Not to sound like too old a guy but, the primary use of a laundry outlet when I was starting out was for the electric iron, with the washing machine secondary.
Even today with the stackable washer/dryers an outlet for an iron in the area of the laundry equipment is needed.
Laundry circuit 20 amp. 120 volt.
The 240 volt circuit is the one that is NOT required.
