Odds are the problem is the vacuum hose or its end connections, the drain valve, or the door gasket. Based upon my experience I'd double check the fittings while installed on the FDer.
Hopefully I said that in a way that makes sense! As well, does it matter which port is used as "in" and which as "out"?
Reattached hose and ran another full system test (results, 750 mTorr lowest steady reading - looking through the oil level window, some bubbling seen in oil even after an hour of pumpdown - some "air" noises from pump)

And therein lies the cons to buying a freeze dryer. It takes time to make them cost effective. Depending on humidity in your area, a single run can take up to two days to complete.
The current and emerging food crises in the United States have millions of Americans very concerned about the future. From supply chain shenanigans to food processing plants “inexplicably” being compromised to bird flu decimating the poultry industry, it’s no wonder there has been a sharp rise in the “prepper” food industry.
Investing in a freeze dryer is not just about saving money; it's about gaining the skills and resources to become more self-reliant and prepared for whatever life throws your way. So, invest in your self-reliance journey – your future self will thank you!
It appears that the ice build up inside the chamber sublimates as well as the ice in the food. Eliminate the ice and the process is faster, and less water ends up in your oil.
The two sub-processes, freezing and vacuum drying are done correctly: The freezing process must be quick and the vacuum process should leave only residual moisture.
Some essentials are needed to cook with the main food staples in long term food storage. These mostly are used to make breads from stored grains. The cooking essentials include salt, baking powder, baking soda, and yeast.
Removing water quickly is very important because the longer a harvested plant or compound retains water, the higher the chance it has of spoiling, losing nutrition, and losing potency.
But Electrolux provides a so-so website status for customer service. Electrolux aid is basically alright. If you live beyond An important metropolitan space, finding someone who can restore your device may be harder.
It would also be best to avoid pawn shops. Although they can be a goldmine for trinkets, they’re usually not a great place to shop for advanced machinery.
Without an pump isolation valve I would expect some air to flow back into the chamber through the pump resulting in the steady rise you witnessed. I saw the same phenomenon before I installed an isolation valve on my pump.
