Applies to: Dual Boiler.
How to fix 06
- Tank full and seated, then power cycle and let the machine attempt a fill.
- Descale as the manual describes, including the steam boiler cycle if your model has one. Technician sources say scale on a level probe can read as "no water".
- The Dual Boiler self-check menu shows boiler level status (such as LLL for low and HHH for high). A technician video links a probe stuck on HHH with a boiler that sounds empty to a scaled or shorted probe. Treat the menu readings as a guide, since Breville does not document them.
- Cleaning the probes, replacing their o-rings and checking the inlet hose means opening the machine and working near mains voltage, so it is technician work.
- If the fill pump buzzes and no water reaches the boiler, a technician would check the pump.
When to stop and call a repairer
Water and mains electricity share the top of the boiler. Do not open the machine or touch the probes.

How to check the error log
Switch the machine off at the wall. Hold EXIT and MANUAL while switching the power back on to enter the self-check menu. Technician videos say it shows boiler level status (such as LLL for low and HHH for high) and temperatures in the order coffee boiler, steam boiler, group head. The same videos say the stored error codes (00 to 12, with a count for each) sit in a separate engineer menu, opened by holding 1 CUP and 2 CUP and pressing the power button. Breville does not document either menu, so treat these steps as unconfirmed.
Clear the log after a repair so you can tell whether the fault has really gone.
Beyond the fix
Tips and tricks
- Self-check item 4 shows the three probe states as letters: L means no water detected, H means water detected. Compare with whether the boiler really sounds full or empty.technician video
- After a descale, try one run without the water filter. New filters can stay stiff and block flow, giving the same three-beep symptom.owner video
- If the pump stops after a few seconds, an air lock is likely. Some owners report relief by cooling the machine and following the drain-valve method in the video, but only for seconds at a time.owner video
- Priming a machine that sat dry for a long period sometimes needs water pushed in at the tank connection; use a clean squeeze bottle as shown.owner video
Common mistakes
- Descaling repeatedly to fix a steam problem that began after a descale; this can worsen probe and fuse trouble.
- Letting the pump run for long periods while trying to clear an air lock on an older machine.
Easily confused with
- Code 07 and the silent three-beep fault on the Dual Boiler look alike: the video describes three beeps with no error on the display, so check the self-check menu and error log.

Questions
What does 06 mean on the Breville / Sage Dual Boiler?
Steam boiler pump issue during startup. The steam boiler and its pump is not reporting what the controller expects: the boiler should be filling and the level probes should register water, and they do not. Scaled probes, a blocked inlet line, a fill pump that has stopped moving water, or a probe seal leak are the causes technician sources describe. Breville does not publish this code table, so the meaning comes from third-party service tables.
Can I fix 06 myself?
DIY difficulty: hard. Tank full and seated, then power cycle and let the machine attempt a fill. Descale as the manual describes, including the steam boiler cycle if your model has one. Technician sources say scale on a level probe can read as "no water".

Is it worth repairing?
Often yes, but Breville does not publish part or repair costs. Ask for a quote.
When does 06 typically show up?
Breville / Sage Dual Boilers report 06 during the power-on self-test. That timing is a useful clue when narrowing the cause.
Can I keep using the machine with 06 showing?
Usually you can finish the drink you are making, but do not ignore it — the underlying fault rarely heals itself. Work through the cheap checks first.
Will 06 clear on its own?
Rarely. A reset or power cycle is worth one try, but 06 with a "hard" difficulty rating almost always means a failed component that has to be replaced.
How long does the repair take?
This one is a bench repair for most owners — the teardown, test and reassembly are the bulk of the work, not the part itself.
