Changing group head collar inserts on Breville Dual Boiler / Oracle / Oracle Touch (4 minutes) 2015+

In this video I show you how to change the group head collar inserts on your Breville Oracle or Dual Boiler series, versions 1522 and up (June 2015+) in case your group head is leaking despite changing the seal.
Time: 4 minutes
Tools: New collar inserts part number SP0009141 or SP0001815, Philips screw driver, Allen key hex tool, small prying scree driver or any thin tool really.
Do this if your collar (black flat plastic edge) is visibly damaged and your drop head is leaking water around it. Look and confirm with flash light. Sometimes a leaky group could mean a bad seal as well. This collar insert or the seal tend to fail around the 5 year mark on most Breville 900 series I've seen but can fail prematurely if using too much coffee or if using the wrong group head.
Previous to the June 2015 update, it was a longer job, more like 30 min involving opening the machine, removal of top lid and front panel, boiler, and group head screws.
Any questions please don't hesitate

Hi. Thanks for the video. Do you have one for the older version of the Dual Boiler, as I think that is the model I have?

[@PubRunner]

Thanks for the video. I have an Oracle that was given to us that has a bad brew boiler it’s popping the safety switch only when it’s hot. The resistance to earth on the left terminal on the brew boiler drops to about 90k ohms on the right terminal it’s about 9 meg ohms.
Do you have a video on how to replace it? I am a sparky and it doesn’t look hard.

@@PubRunner happy to help! sorry for the silly question but have you looked at the machine under full pressure and does it leak any steam? Steam leaks are the number one cause for popping safety switches and most overheating issues and anything showing funny behaviours. if you do have questions regarding electrical circuitry or motherboards and thermostats, join the Facebook dual boiler group and the Facebook breville owners group. A couple of the members there, namely Sean gambles and Luke Heunks, are very knowledgeable and sre breville techs familiar with this sort of thing

@@caffeinefix2751 yeah I have there is no condensation or signs of steam. I ran it with the lid off.
Btw I am an electrician by trade so I have half an idea what I am doing.
I disconnected the brew boiler by cutting the wire and measured the resistance to earth and when hot the resistance drops on the left hand terminal to about 90k when hot but about 7 Meg ohms when cold so I am as sure as I can be that the brew boiler is the issue. All the other elements meter fine to ground.
I can get the brew boiler, and two required hoses for $210. I would also do all the o rings and that’s another $19.
The other issue is the hot water dispenser doesn’t work but I did find the left hand hose was squashed this hose would be replaced with the new boulder as it is slightly different to what is in my machine
