Is this the end of the line for my Breville Dual Boiler 920xl?

Hi all!
I've had this machine for years and relied on this forum to help me troubleshoot and repair everything from O-rings to steam wand to pumps, OPV and solenoids. I'm grateful for all the help!

But it seems that I'm at a junction where I need to decide on feasibility of a repair on my own or send it back to Breville and await its fate based on the new non flat rate repair service.

The problem I'm dealing with is the following: no action from the steam boiler. Just three beeps when I attempt to activate the steam wand. Opening up the machine the steam boiler is cold, and obviously not coming up to temperature. From what I've surmised, it's probably the fuse associated with the boiler that lives on the right hand side halfway down the boiler. Also, looks like this repair may require soldering to replace. I'm not 100% sure though because I haven't found convincing repair roadmap to follow. Also I have zero soldering skills.

IF anyone can point me to a repair walk-through, I'd be grateful. If this sounds like a misdiagnosis, I'd also be open to some advice. breville troubleshooting had me run the descale - the boilers fill, it's just that the steam boiler water comes out cold.
Depending on the repair estimate from Breville, I'd be interested to also hear what machines people have moved onto after the BDB.
thanks in advance!

There's a very good chance that your problem is the thermal fuse on the side of the steam boiler, as you surmise. As to your soldering skills; For a few dollars and few hours of practice, you could remedy that lack. Or, there are several alternatives available these days that would require no soldering.

I would strongly advise against even "hardware store" crimp connectors and tooling. Professional grade connectors and a good quality crimper (typically compound action and sometimes ratcheting) are a good investment for working on espresso machines.

I typically buy my crimp connectors from an electronics supply house. T&B, AMP, FASTON are generally the brands I buy. They can also supply a bit higher-temperature covers for straight-in and flag-style connectors than what seem to be used by the original machine manufacturers.

The style of crimping tool that seems affordable yet secure would be one like the Klein https://www.kleintools.com/catalog/comb ... -terminals

I haven't used that specific tool. Others may have some specific recommendations.
