I have been running my Elektra T1 using a static supply (from a bucket) for testing purposes, and I managed to let air into the system by letting the water level get too low. There was only a split second where the pump was trying to draw from the low water level until I noticed and stopped the cycle; however this was enough to get sufficient air in the system to affect water flow from the group during a brew cycle.

Just wondering if anyone knows the best / easiest way to bleed the air from the system?

Not sure about the T1 but with the A3 I run the machine through a brew cycle and open the steam as if relieving false pressure. I imagine it would be the same for T1.
