Same code, same fix on the Oracle. Everything below applies to both.
Applies to: Oracle Touch.
How to fix ER06
- Switch the machine off at the wall, wait 60 seconds and switch it back on. A one-off reading glitch clears; a real open circuit comes straight back.
- Reaching the coffee boiler temperature sensor (NTC) plug means opening the machine, which is technician work. A technician would check that plug on the control board for corrosion or heat marks and test the sensor circuit. Tell them the code you see.
- Look under and around the machine, from the outside, for water trails. Moisture on a connector can read as an open or short circuit; a technician would find and fix the leak behind it, often a boiler o-ring or hose clip.
- If the code returns, the coffee boiler temperature sensor (NTC) or its wiring needs replacing by a technician.
- Afterwards, clear the stored error (see how to read the error log below) so you can tell whether it recurs.
When to stop and call a repairer
Stop and book service if you see water leaking, a burning smell or any scorch marks. Do not open the machine yourself.

How to check the error log
Switch the machine off at the wall. Hold the front Power button, switch the wall power back on and release when the logo appears. Enter the service password 00000, then open Error Counter (stored faults) or Live Debug (live temperatures and water levels). One technician video says the entry method differs between machines built before and after 2018, so if this does not work, do not keep trying.
Clear the log after a repair so you can tell whether the fault has really gone.
Beyond the fix
Tips and tricks
- Use cold, filtered water. The manual says distilled or demineralised water may affect the taste of the coffee, and links non-stop pumping and wet steam to such water.manufacturer manual
- Descale only through Settings and Descale Cycle, as the manual instructs. Breville's own descale solution is what a technician recommended on the touch models.technician video
- Limescale on boiler probes is a common cause of odd heating faults. Cleaning or replacing probes means opening the lid, so it is a job for a qualified technician.technician video
Common mistakes
- Descaling any other way than Settings and Descale Cycle. The manual warns that damage to the machine could occur.
- Opening the lid to poke at wiring or probes on a mains-powered machine. Technicians treat that as qualified work.
Easily confused with
- On the Barista Touch BES880, ER05 is reported as the milk jug sensor, not the coffee boiler. Check your model before following a Barista Touch guide.

Questions
What does ER06 mean on the Breville / Sage Oracle Touch?
Coffee boiler temperature sensor lost during operation. The control board cannot read the coffee boiler temperature sensor (NTC). On this code the sensor reads as an open circuit: the wire has come off, the plug is loose or corroded, or the sensor itself has failed. Because it dropped out mid-cycle, a loose or heat-damaged connection is the most likely cause. Breville does not publish this code table, so the meaning comes from third-party service tables.
Can I fix ER06 myself?
DIY difficulty: hard. Switch the machine off at the wall, wait 60 seconds and switch it back on. A one-off reading glitch clears; a real open circuit comes straight back. Reaching the coffee boiler temperature sensor (NTC) plug means opening the machine, which is technician work.

Is it worth repairing?
Often yes for a single sensor, but Breville does not publish repair costs. Get a quote first, especially on an older machine.
When does ER06 typically show up?
Breville / Sage Oracle Touchs report ER06 while brewing or steaming. That timing is a useful clue when narrowing the cause.
Can I keep using the machine with ER06 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 ER06 clear on its own?
Rarely. A reset or power cycle is worth one try, but ER06 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.
