Alright, so I set the preinfusion back to 2.5 bar (how it came from the factory) and pulled a shot using a 22g dose. It took almost 10 seconds of pulsing every second until the pressure needle moved. Then it continued to pulse until it hit 3.5 bar and held, I left it for about 10 seconds before releasing the lever. So it completely passed my preset.
When I watch the videos you all post, it pulses once or twice before reaching the pressure. I like how quick and quiet that is, and my pump pretty much runs until the lever is released. Is there any troubleshooting methods y’all recommend or do I need a new pump?
