By the way, the reason the McDonald's ice cream machine is always down is because one company essentially provides all of the machines. As a result, they control the maintenance of it by having vague error codes and not providing a proper manual so that McDonald's employees wind up having to call their technicians to come and service it. Either that or the employees try running it through a clean cycle to try to fix the error which takes FOUR HOURS to complete and can't be interrupted.
That was a really good read, thanks for sharing it.
From the article…
The machine’s parts include no fewer than two dozen rubber and plastic O-rings of different sizes. Leave a single one out, and the pump can fail or liquid ingredients can leak out of the machine.
