Part of the issue as I understand it, is that the machine is fairly opaque as to why some failures occur can appear somewhat "flaky" as a result. When this occurs during a cleaning cycle, the whole cycle is void and a new 4 hour cycle must be run.
If the machine was clear about communicating the issue, it would be fine. It's not and can require a technician to come out with a tool to both read the machine status in detail and tweak the machine in the necessary ways to stop it being flaky.
This would all be fine except for the fact that
1. Only technicians from the manufacturer are allowed to be used.
2. Those technicians are unreasonable expensive.
3. The company could make the machines easier to diagnose and repair, but don't because repair calls are lucrative
4. Third parties can, and have, made tools that do make the machines easier to diagnose and repair without the need for a technician, but cant legally sell these solutions because it involves circumventing a digital lock (DMCA violation)
5. McD corporate has an agreement with the manufacturer to maintain this status quo in return for a kickback
