The machine pasterizes the ice shake mix thru the night. Machines are cleaned weekly night nightly like some other places. It will automatically jump into heating mode by itself sometime around 11 and begin heating and pasturizing the mix. Sorry for the inconvenience. Hope this helps. I work there have for sometime and only outside maintenance clean the machines. I used to qork at Jack and what the other person commented was true but not at McDs.
Because the employees try to make it easier for them and clean the machine to early and then do t want to dirty it so they just lie and say it's broken... or they are just to lazy to make the Ice cream because it takes time... I know this because I worked there before ... keep calling and complaining about it so it does not keep on happening
Actually the machine was broken for several months. They have a new one now.
