Earlier quoted context omitted.
Depends if it's luxury or commercial. Commercial products are generally able to be fixed, but there is a quite a price premium on them.
Commercial and consumer dishwashers are only the same in that they're both called "dishwashers" and use water. The former expect little to no food, have cycles measured in minutes, and run at temperatures that would eat more sensitive dishes alive.
A commercial dishwasher will cut right through amounts of food that a normal residential dishwasher wouldn't touch (pre-wash is more for efficiency and to keep crap from piling up in the bottom tray of the dishwasher) and it will actually be ever so slightly less harsh on whatever goes in it (plastics are the problem mostly) because while it washes and rinses way hotter it doesn't have a stupid heating element that runs to dry things.
It will also use fucktons more water and more power and make more noise.
