Can I fix this myself?

No. This fault sits on the technician side of the line — do the user-serviceable checks on this page and no more. Anything involving the boiler, a pressure valve, the heating element or internal wiring needs a qualified technician.

Where do these steps come from?

They are transcribed from the Oracle Touch Instruction Book BES990, Troubleshooting p.25. We do not repair machines and we do not publish a fix we cannot cite to the manufacturer.

Will this code clear on its own?

Maintenance prompts clear when the cycle they are asking for is completed in full — stopping partway usually leaves the counter running. Fault codes clear when the underlying condition is corrected, not by power-cycling past them.

1. Contact the Breville Customer Service Centre. Breville publishes no user-serviceable remedy for this message.

When to stop and call a technician

This fault is on the technician side of that line. Do the user-serviceable checks above and no more.

The machine trips a breaker, smells of burning, or shows scorched wiring.
Water is leaking from inside the chassis rather than from the tank, tray or portafilter.
The fault involves the boiler, a pressure valve, the heating element or the pump itself.
The code returns immediately after a correctly completed reset or maintenance cycle.
The machine is under warranty — opening it yourself usually ends that cover.

Never bypass, disable or remove a safety device — a thermal fuse, pressure relief valve or lid interlock is the part standing between a fault and a fire. Do not open a pressurised boiler or work on mains wiring.
