Unfortunate to see. I don't think that's going to buff out, so yeah, I think replacement is in order. Sorry, can't help with the timeline, never had to do that.

Bianca is fantastically well packed.
And the metal is very tough.
If both boxes are intact, this could not have happened during transportation.

Pump/group head pressure questions:

Just received a Bianca from Clive Coffee. So far it has been fantastic and I love it! The pump pressure from Clive was set at 11 bar. That makes group head pressure up around 11+. Seems too high to me and from what I have read Lelit recommends 10bar pump pressure? I chatted with Clive and they recommend 11 Bar on the pump.

Anyone have any advice/recommendation on "best" pump pressure? With the flow control I can obviously limit group head pressure but just want to make sure my pump is "set" correctly.

Thanks!

I have 11 bars on the pump.
And that is great. And then the flow regulator is in your hand.

I immediately dropped mine to 9 bar. Anything over that you're asking for channeling unless you are drinking some dark roasted stuff. I rarely ever pull a shot at 9 bar. I usually take it to 7-8 bar peak and then let the pressure naturally decay thanks to the perfection that is a needle valve.

FWIW a Londinium peaks around 7.5 bar. Lower peak promotes a more even pour especially with light roasts.

thanks for the info!

I think I'm going to drop my down, 9-10. seems like there are plenty of "how to" videos.

It is extremely easy. There is a little nut under the right side of the machine, that lets you adjust the OPV pressure without opening up the machine in any way. Will take a few seconds tops.

Don't forget that usually in a lot of e61 machines, when you adjust the opv for 9 bars, the pressure at the group head comes down to 8 ish bars, traditionally. Bianca (and perhaps other Lelit machines too) seems to have the same pressure throughout, as we can see the pressure at the head with the included manometer. Don't be afraid to get it slightly under 9, to match other e61 machines, to increase consistency.

And since it is SUPER easy to do, what you can also try is to pull the exact same shot, with 6 bars pressure (use the paddle for that and keep it at 6 bars manually), and see what that does to your shot. You might need to adjust the grind for it depending on the bean, but still give it a go. It's the beauty of having the valve, makes it sooo easy!
