George W Carrollton , MS May 26, 2016 Samsung washer would power up but not start cycle (3e code) Replaced door latch switch first----no change. Replaced circuit board and worked like a charm. This is the place to buy parts! I watched the diy videos and had no problems with repair. Took all of 10 minutes to replace both parts! This saved me a very expensive house call! 14 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
