Two-Cup Button is Making A Strange Noise

My Breville Barista Express is under 1 year old and I have been taking the recommended measures to take care of it. Yesterday I decalcified it, just like I have done in the past. However all of a sudden it just started making a high-pitched buzzing noise when I press the two-cup button? Should I panic? Does this need to be taken in for repairs or is there a simpler solution?

    Thanks for the suggestion to fix my problem, but I have no idea how to 'back flush' my machine or where to find 'back flushing powder'. Perhaps some more details about that process would help?
    As well, the machine's buzzing and crackling noise seems to get worse if I brew more than 1 shot at a time. Then again, the problem seems intermittent -any chance that there is a connection issue with the electrical panel and the button> would re-programming the automatic settings help?

    Any suggestions are greatly appreciated!

    Thanks for lengthy explanation Mark.
    I completely understand what you mean now in regards to the back flushing. In my Breville manual cleaning guide it references the same process you are describing, it's just a Breville brand cleaning tablet (not described as flushing powder) that gets placed into the rubber disc and then you carry out the cleaning. I think it's a good idea, so I will try it.
    I also understand what you mean about the back valve. (I am just apprehensive to start poking around too much with the components on my machine). It does seem to be struggling with bringing water through to the group head. The steaming process isn't affected. I have tried running water through with and without the portafilter in place and it always makes the buzzing noise.
    I will try cleaning the machine and hopefully that will help.

    Again, thanks for your tips. It's most appreciated.

    Hi There,

    back flushing - with your machine there should of been a rubber or plastic disc(sometimes they strap them to the machineor inside a pannel ) , you place the disc into the coffee handle with a product called coffee clear but I'm from New Zealand and maybe called something else where you are from. Press the espresso button let the machine run for about 15sec and stop repeat the process three to for times, once completed repeat the process again with no product to rinse group head and to remove any left over product.I suggest trying a department store for the product.

    I believe the buzzing noise is the valve that opens to allow water to flow through the group head this may not happen all the time. I dont think the buttons on the front would cause this as this would be low voltage.

    Re-programming would not fix this fault.

    Does the the noise appar when running hot water or steaming?.

    Kind regards

SOURCE: after using coffee that was too small, I can't make coffee with one of the filters

I'm not sure you can. I did exactly the same thing, the very first time I used it -- I phoned Breville support and they told me to try soaking the filter in 2 tsp of baking soda dissolved in a cup of warm water. Which kinda seemed to work, although it was bit occasionally reluctant to give me my damned coffee.

I struggled on with it for maybe a year, but then the rubber seal around the bit the filter connects to blew out (with rather dramatic results). I think the extra pressure of the blocked filter did more damage that I suspected.

I got it serviced and they replaced both the seal and the filter. Worked great after that...

...until last week, when water started pouring out where no water should pour. Turns out that the black lock block that the filter holder goes into has developed a crack.

Looks like another trip to the service agent for me.

In short, you could try cleaning the 1-cup filter, but I would reccommend giving it up as a bad job and just buying another.

Before It Is Too Late.

SOURCE: Breville Cafe Roma ESP8XL - cup is moving during the process

Once you've got the tamp right: no more rattles! The perfect tamp also makes a better cup of espresso.
The single hole is not a cheapo, lazy manufacturing defect.  The Cafe Roma has a "double walled" basket which is to produce a thicker crema.  The single hole is designed to allow pressure to build up behind it thus forcing a jet effect in the basket, giving the the coffee its crema.  This, by the way, is why it is also a sloppy/wet puck rather than a dry one.
The thump during steaming just gives me something to dance to in the morning.  "When the saints go marching in" always seems to come to mind;  perfect timing.
I am very happy with my Cafe Roma.  Just took some practice.
Happy espresso to you,

A dirty grinder or plunger will make your coffee dirty. Try mixing some vinagar and water (2 parts water and 1 part white vinegar) and then run it through your machine to clean out the inside.

Grinder jam on breville barista express

Only way to know for sure is by taking it completely apart and expose all the internal parts
Popping is not a good sign If it is electrical arcing you are playing with fire
or electrocution
If you are mechanically inclined they are not that hard to take apart as long as they have no security screws on it and you have to remember you might be voiding your warranty
But it is fun taking things apart No?

No steam or pump noise

get a used starbucks barista by saeco for a couple'll be pleased. (know i am-and i only paid $25 for my year old breville esp8xl POS). verify it works-it will probably last longer & perform better. if inclined/capable, maybe you can replace the pump yourself (a new one's prob in $35-$40 range; if more, scrap the machine or sell it "as is" for parts & put the money toward a better machine. good luck!
