Some washing machines (especially older ones, newer ones not so much) draw a lot of extra power when they are starting up
(especially the spin cycle).  So that would have been a "slow blow" fuse, able to handle a momentary overload without blowing,
dedicated to the washing machine.  It may not have had a dedicated circuit back at the original main fuse panel.

Lessee, must've been about 1963, my folks were renting a house that had a fuse like that just for the washing machine.  It would
sometimes blow when Mom tried to wash too many clothes in one load (according to my Dad).
