When the back pressure drops after it reaches 19 psi, this indicates there is a leak somewhere in the EV2. The easiest way to find a leak is to hook up to helium and use a leak detector. Then we can do a manual leak check to exacerbate the leak to make it easier to find with the leak detector.

To do a manual leak check go to Diagnostic tab. Energize the vent valve and dry purge valve. Next click on the sparge tube picture, this will bring up a pop window were we can enter a manual feed pressure. Click enter manual, then enter 20. Click out of the box to accept the change.

Using the leak detector find the leak and correct them. After correcting the leak, you can go to run status tab and step to standby, then go back to diagnostic to perform a leak check. Does your leak check pass?
