McDonald’s customers have one question in common: Why is the ice cream machine always broken? Theories abound about why the company’s soft serve machines seem to be nonfunctional so frequently. These theories range from conspiracy to simple laziness on the part of some McDonald’s employees, as employees report that the McDonald’s soft serve machines are rather difficult to clean.
… A former McDonald’s employee just shared why the ice cream machines are so often “broken” — and she tells us they aren’t. She shared: “If [the machine] is running out of mix for the ice cream … and no one fills it up, it goes into what’s called ‘heat treat mode,’ and it takes ages for it to come back down from that — so it’s easier just to say it’s broken.”
… Multiple sources say “heat treatment” is designed to clean the machine.
