Schaerer Coffee Machine Message: Fill Powder Into 1st Container

What does Schaerer Fill choco or milk powder into 1st container mean?

This is a refill prompt on the Schaerer Coffee Soul for machines with powder containers. The table in chapter 14.4 states that the first powder container is empty, names that as the cause and gives one action: fill it. The container holds chocolate or milk powder, and the control cannot make a drink that needs it while it is empty, so the message asks for a refill. The manual does not say how the empty state is detected, what amount counts as low, or whether the other powder container can still be used, so we leave that out. The practical part is about the powder itself. Humid air makes powder lump, and lumps can block the dosing path even when the container is full. The table does not mention that, but if the message stays after filling, it is one of the first things a technician looks for. The message names the first container only; the second has its own message.
