The Breville / Sage Oracle shows this code with identical meaning and fix as the Oracle Touch. Full guide for ER26.
Applies to: Oracle.
How to fix Error 26
- Switch off at the wall immediately and let the machine cool for at least 60 minutes.
- Switch back on and watch the heat-up. If it reaches temperature normally and the code does not return, treat it as a one-off and descale as the manual describes.
- If it returns, technician sources point to a leaking steam probe seal, where steam heats the sensor cable and gives false overheat readings. Checking and replacing the probe o-rings means opening the machine, so it is a technician job.
- If the machine overheats again or steam pours from the group head at idle, a technician source says the triac board may be latched on. That is a board replacement, not a cleaning job.
- If the machine will not heat at all after an overheat, a technician source says a protective thermal fuse may have opened. Replacing it needs the machine opened up, so it is technician work.
When to stop and call a repairer
Do not keep running a machine that repeats an overheat code. Latched heaters can boil dry and damage the boiler and wiring.

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.
Beyond the fix
Tips and tricks
- If the machine feels warm long after switching off, unplug it and contact a technician.technician video
- Probe check: a repairer says probes can be twisted by hand in their insulators when the O-ring is failing; this needs the lid off, so it is for a technician.technician video
- Fixing the leak matters as much as replacing a damaged board.technician video
Common mistakes
- Running the machine with a visible steam leak at the top.
- Swapping the triac board alone when moisture caused the damage.
Easily confused with
- ER18 is the reverse: the steam boiler fails to warm.

Questions
What does Error 26 mean on the Breville / Sage Oracle?
Steam boiler overheated above target temperature. The steam boiler and its pump got hotter than the controller asked for. Technician sources describe two possible causes: the heater kept running when it was told to stop (a triac on the power board latched on), or the sensor under-reads because of a leak or steam at the probe seal. The machine cuts power to protect itself, and a technician source says repeated overheating can open a thermal fuse.
Can I fix Error 26 myself?
DIY difficulty: hard. Switch off at the wall immediately and let the machine cool for at least 60 minutes. Switch back on and watch the heat-up. If it reaches temperature normally and the code does not return, treat it as a one-off and descale as the manual describes.

Is it worth repairing?

When does Error 26 typically show up?
Breville / Sage Oracles report Error 26 any time. There is no reliable pattern to when it appears — treat any occurrence as real.
Can I keep using the machine with Error 26 showing?
Treat it as a stop-using signal: Error 26 marks a fault that can damage the machine (or worse) if you keep running it. Do the safe first steps below, then stop.
Will Error 26 clear on its own?
Rarely. A reset or power cycle is worth one try, but Error 26 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.
