If the button is pressed in and lit, then the previous cycle is still running or it is finished but the user has not returned to turn the autoclave off and remove the load.
If the button is pressed in and unlit, then most likely the previous user did not un-press the button at the end of the run, and instead simply opened the door killing power by virtue of the door safety interlock switch.

This is true if the previous cycle was Fast or Dry, and possibly true if it was Liquid.

Most importantly, pressing this button is the last thing to do when initiating a run, and un-pressing this button is the first thing to do after the sterilization/exhaust cycles have ev
