Vac purge problems

I have my extract in a heated vac chamber and I usually keep the heat at 90-97f which keeps the bho at 80-88f. The first few hours it purged like usual, now it is not bubbling at all and hasn’t all day. I have 2 vacuum pumps, I tried both and got the same result. I’ve changed the oil and checked the fittings, I tested the pump by hooking up the vacuum gauge directly to the inlet and it is pulling vacuum, the chamber lid is suctioned on as tight as usual. I tried pushing the temp up to 110, which should have my concentrate around 105, thinking it would help the gas escape, but nothing still…this is one of my best runs yet! I don’t want to fuck it all up, please help.

What process used to extract?

Pressurized closed column soak, then open blast through the column. If that’s what you meant by process.

How much vacuum are you able to pull?

ended up being a small leak at the fitting on my chamber, getting a vac oven for following runs and that should take out some of the guesswork
