Recently, my washer has decided it won't turn on. When it happens, I can unplug it and plug it back in and it will function normally. It continues to work for a week or two, then it "dies" again. The same thing is happening to a friend's washer - same model purchased around the same time. I'd like to get ahead of the issue. Would running the diagnostics tell me anything if the washer is functional once it's powered up?
