Hey, I have been using color catchers on all my quilting material and on the finished quilts in my front HE washer. I put the color catchers in the lingerie bags (usually 2 of them) and I have had no problems at all. I think that the color catchers could catch and land in the giant rubber washer/like ring next to the door. I have had socks, handkerchiefs, hose socks, and an occasional washcloth get captured by the this rubber thingy. And color catchers get caught in there and then they don't do their job because they aren't in the washing area. Soooo, I always put them in the lingerie bags...no problems at all and the catchers really love reds and blues.
