Hey Sebastian!
The diagnostic suggested a clogged membrane. That's odd. Thanks for the tip! All it ever saw is just some DP Ultra. I was under the impression that the membrane is waterproof and it should be able to continue to operate even after coming into contact with the coolant. It was suggested on the forum that when the membrane gets wet, it stops working until it's dry again. I assumed it actually stops working, as in there would be some indication of this: perhaps an error message, it wouldn't turn on, etc.
The reservoir also have constant condensation on its wall and on the bottom of the Leakshield. It's a 100 tall Ultitube and it's about half full normally. I just leave this guy to air dry and I'll put it back tomorrow.
This didn't answer the original question though, that how do I make it to shut up about the frequent pumping? I had 0.1-0.5 mBar/min leakage from day 1 no matter what I did (and God knows I did try to troubleshoot it and I found that everything is as it should be). As I wrote the loop holds water just fine. It just doesn't hold the vacuum. So I'd still need a way to disable the triggering of the "too frequent pumping" alarm. I don't care how frequently it has to work. It either suck it up and keep pumping or I send it back for a refund, because how realistic is it to expect an air sealed water loop?
Make air tight water loops first, then we can come back to this expectation of 30 seconds a day and how frequently the pump should work. So ideally I don't want it to alarm at all, unless there's an actual sudden pressure drop, such as when I drill a hole into a tube or leave a fitting lose (like in the promo videos). That's the only alarm I would care about.
If it isn't pumping without stopping, then there's no leak to talk about.
