Check that there is no blockage or leaks to the purge tubing. If a blockage has occurred, check the pedestal support plate purge inlet. In the event that there is a leak, check that the silicone tubing connecting the pedestal purge O2 to the stainless-steel tube on the loader assembly. The tubing may have become damaged as well during a broken pedestal event. Check the purge tubing in the oxygen/gases module towards the back as it may have a leak.
