Some newer bean-to-cup Cookworks machines use dedicated alarm indicators for water, coffee beans, the brew unit and descaling, while traditional espresso machines rely on power, coffee and steam indicator lights alongside operational faults. Understanding these indicators can help you quickly identify the cause of a problem and often restore normal operation without unnecessary repairs. The following guide covers the most common Cookworks warning lights and fault indicators found across the range.
