Good Day

Over the past week or more my LG Steam Washer is experiencing a problem. At the end of a wash cycle the Drum Light will stay on and as a consequence, I have no activity on the control panel. It does not light up nor will any of the functions work. The solution so far that has worked is to UNPLUG /PLUG the unit and then it will work again for a period of time. It could be one or two washes or work for more. There isn't any pattern. It is aggravating. i have researched the NET and found two possible problems.

1) it could be the Door Switch Assembly
2) it could be the motherboard

I have talked to a repairman and he said it could almost be anything but wouldn't rule out either of the two possible solutions. I am not interested in bringing a repairman that will change the motherboard to learn it was the Door Switch Assembly nor have the Door Switch Assembly changed to learn that it is the motherboard. So for now, i am unplugging / plugging it in
