Tried to run an O2 polymer cleanup, but plasma was bright pink/rose colored.  Tried to run a nitride etch to see if the O2 line or the chamber was the problem, and the system never reached a suitable base pressure (never started flowing gases or running RF).  Machine was unresponsive to "clear wafer" command during failed pumpdown.  Tried cleaning chamber seal with a dry cleanroom wipe effect.
