IridiumBlackberry Furthermore, I’m also have the issue that when I’m pulling the shot, the pre infusion pressure is never met, it constantly tries to reach a pressure but never does. Is this normal behaviour too?
Pressurestat needs adjusting
Preinfusion pressure is controlled by the large centre screw, turn it towards + to get the pressure you want…probably 2bar
The dead band (point at which the pump turns on again when it senses a pressure drop), is too sensitive, smaller screw, offset from centre, turn it towards + until it stops pumping so often when idle and when pulling a shot. You might have to move it 1 full turn, try ½ a turn first.
