Depending on whick detection system you would be using. Every thing but the DD2 detects blocked nozzle by pump running. This type of detection is only on the 2d and 2s systems.
As for the air leak causing a bubble, the air leak is on the pull side of the pump. The inlet side of the pump creates a vacuum. A small leak and develop at the filter connection that is small enough to let air in but water will not flow out. The 5 bar in the line is being held but the pump output check valve. It is the air getting traped in the pump or pump feed line that causes the problems.

Gotcha.

Most of my plumbing is on the outlet side of the pump - so I was focused there as possible leak points.

The leaks were obvious when I connected another tank of water high up (instead of the pump) so water was leaking everywhere. In the normal setup everything was nice, tight and dry (that's why it could be sneaky)

The telltale is the pump being noisy and the bubbles on the high pressure line.

If you want to see my setup, do a search on my website for 'methanol'
