Sage coffee machines use a combination of error messages, flashing lights, warning indicators and system alerts to notify users of maintenance requirements, operating faults and safety shutdowns. Unlike many bean-to-cup coffee machines, most Sage espresso machines do not display traditional numbered fault codes. Instead, they communicate issues through illuminated buttons, flashing lights, display messages or warning symbols.

• Normal use over time.
• Hard water deposits inside the hydraulic system.
• Water filter overdue for replacement.
