I watched a video on how to make the repair. I went shopping for a new dishwasher, saw how much they cost and learned the delivery time, then decided to order a new wash arm mount and arm-spray for my 15-year-old machine instead of buying a new one. The parts arrived within a week. It was simply a snap-off and then snap-on repair. I needed a Phillips head screwdriver to unscrew and re-screw the original washing machine screw. So glad that I did not lose any of the old parts. I was surprised at the high shipping cost of the parts. The dishwasher works again!
