I used your video as my guide and the job was easy. I connected a string to the old tube and pulled it through just as the video shows. The video says that if you use to much tape the connect the new tube to the string that the tube could get hung-up in the door. So I fed a mono-filament fishing line through new tube and tied off one end to the dispenser tip. I made the fishing line long enough (about 3 feet more than needed) and taped to the string. Pulling the string and fishing line back through the door was smooth as silk. The time needed to pull out the old tube and pull in the new was about 5 minutes. Thanks fro your good easy to follow video. You will be my appliance repair source in the future, Ralph
