Breville / Sage Barista Touch ER18: electrical safety protection triggered
ER18 means: E-fast protection triggered due to a detected electrical or safety fault.
How to fix ER18
- Unplug. Do not keep resetting the breaker; each trip is the machine telling you current is going where it should not.
- Let the machine dry for 24 hours somewhere warm. A machine that has been descaled or has a slow leak often has water around the element terminals.
- Check the mains cable and plug for damage and try a different socket on a different circuit.
- If it runs after drying, find and fix the leak (o-rings, hoses, boiler fittings) or it will return.
- If it trips again dry, the element insulation or the power board has failed. That is a technician job.
When to stop and call a repairer
This is a mains-electricity fault. Unless you are competent with live testing, hand it to a repairer.

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 to see stored faults or Live Debug for live temperatures.
Clear the log after a repair so you can tell whether the fault has really gone.

FAQ
What does ER18 mean on the Breville / Sage Barista Touch?
E-fast protection triggered due to a detected electrical or safety fault. The machine detected an electrical fault: leakage current to ground, an unexpected mains waveform, or a heater drawing power when it should not. Water on a heating element or the power board is the everyday cause. This is the code that also trips the GFCI / RCD in your kitchen.
Can I fix ER18 myself?
DIY difficulty: not recommended. Unplug. Do not keep resetting the breaker; each trip is the machine telling you current is going where it should not. Let the machine dry for 24 hours somewhere warm. A machine that has been descaled or has a slow leak often has water around the element terminals.
