Do you have any insight into why the machines are broken so often then?
They aren't "broken". It's operations failures. The basic fact of 1. Keeping the machine full of the right amount of product to complete it's nightly heat cycle 2. Have someone trained to fully clean the machine every 14 days Is a burden too great for many franchisees to bear. The turnover is too high and investment in people too low to keep them operational. Nothing about them is "broken"
Why are they using such a complicated ice cream machine? I worked in food service in the 2010s and ours was pretty simple. One switch at the back for on and off and that was it. It took one person like 10 minutes to break it down and have it cleaned at the end of the night. The hardest part was wiping the exterior down. You basically just put a bucket underneath, ran the ice cream out, then ran hot water through it (forgot if we used some sort of sanitizer here), and hand washed a couple pieces. Other commercial icecream machines I've seen work like this. This mcdonalds machine is blowing my mind. I wonder why they opted not to use the bog standard ice cream machine every other fast food place uses.
