Samsung Waterwall stopped pumping water out (made a strange motor noise but would not pump). Warranty repairman came out and replaced pump- then unit would not power on at all. Have spent 4 months with warranty service coming out and replacing every electrical part in the dishwasher- panel, circuit boards, etc - machine still will not power on (although they were checking somewhere on the bottom and it is getting power). They are now sending check for replacement. I have a hunch that it is something with that original pump replacement that they never went back to look at (since that is when it lost power)- so while I am waiting on check I'd like to see if I can fix it. I have repaired washers, etc in the past with the help of this site so I might as well try Suggestions of where to start?

Thank You!!!

I didn't find the right solution from the Internet.
