Investigating why McDonald's ice cream machines are often broken [video]
Tldw: the machine throws obscure error codes (too viscous, failure to heat to proper temps, etc) and can “lock out” the operator, who has to then call an authorized service technician that bills hundreds of dollars for repair. Any attempt to self repair or hire someone else will void the warranty and is disallowed by McDonald’s corporate. The ice cream maker company, Taylor, reports 25% of their revenue is service and maintenance.
