How to replace Assy Pcb Main;Dam-R3-05,. I tried to buy a new board from a Samsung parts warehouse and was told that the board was unavailable and that the board was now obsolute. The dishwasher was only 3 years old .I talked to 1 of my friends and they told me to try Appliance Parts Pros. I called them and they had the board in stock and I could have it in 3 to 4 days. I ordered it and it was an exact replacement. Washer fixed. The people at American Parts were very courteous and gave me excellance service. 7 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
