Wash one load, then dies on the next. Had to wait overnight before it turns on again. Strange!
Washer had 3 different circuit boards. One for the LCD touchscreen, one for the power button and the main board that has the power supply on it. Had no idea which board it was. Got the manual from Samsung. They had the worse service. Did not even ship out until 4 days latter. It was useless. No diagnostics information.
Had to guess. Cannot be the touch screen LCD because it still lights up and sometimes works. Can't be the power switch board because IC with low voltage usually don't go bad. Must be the main board. It has the power circuit and electrolytic capacitors. Both take high power, and usually go bad. Wife can't wait any longer, so took the guess. Main board plus power switch board since that was not too expensive relatively speaking. $200 all together.
Switched out the power switch board. Yup, still bad. Switched the main board. Bingo. Works good.
Thanks a ton appliancepartspro! You have great price and very fast service. Saved my sanity too. Wife was ready to harp on me every hour until is fixed.
