Breville Appliance Error Codes

Complete diagnostic guide for Breville coffee makers, espresso machines, toaster ovens, and smart ovens in the United States.

Important Note

Breville appliances use various error codes that vary by model and product line. Smart Oven models use E-codes (E01-E06), while espresso machines like Oracle Touch and Barista Touch use ER-codes (ER05, ER09, ER12, ER15, ER16, ER23, ER26).

Always refer to your specific model's user manual for model-specific error codes and troubleshooting procedures. Regular maintenance including cleaning and descaling can prevent many common errors.
