H62Water flow switch abnormality

Name in the manufacturer's documentation (service manual): Water flow switch abnormality[1]

In plain words (editorial)

The water flow switch does not detect enough water flow and the unit has stopped. The service manual lists the water pump, a water leak, a connector, the flow switch and the PCB as causes.

When to call a service technician: If the code returns after a restart, call the installer.
