Lisa B Hoover , AL September 12, 2016 Blinking lights on our samsung dishwasher My husband took the dishwasher apart and found the motherboard was fried. We ordered this part and it took no time to install. Once we installed it and put the dishwasher back together, the lights continued to blink in error, but once we powered it down via the circuit breaker and back on, it fixed it. Praise the Lord for modern conveniences like dishwashers! 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
