It was a bit more difficult than the video portrayed, and it took a bit longer than anticipated, but in the end, it worked! The part arrived even ahead of time and was exactly as pictured.
We had taken a picture of the old part before we unplugged it, and that turned out to be very helpful when plugging in the new part. I had called your parts department to order the part, and the lady answering my call also was a lot of help. Our dishwasher is nine years old and it would not have been worth it to call a service professional to install it because the service call plus the part would have cost half as much as I had paid for the dishwasher originally. So, thank you very much for providing this parts service.
