Nope, none of that stuff worked. Instead, no thanks to Samsung, I went and found a YouTube video that showed me how to get into diagnostic mode. I found the service manual online, but I had to pay so gave up that avenue. As a product owner I should be able to get the service manual. In any event, I found three error codes when I went into diagnostic mode. The first two, DC and DDC were errors we had seen recently- opening the add wash door without pausing the cycle, and once pressing start without fully closing the door. The last code was interesting. It has NEVER displayed on the screen, and it was DC1. We've noticed sometimes it goes through a few attempts before ultimately securing the door. I suspect that the lock mechanism is failing, because when we stand there and make sure it secures properly, we don't see the cycle being interrupted. I will be replacing the locking mechanism. I would add that, as a result of how hard it was to figure out the error code, that is not having access to the service manual and the code only showing up in diagnostic mode, I won't be buying another Samsung appliance. This is actually the second problem with this washer, and the matching dryer doesn't dry bedding, it turns it into a damp ball of sadness- every time.
