Assuming you replaced all check valves, including the 2 on the heat exchanger and the 1/4" NPT swing check coming from the exhaust manifold, rebuilt all the valves and checks in the 3 manifolds, replaced the ejector, and rebuilt both traps, (mainly the jacket trap, including the seat) and verified your transducer, calibration, and control, then my next check would be the door gasket leaking steam into the chamber during vac. Bad gasket, dirty channel, or both.
What are your vacuum levels and what is the temp reading when it bottoms out? Does a lot of steam come from the chamber after opening the door upon failure?
Oh, you did check the chamber drain strainer inside the chamber, right?

Sorry for not letting you guys know. This items is repaired. S1 was intermittantly sealing. Coil was good but the diaphragm assembly was bad.
