System Leak Test Fail

After leak test is done it says : System leak test failed >350ml, and the other tests all pass.

same thing in an another machine, the machines seems to be working fine regardless!

I did the basic checks looking for the leak source, defective circuit, flow sensor, sodaLime canister, loose connectors and such but with no success I also replaced the ventilator with a one from an another machine, nothing changed.

Has anyone countered this issue?

Any lead would be appreciated

Hi AbSuf,

There are a few things to check. The leak is somewhere between the COZY and the high pressure side. Have you removed the vaporizer to run the check yet? Maybe the vaporizer is leaking. It's not usually a problem but it can happen. There is also a black pressure line that runs under the table top from the end of the vaporizer mounts over to the fresh air inlet of the COZY. I've had a leak there that took a week to figure out. 

Remove the back panel and check all the pressure sensing lines going to the main board. This machine is pretty old and these lines maybe be getting yellow and brittle. It's a good idea to change those out. Dreager sells the lines in lengths. 

Good Luck!
