Some questions that I felt were not answered: 1. The video shows Taylor docs that have logo of Wendy's and other outlets that use their machines. So why those outlets are not facing the same issues? Do they use the same 602 model? Are the software versions same there i.e. same cryptic error codes? Any other differences compared to McDonalds? 2. One of Wendy's employees says that they wash the machine every night. Are…
In other words Wendy's and In-N-Out have more details procedures that the employees have to do (and "wash the machine" may include dumping all extra product, cleaning the insides and the dispensers) whereas the McDonald's "wash the machine" may be just clean the dispensers and load with product and let the machine do it's thing (and only every 14 days do a full clean).
But since the simpler machines trust the humans they can be made to run even if steps were missed.
