You can, but that case is extremely weak.
Have you ever walked into a room, smelled poopcorn and searched around for it because you wanted some but couldn't find the popcorn?
Did you fail to find the popcorn because it never existed? Would you say your failure to find it means your olfactory system is useless? Would you say you failed to find it because your eyes and nose were looking for the wrong things?
No, of course not.
For exactly the same reasons one cannot say the dogs and the machines are not working correctly.
