Update:

I am fairly there is something going on with software here.

I finally got around to setting up my second operating system: I use one for daily and normal games, and another purely for VR. I got the dual boot of the VR one set up today. I installed the drivers I needed to, and AquaSuite. I imported the Pump and LeakShield settings that I had exported from my main install.

The LeakShield now has a constant set point at a high level (over 400 millibar). I changed it to the "Use adaptive pressure preset" in the LeakShield set up, and it operates exactly the same way. Changing pump speed has no impact on the LeakShield's set point: It keeps going to max pressure in the new install.

The only thing I can think, is that I played around with "Virtual Flow Rate" on my main install. Even though I have attempted to disable it, perhaps there is some bug, or feature, where that existing virtual flow rate data is somehow impacting the adaptable set point on my main install, where the new install on the VR machine does not have any flow data, even incorrect data, and therefore runs max pressure all the time.

Update:

the machine was operating as expected, with release/shield cycles taking the pressure up to the set point and holding.

I powered off the machine for the first since my last cleaning update... It was off for approximately 4 hours.

On return I powered the machine on and it did cycle pressure up to maximum... I noticed this and once the software booted up (after a restart with admin and manual start of the service), it ran with lower than expected pressure (under the set point) and triggered an alarm after some minutes (frequent pressure loss). I recognised this behaviour, let the water temperature warm to operating (35 deg C, around 10 more than ambient), and redid numerous release/shield cycles. Every single time the patter is the same (see attached): it rises above set point, and falls some level below it. The calculated fill level, is again lower than expected (currently 74%).

My prediction is that if I power off the machine for some hours again, on boot, it will bring pressure up and it will fall even further below set point, closer to minimum, until eventually the original problem persists.

I am absolutely certain this has to do with condensation forming on the membrane, exacerbated by the cooling of the parts on the recent shutdown.

I really have no idea how to manage this, or if it is reflective of a faulty membrane, but it will be a difficult problem to accept, that I need to clean/dry the membrane each boot cycle.

I have emailed customer service before the weekend and am waiting on a response.

Will update when I know more

EDIT: note the change at 22:48:45 is my change of the pump from 40% to 50%, in an effort to drive up the set point and assess its impact on the behaviour of the pressure rise and fall on release/shield mode cycles.

Exactly.

To confirm, I have been running it since the last post... It holds pressure, but it certainly does not return the pressure back to the set point after release. Just did a release/shield mode and it's behaving exactly as I predicted: on re-pressurisation, it increases above set point and drops instantly to approx 50% between set point and minimum. It will get closer to minimum over time (release/shield cycles will drift further and further from set point).

I agree: I hope they can take a look as I am mostly sure this is software... perhaps it's membrane or solenoid but I can't speak to that... the reproducible nature of it makes me think it is software

I have tried to email twice this week and no response received The problem is now back again with the system pumping only enough pressure to take to minimum, which falls, then alarms go off. I hope I am not expected to clean and dry the leakshield membrane once every 5-6 days.

I had not seen that.

I'll wait for a reply. Thank you for the update.

Update: My opinion on my problem has changed... cleaning the membrane is giving diminishing results.... It is now not even letting me a Release/Shield cycle as it sometimes triggers an alarm during the test, as it just did.

I think a new membrane is required per one of the mods comments earlier in this post.

Have no idea. There's nothing I can see in the manual about it nor anywhere online, nor can I find the membrane itself. I'm just going by the earlier comment in here from Stephan on the 18th February, where he said it can be easily replaced without opening the LeakShield.

I'll update when I hear back from customer service, but right now It looks like I am going to have to switch my Leakshield to "release" and use it like a lid until the new membrane arrives.
