Pamela W Colorado Springs , CO June 05, 2016 Appliance: Model WDF510PAYSA Lights came on but nothing happened I replaced the main control board on my Whirlpool dishwasher. I found a step by step video online that was very helpful. This was so easy to do, glad I didn't pay some repair guy $400. I'm a 59 yr old woman, probably handier than most, but this was many first time working in an appliance. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
