Breville BES920 Steam Leak Fix (+ Triac Board Failure) 

Hi, in case anyone else is wondering. I just sorted mine. Replaced the 3 thyristors (2x Q6015L6 TO-220 and 1x BTA06-600CW TRIAC TO-220) but still didn't work, ended up replacing the octocouplers as well (3 black chips with 6 legs in the video EL3063 DIP6 MOC3063) and the machine is good to go again 👍

So, "debugging" didn't fix it. But pro-o-ringing did!

Hello. You think is possible that a kitchen bug to damage the electronic board on a Breville Barista Max espressor?

My machine also stopped working couple of days ago. There was also a leak, same as in your video. But after replacing the O-Ring the machine still overheats. The board itself looks fine, so no (external) signs of a water damage. But the board in this video also looked fine. Is there a way to test the board? Right now I don’t really know what to do, the pumps all seem to work , at least they are making lots of noises and the boilers also are filling up. Can’t see any other leaks. To bottom of the solenoid valve also looks like new.

Great video! Where can I find a replacement circuit board?

My machine just stopped responding to the power button. I suspect shorted triacs or controllers.

Who do you source the parts from? Also what is the part number for the O- Ring? Ps thanks for posting

i thought it was stainless steel and not rubber hose. Steam or hot water through plastic is bad, right?

Hey David, did you end up getting a replacement triac or replace the whole board?

Any good place to get replacement o rings and parts. USA southwest Arizona?

Same question as Dave K

Do you happen to have any idea why steam is coming out into my portafilter when I have the steam wand turned on? My Breville is a single boiler so steam is only suppose to come out of one place at a time. Thanks for any ideas.

Hi David, what is the O-ring size? I have same problem and like to buy O-Ring replacement.
