Hello,
I've searched the forums here for years, but finally decided to join so I can post a question. I have a Breville Dual Boiler 920 that I've been working on for months now. I had a leaking steam wand ball valve, finally got a replacement part, and got that issue resolved. After replacing that part and replacing some o-rings in areas that were leaking, I got everything put back together, and ... steam boiler won't heat (dreaded 3 beeps when flipping the lever).
I've tried:
I know that the boiler is getting filled, and the espresso is still delightful. I just need this steam wand to work!
Thanks in advance for any help!

I've tried:
- Doing the hardness reset
- Descale
- Descale with a heated boiler
- Checking the probes for calcification
- Opening the drain valves and letting it sit overnight

Maybe a bad thermistor or thermocouple. Don't recall which the BDB uses. On other espresso machines.... that would be the first thing I would check.

I had the 3 beep issue after about 1.5 years with my 920 and after in the end I had to send the unit back to Breville for servicing :-/ I'm sure you are trying hard to avoid that so hopefully can find the fix yourself. Good luck!

Yes, I'm trying to avoid that! I will update if I fix it!
