Help Leakshield not going over 79 mbar

Montag, 5. August 2024, 18:46

Hi,
I just replaced the membrane of my leakshield,
as my old coolant has touched it many times,
and the Leakshield was not passing any diagnostic even after cleaning.

It is now all green in dismounted conditions and passes the diagnostic,
but it fails diagnostics when mounted ?!

I refilled the loop with DP Ultra, and the loop is working great.
I tried the "DEAERATE" feature, but the negative pressure does not go over 76mbar.
I tried MONITOR mode, again it fails to go over 73mbar.
I have the ULTITUBE 100 and it is filled at 50%.
I don't see any leak. The coolant level is not going down.
I moved the case to remove bubbles, and the CPU does not heat much.

What should I do now to get the Leakshield to work ?
I'm out of ideas.

Use the test mode to ensure your system ist air tight.

Result below.
Does that look ok ?

It looks like your system is leaking completely.


You may only be able to test the Ultitube. So leakshield on the Ultitube and then seal the connections with a plug.
If this works, you need to find the leak in your system.
If this does not work, the leakshield may have a problem.

So if my system is leaking completely,
that diagnostic (in mounted conditions) does not reflect the reality ?








I also tested in dismounted conditions.
I now see "membrane test: failed".

The membrane is brand new ! I replaced it !
Ok I cleaned it with isopropanol and taping gently with a facial tissue.
Test failed again.

I have a brand new 2nd replacement membrane.
Could it be the 1st replacement membrane was bad ?

You have to narrow down the error. To do this, you first have to see what works and what doesn't.
If the Leakshield does not build up pressure:
1. leakshield defective
2. seal forgotten
3. a leak somewhere

What do the messages on the info (aquasuite) look like?
You must provide all available information. And preferably as precisely as possible.
Remote diagnosis is never easy without knowing the system.

I don't see any info tab in aquasuite.
I removed the seal of course (snap fit).

no, every membrane ist testet.
It is possible that residues from your old coolant have clogged the new membrane.


Replace the mebrane again or try clean your current membrane. Run the pressure test.

I came across the same thing.
Then device was produced in 2021, I unpacked and launched it today.

The loop was successfully pressure-tested to +0.75 bar (750 mbar) with no LeakShield installed yet. After installing the LeakShield, it can’t run either the “Test” or “Fill” routines. It gives maximum 92 mbar.

The sad story. Looks like the membrane is dead. I’m ordering now a new membrane to see if it works.

P..S.: the device was attached to the PC, firmware updated to the latest. I didnt touch the membrane and and didnt make regular pressure tests with Leakshield installed. So the device was properly handled but doesnt work out of the box.

I changed the membrane to a new one in accordance to the instruction with it.
No success.

Did anyone had same problem (doesn't create pressure)?
Is the device broken from the start?

Aquacomputer Leakshield weak sucking pressure

Freitag, 8. August 2025, 22:35

You are right.
After plenty of hours trying to figure out and solve the defect - I did it (but unfortunately destroyed the second membrane - which as appeared was not a cause of the problem too).

The problem was that the cap does not sit tight enough and only adding an extra ribber piece removed the leak from the Leakshield itself.

It looks like you want to fill your system. It is normal if no high pressure is built up. A correct assessment can only be made once the system is filled and sealed.

just updated the above message simultaneously with your reply.

So the problem found (see above), now I have to buy a third membrane.
