911Low flow rate error

Name in the manufacturer's documentation (service manual): Low flow rate error[1]

In plain words (editorial)

Low water flow error while the water pump should be running. The service manual lists a dirty strainer (water filter), air in the water system and heating loops closed without a bypass valve; it also asks to check that the water pressure is above 0.3 bar.

When to call a service technician: If the pressure is fine, call the installer to clean the strainer and vent the system.
