Not every Gaggia coffee machine uses the same software or display. Models such as the Brera, Anima, Magenta, Cadorna, Babila and Accademia may support different error codes depending on their generation, while some machines use warning lights instead of numeric codes. If your model displays an error not listed here, refer to your model-specific manual or troubleshooting guide.
