Jennifer W Belvidere , NJ April 10, 2015 Blinking led's on samsung dishwasher Looked it up on Parts Pros and found the cause and the required part. When the part arrived it took me about an hour to install it. Most of the time was removing/replacing the dishwasher itself. It's been working great since. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
