Annella K San Juan Capistrano , CA March 06, 2015 Our dishwasher is 16 years old i was concerned that the blades may be clogged because of the hard water the upper rack dishes were not as clean as they could be The parts arrived, I remember the video and did what I remembered. Done! it was simple and fast and I feel like this dishwasher may last a few more years. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
