I doubt that the wiper motor and the washer pump motor share the same fuse - they might do but it would be an odd thing to do - to design it like that.
The common theme might be the switch - it may be that the switch-stalk controls both functions of wash and wipe - it could be that no power is getting to the switch stalk. Wire fallen off - switch broken inside.
I am not qualified to offer any advice on this subject - no skills or experience - just blind guessing - sorry.
Others probably know better
Good luck...
