I'm bringing this thread back up as I've just got a new washer/dryer installed (well mostly). In the cubby where they are installed there is just one of the three prong 30 amp style plugs (there was a combo unit in there previsouly that just needed one outlet). The dryer plugs into this just fine, but the washer requires a standard US grounded outlet.

I'll be getting an electrician to get a new outlet installed and to make sure that everything checks out. But I was wondering, can some sort of splitter be installed to break that one 30 amp outlet down to one for the dryer and a standard outlet for the washer? A quick internet search didn't bring me anything so I'm guessing that's a no for multiple reasons, but just curious if this was technically possible.
