Got Pressure tolerance problems in BT step at the 7 second mark. The P is oscillating wildly (up to 50mT sometimes!). Changed the BT time to 5 seconds to circumvent the problem temporarily. After a few wafers, got RF tolerance problem. Ran 2 chamber cleans. First one ran fine. Second one errored out with RF tolerance problem again. Maybe the machine needs a wet clean.
