Harvest Right Vacuum Error #9 - Part 4 fixing sensor leak

We have started getting vacuum error #9 during the freeze and dry cycles.

In this series, we will be going over the steps we are taking to solve this problem.

I have seen lots of posts about this same error, and some still don't have any solution for the problem.
👉 The Freeze Dryer we have was manufactured in April 2022.
👉 We have only had it for a few months
👉 Currently we have completed 58 batches

We start out with the basic checklist and then work into the other possibilities.

Follow the series to see how it turns out.
