Can't really tell from your one pic. Bad deterioration after two years sounds a bit strange. You sure it isn't calcium scale that's falling off the insulator? My machine is seven years old and my probes are still fine, but I have 20-30 hardness water.

I initially thought it was calcium scale, but as I looked more closely I saw where the insulator and where the piece came from.

Hey, I had to put this project on the back burner for a minute, but wanted to revisit it as I am spending way too much money on cortados these days. I need to buy 3 new steam boiler probes - is there a good source for these? As I mentioned previously, the ceramic insulator is cracking and causing the steam to leak.

Thanks,
RR

Update: I ended up calling Breville and after viewing the issue on a video call, they agreed that the issue should not be occurring and agreed to repair it at no cost. My unit was close to two years old (I believe a bit older), so for others experiencing this issue, just give Breville a call and see what they'll do. Cheers

Thanks for this forum. How do I know if a probe is good or not? Mine is leaking from the probe itself, from the top. I do not see any o-rings in the probe. Do I have to dismantle the probe? I see it has a lock washer on the top. Thanks

The probe is held in the insulator by a small c-clip at the top. Pull that clip and the probe can be pushed down in the insulator, exposing a small o-ring at the bottom of the insulator.

I highly recommend replacing all the o-ring seals in the steam circuit at least semi annually. I do mine annually.
