We followed the instructions in the video to remove and replace this part. Our dishwasher was hard-wired in, so I needed to disconnect the electrical cable to pull it out all the way and that took a bit of time. (With the breaker off, of course-safety first!) It was also very helpful to have a headlamp to see what I was doing, both under the sink and inside the dishwasher. If you're nervous about trying it, as long as you are familiar with using hand tools it's probably easier than you think.
