Twice I have had the screw that holds the shower screen to the group head shear off on its own. I have never adjusted it. Luckily, Williams-Sonoma has replaced it both times with out a fuss.

See photos click here

Has anyone else had this issue? What may be causing it? What can be done to prevent it?

Thanks in advance.

The link you provided brought me to a log-in screen so I didn't see your pix, BUT, to answer you question- NO. Holy crap NO! I take my group apart and soak it about once every two weeks and haven't had any issues. It doesn't have to go on super tight. Generally when I put it back together I tighten it after the machine has warmed up to temp but even there it's only hand tight. If you're having issues getting it loose maybe try it when it's hot? Be careful of course...

Click here for the pics

This sheering has occurred without my intervention.  I suspect that the screw may be self tightening to the point of sheering from the repeated friction of the grinds against the screw when the portafilter is attached. Does that make sense?

Is taking the group apart a recommended practice? I have never done that with this machine.

Make sure that you aren't using so much coffee that the grinds touch the screen.  As Illy says "around 5-6mm" of headspace.

That link worked trouble free!

The head space comment is a good one, with the Breville tamp you can see if you have the correct head space (and if you tamped level).

Wow, I can't imagine why that screw would be in that tight. That black ceramic part with the screw broken off is called the block (at least that's what I call it). The screw passes right threw it, so you most likely can still pull the block out after getting out the gasket.

The parts that I clean - basket, gasket, block, screw, screen, port-filter. While those are soaking in a cleaning solution I wipe down the group insides. Using a q-tip helps get in some of the more difficult areas.

So you're saying the screws came like that from Breville? That tight? Is it possible that you were driving it the wrong way since the screw is under the group? I'll be the first to admit that I've messed up the righty-righty/lefty-loosy thing on it because the screw is going up.

Hope you get that fixed soon...

Subject: Short shots all of a sudden
 

Hey everyone. I had a browse through a bunch of pages, and tried to search for this but couldn't find any info*

My 900XL suddenly began to deliver very short shots on the first button press, lasting 7 seconds or so, then subsequent presses (per coffee) it ran ~20 seconds. I thought maybe the pressure was too high and it cut out, but on the second coffee I checked and the level was 10bar give or take.

Has this happened to anyone else?

I reset the machine to no avail. I tested the water volume for both single and double shots (without coffee in the PF) and got~45ml for single, and ~60ml for double. I understand the 'correct' volumes should be 30ml and 60ml, but I assume this is espresso in the cup volumes, after a bunch of water has been left in the grinds?

I've now reset the shot timer to extract a right amount of espresso so things are ok**, but I was wondering why it suddenly stopped short.

Any thoughts would be appreciated. I've had my machine about 14 months now.

Cheers
Bart

  • Is there a way to search within a single thread?
    ** (didn't think to check the shot timer before I reset the machine or before I reset it myself, so I don't know whether it was just the shot timer which had reset itself.

There have been issues with the programmed button times. I'm not sure if there is a real fix for you but hopefully someone will chime in.

While some use the programmed buttons I think you will find that most on this thread use the manual button.

Espresso: BES900XL/B
Posted Mon Dec 2, 2013, 11:15am
Subject: Re: Breville Dual Boiler BES900XL Owners Thread
 

Very happy with the /B after 9 months.  Had the previous /A model for 6 months before a seal problem prompted Breville to replace it with the /B.

Questions for the experts:

- I flush the head for about 4 seconds after every pull and then wipe it clean.  I use a Q tip swab weekly to clean around the crevices of the group head.  I see that some of you are disassembling the group head and soaking it in cleanser fairly frequently.  Should I really be doing that?

- The pucks are still sticking much less on the /B and it seems that using the Breville tamper as a guide seems to help.  Instead of loading by weight, I have started loading by volume.  Just enough so that the shiny portion of the tamper almost goes flush with a very light tamp which I finish with my Zebra tamper.  This does not result in a double tamp.

- I've set it so that every double shot results in about two ounces and takes about 30 seconds @ 9 bar.  I use Lavazza Super Crema and these techniques are yielding the most consistently delicious pulls I've ever enjoyed on any machine.  Am I doing anything incorrectly?

In other words, what can I do better in terms of pulling great espresso and caring for the machine?

Thanks...

Thanks for the suggestions. I never touched the screw. I never took the group apart. One morning I took off the port-a-filter and everything just fell down.

I'll be extra careful about not overfilling the basket.

After pulling a shot is it typical to see an imprint of the shower screen on the puck? Or is this a sign of overfilling?

Okay, if you never touched the screw that's hardly your fault! There's no amount of espresso you can load into that basket to cause the screw to break.

Yes, AFTER you pull the shot you will see the imprint of the screen as the puck expands when it gets wet.

When you put in a dry puck, try taking it out and you should NOT see the screen imprint or and disruption of the puck. The Breville tamp already helps you there, but that's another way of checking. If your PF goes doesn't tighten until way past where it should (because of wear) then there may be less space for your puck.
