My Minima is set to 9 bar and holds it constant with blind basket. Recently the pressure has dropped during the shot from 9 to 7-8 bar.
I thought it was old beans but even with fresh Red Brick it does same. I’ve backflushed with puly and same.
I wdt and now rdt as well (only change in last few days). Last shot was 20 in, 42 out in 32 seconds, my usual recipe, but after ramping to 9 bar it only held that for a few seconds before slowly falling to 7.5bar before I stopped the shot.
I’ve had gushers in 20 seconds still hold 9 bar. Could it be the lelit paddle causing problems or another blockage in the flow somewhere?
