As someone who came from a Barista Express machine to the BDB, I can't imagine how much more quiet it can get :lol:

Yes, that's the one. Guess I could try some heat to see if that works, but really don't want to strip the head out of those screws.

You are down to basic mechanic'ing skills now. I forget without looking into my machine, but are those screws threaded into metal or plastic. If plastic, don't use heat. The next step most would do would be to try an nice fresh sharp screwdriver tip.

And if it is corrosion that has frozen them, put it back with some lube so it doesn't happen again.

Do those screws look like phillips? If so try a JIS bit or driver. At least a couple screws in my machine were JIS. Picked up a JIS set on Amazon for approx 20cad.

It's metal to metal, so I may try the heat. Thanks for the info on the JIS screws, didn't know about this -will order the drivers since it seems they are safe to use on Phillps head screws, but you can't go the other way around.

I've had the BES920XL for about 4 years now. This morning I found what I believe to be the plastic grouphead collar insert broken, or at least I think it's broken. I did a normal short flush and water started coming out very oddly from the grouphead and kind of splashed out. I found an old thread with some folks talking about replacing the insert and I followed the link to here: https://www.ereplacementparts.com/colla ... 10640.html

I don't think this is the right part as some people also pointed out on that same thread. Any ideas on where to get the actual "whole" ring part?

The "whole ring" style is the old design that is now obsolete. You have two choices:

1) you can buy a new group for about $160 and replace it yourself. It's a fairly big though straightforward job (and it comes with a new portafilter too). It will be of the new design that uses the two piece insert scheme that is easy to do.

2) Send it in to Breville. For the fixed fee, which includes free shipping both ways AND they even pack it for you, they will either fix it or send you a brand new machine. My guess is it a bigger job than they want to pay for and they send you a new one.

What kind of portafilter? :shock:

Hey everyone, I'm curious about the pattern of water coming from the grouphead. I'm seeing water mostly coming from the edges only, donut style, but I'm not getting donut extractions. I'm wondering if this is common or something with the shower screen/dispersion disc? Ran clean cycle tonight and took everything apart to install the cafelat gasket when I noticed this happening. Thoughts?

The regular spouted one. Unfortunately. Though with a 58mm hole saw with carbide grit or carbide teeth, you can make it a bottomless. Use a good strong corded drill or one of the high voltage battery drills.

Mine came out like so:

You can also see where these portafilters are ^^^solid stainless steel^^^ and not plated brass
