction manual section on the right side, I clicked on type 2. This manual is about 30 pages long. Let me know if you still need help and if I have helped could you please rate the answer accordingly. Good luck
