I just got the Breville Barista Express 870xl last friday. I've been trying to pull a 2 shot single wall all weekend but can not get the pressure meter into the gray recommended area. Just wondering if anyone has had this issue and how to resolve it?

I must have wasted 2.5 bags of coffee beans testing this over the weekend. With a 1 shot single wall, I can pull shot with pressure gauge in the right area.

How many grams of coffee are you using. You may need to invest in a cheap scale. I recommend a 500g .01 resolution. Two things to do. Increase dose. try 17g. Grind finer. If you are at finest setting i think that unit has another setting for the top burr. Problem is that your coffee is not providing enough resistance for pump

That gauge isn't all that accurate. Like bluenoser suggests get a scale and go from there
