So I can find almost no documentation about programming the pre-infusion aside from this video, it's not in the manual we got with the machine. We were able to get the pre-infusion running, but it seems like there must be more to programming it since in this video the rest period between the pump turning off and back on is about 4 seconds, but ours is less than 1 (which is obviously not very useful). Can you share any more details? Also it doesn't happen to support line-pressure pre-infusion does it?
Your pump pressure dial is reading 6 bar which is way to high for resting position. The manufacturers recommended max is 2-4 bar. The left group head constantly drips, so either your mains water in is very high or (which is more likely) the expansion valve on this machine is not functioning or has been over adjusted.
The left portafilter keeps leaking / dripping water , even though it is not in use

I'd also like to know about this
