Breville / Sage Oracle Error 16: temperature sensor short circuit
Error 16 means: Steam wand temperature sensor short circuit during operation.
How to fix Error 16
- Switch off at the wall and unplug. Leave the machine for an hour so any moisture in the connectors dries, then try again. A short that clears after drying tells you there is a leak to find.
- Inspect the steam wand where it enters the machine: scale or milk residue creeping into the wand can bridge the sensor. Deep-clean the wand and the tip; if it recurs, replace the wand assembly.
- Replace any leaking o-rings at the boiler fittings and NTC probes. Kits are cheap and the leak, not the sensor, is often the true fault.
- If the code persists after everything is dry, replace the steam wand temperature sensor (NTC).
- Clear the error log and run the machine through a full heat-up and a shot to confirm.
When to stop and call a repairer
If you see scorch marks on the triac board or the machine trips your GFCI / RCD, stop: that is an electrical fault, not just a sensor.
What it costs
Parts: Genuine NTC sensor assemblies run about $25 to $95 depending on which sensor it is (steam wand and milk-jug sensors are the dear ones). O-ring kits are $10 to $20.
Service: Out-of-warranty Breville service quotes for internal faults are commonly $300 to $500, sometimes more, plus shipping. Independent espresso repair shops are usually cheaper for a sensor swap.
Worth repairing? Yes in most cases. Sensor plus o-ring kit is well under $100. If a leak has soaked the control board, get a quote before spending anything.
How to check the error log
Leave the machine plugged in but switched off. Press and hold 1 CUP, 2 CUP and POWER together for at least one second. After the long beep the LCD shows the firmware version (starts with "Fr"). Press the SELECT dial once to open Error Storage, then rotate it to step through errors 1 to 32 and the stored count for each. Scroll past error 32 to "ErSt" and hold SELECT for 3 seconds to clear the log.
Clear the log after a repair so you can tell whether the fault has really gone.

FAQ
What does Error 16 mean on the Breville / Sage Oracle?
Steam wand temperature sensor short circuit during operation. The steam wand temperature sensor (NTC) is reading as a short circuit: the board sees near-zero resistance, which a healthy sensor never produces. The two real-world causes are water bridging the sensor contacts (a leak or steam at the probe seal) and a failed sensor. Because it happened during operation, heat or steam getting at the connector is the prime suspect.
Can I fix Error 16 myself?
DIY difficulty: moderate. Switch off at the wall and unplug. Leave the machine for an hour so any moisture in the connectors dries, then try again. A short that clears after drying tells you there is a leak to find. Inspect the steam wand where it enters the machine: scale or milk residue creeping into the wand can bridge the sensor. Deep-clean the wand and the tip; if it recurs, replace the wand assembly.
How much does it cost to fix Error 16?
Genuine NTC sensor assemblies run about $25 to $95 depending on which sensor it is (steam wand and milk-jug sensors are the dear ones). O-ring kits are $10 to $20. Out-of-warranty Breville service quotes for internal faults are commonly $300 to $500, sometimes more, plus shipping. Independent espresso repair shops are usually cheaper for a sensor swap.

When does Error 16 typically show up?
Breville / Sage Oracles report Error 16 while brewing or steaming. That timing is a useful clue when narrowing the cause.
Can I keep using the machine with Error 16 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 Error 16 clear on its own?
Sometimes. Try the reset and cleaning steps first — they cost nothing and clear the milder cases. A code that returns within a day or two needs the parts fix.
How long does the repair take?
Thirty minutes to an hour if you are comfortable opening the case; budget an afternoon the first time.
