Hi Everyone,

Took delivery of my new Bianca yesterday and looking for advice on dialling it in. I'm using a niche grinder (which is also brand new) with fresh beans (two weeks old). The niche is set at on 23. and I'm putting 18g into the porta filter, aiming for 25-32 seconds to get 36g out. I've pulled a couple of shots and it's taking approx 10-12 seconds before any liquid appears and I reach 36g in 32 secs, which seemed about right. However I noticed the pressure was always around 4bar, despite the paddle being in the fully open position. To set a baseline (before playing with the paddle) I'd like to be getting at least 9bar and pulling the shots 25-32 secs for 36g out.

How do I get the pressure up? Is the grind too coarse or too fine? I've got the porta filter pretty tight in the head. Am applying reasonable pressure when tamping. Any help is much appreciated as I don't want to waste time and good coffee going down blind alleys.

Marcus

Hi Everyone,

schoolboy error; was using the larger basket (20g). Have changed the basket to 18g and will try again.

Also, might not have secured the porta filter enough at the start of each shot, as subsequent shots have been at 9bar since I've made a point of tightening a touch more.

Paddle is in the open position as I'm trying to establish a baseline.

Didn't notice the pump pressure, will look out for it now.
