Brenda T Fairfax , VA October 22, 2014 Appliance: Model GU250XTPT1 My dishwasher wasn't working 7 blinking lights I called a repairman out to fix the problem. He said it was the control panel and the cost to replace it would be $437.00 + tax. That was about half the price of a new appliance sooooo, in researching a new dishwasher, I saw a site for dishwasher repair. After a few hours of searching and reading I decided to do it myself. I ordered the part then procrastinated fearing something more could be a problem. Finally I did it - I had to buy an inexpensive screwdriver set but I completed the task. It took a little longer than expected because the directions on line where not my exact model. Yeah! I have a working dishwasher. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
