What does the Gevi Espresso Machine manual say about the indicator lights and what do they mean?

The Gevi espresso machine has three indicator lights that show different working conditions. The espresso function indicator uses low-speed (off) for preheating, medium-speed (flashing) when ready to brew, and high-speed (solid) when actively brewing. The steam function indicator uses the same pattern for milk steaming operations, and the hot water indicator shows when water is being discharged.
