Same fermenter, same issue with cone heater, and same unhelpful response from Spike sadly (not sure what happened to them, their customer service used to have a fantastic reputation be very helpful). Unholy expensive to replace so frequently.
I ended up buying these hydroponic mats, which work...
This is a can of worms that just keeps popping open.
To my mind, the “correct” mash pH needs to be per some target for “best” ie best pH for fermentability, best pH for sugar extraction, best pH for flavor, etc.
I have always used 5.4 (measured at room temp) based on Palmer’s talks and books...
I’ve never seen bubbles come out the top
either…
Sure sounds like the spring got stuck, with a leak around it. It’s easy to disassemble and take a look, just make sure to remember the exact order and orientation of the different pieces around the plunger and spring.
If you mash for gravity 45 mins is often enough for hot/high-DP malts. But not the same as mashing for fermentability.
Long and low mashes yield more yeast-digestible short-chain sugars, which can really help to dry out certain beer styles. My own preference is for low RG in most beers...
I have the same Electric Brewery panel, which I mounted on a rolling TV stand. Very convenient. It's this one:

Cool stuff. Bobby I assume you move the QD from the HERMS input connection to the BK input when you run off the mash? How do you sparge?
EDIT -- Nvm !! Just watched the video you added. Love it.
