Fails at leak check. During steps 30, 35, 40, the load TC was at 100% (leak at front of tube?) Door interlock ok. Also, source TC has a small "b". This might explain why the tube had polypump loaded,, but in ready mode (vented) when I found it this morning. After first leak check failure, I visually inspected the gasket seal and didn't see any gross particles that might cause a leak. I tried running the program again, but same problem, gross failure at pump down and leak check. I will check the gasket more closely after this second leak check failure.
