Fascinating, I don't think I ever heard "whitegoods" before. In case I'm not alone: refrigerators, washing machines and the like, in UK English. I think.
That's right, basically kitchen appliances, although fancy lads have separate utility rooms for washing machines and tumble dryers, and they often come in white so I guess the term stuck.
So like this:

But maybe not this:
