Umpires are subject to bias and grudges.
Machines are subject to interfearence. Since we don't know the exact system employed I can't say exactly ABC will happen, but trust me, all machines are subject to errors.
If it's based on light/laser beams they can be blocked, defective, inaccurate. The beams can be distorted by contaminates in the air.
If it's based on a HUD and sensors in the players uniform and balls the sensors can fail and the HUD can lose it's accurcy due to vibrations, shock from foul tips or dirt/dust. Sensors in uniforms will be subject to body heat, body sweat, dirt, dust, shock from sliding/foul tips/collisions. And those sensors have to be robust enough to survive washing after every game, but small enough to not inpede the player.
Again, since the system isn't defined I can't say what can go wrong. But if you know anything about machines/electronics/computers you know that they will go wrong and can be inaccurate if not maintained well.
