Can a Dishwasher be installed underneath a Fuse Box?
Nope, and that cabinet needs to go too

Whoever installed that fuse box was completely ignorant of NEC 110.26's clear working space rules.  In short, there's a 2.5' wide by 3' deep by 6.5' high box, directly in front of the electrical equipment (fuse box in your case), that must be kept clear to allow service access to it -- no appliances, no cabinets, no shelving units, no garbage cans, no boxes, no dollhouses, nothing.
